PES Technical Council Activities
The JTCM meeting schedule for 2019 through January of 2020 will be as follows:
· Friday, April 12, 2019 - Webex Meeting · August 4 - 8, 2019 - 2019 GM in Atlanta, Georgia · January 12 – 13, 2020 - Hyatt Regency Hotel in Jacksonville, Florida.
PES will likely be implementing a yearly Technical Council retreat rather than every other year. This may also include a training session a day before the retreat for new Committee Chairs.
Farnoosh Rahmation will be working to develop an owner’s manual for Committee Chairs so that chairs are award of their responsibilities. This will include information such as start and end times, obligations, and links for additional information. Committees should also be looking for ways of transferring knowledge from past chairs to new chairs.
Susan McNelly and Joe Gravelle (Chair, Substation Committee) presented a webinar on February 5, 2019 on SC, WG, and TF activities in the 123Signup Association Management System (AMS). The webinar covered managing participants, recording attendance, creating meeting rosters and attendance reports, and using the AMS list server for sending emails to participants. The recorded webinar is available at: https://ieee.webex.com/mw3300/mywebex/nbrDownload.do?siteurl=ieee
4.2 TRANSFORMERS COMMITTEE ACTIVITIES
Page 21 of 43 Liaison Representatives - Appointed by Committee Chair. · ASTM D27 – Tom Prevost · CIGRE – Craig Swinderman · IEC TC-14 - Phil Hopkinson · Standards Coordinating Committee, SCC No. 18 (NFPA/NEC) – David Brender · Standards Coordinating Committee, SCC No. 4 (Electrical Insulation) - Evanne Wang
Committee Schedule There were again a number of last minute WG meeting cancelations. SC Chairs need to be pushing their associated WGs and TFs to make these decisions when the preliminary schedule is sent out for review. There should not be any big unknowns at that point in time that decisions on whether or not they need to meet can’t be made.
Meeting APP Dave Wallach has been researching alternatives to the Guidebook meeting APP that the Committee has been using for the past several years. Costs for this service have been rising and are presently on a per user basis. IEEE has indicated that they can provide a Word Press event site that would allow the meeting information, schedule, etc to be pushed to a mobile APP at a much lower cost than is presently being paid to Guidebook. Dave has proposed a trial of this system for the fall 2019 meeting in Columbus, Ohio.
Association Management System, 123 Signup All WG’s should be using AMS to track their membership and meeting attendance. If you are unable to so, please assign it to someone in your group. In addition to using the AMS, a list of names and affiliations must be included in the meeting minutes.
IEEE has transitioned to the use of the AMS, 123 Signup system as of the first of the year. The yearly cost to the Transformers Committee will be covered by IEEE. The Committee will still be responsible for any registration system and credit card fees.
Website Password Usage The website password is not for public dissemination. It is for use by our meeting attendees (CM, AP, II) and associated work of the Transformers Committee. Access to the protected information on the Committee website is a benefit of attendance and participation. It may be used by meeting attendees and within attendees’ immediate workplace, but not beyond that. A new password will be implemented immediately after the Jacksonville meeting.
Call for Patents (Essential Patent Claims) https://standards.ieee.org/about/sasb/patcom/patc.html A call for patents is required at every Working Group (WG) meeting. This is a reminder to all WG leaders to call for patents and record the results in the meeting minutes. Note it is not required to show the patent slides; it is only necessary to call for patents and record the response in the minutes. If there is a claim reported, the WG chair shall include in the minutes the name & affiliation of the individual asserting a patent claim. Here is what each WG Chair should ask at the beginning of each WG meeting. This applies only to WG’s after the PAR is approved by the IEEE-SA Standards Board. If anyone in this meeting is aware of any patent claims that are potentially essential to implementation of the document under consideration by this WG, that fact should be made known to the WG and recorded in the meeting minutes.
Page 22 of 43 There should be no discussion of any patent claim identified, only that it be identified and recorded. Even if no patent claims are identified, the minutes are to indicate that the call for patents was made.
If a patent holder or patent applicant is identified, then the WG Chair (or designee) should ask the patent holder or patent applicant of a patent claim that might be or become an Essential Patent Claim to complete and submit a Letter of Assurance in accordance with Clause 6 of the IEEE-SA Standards Board Bylaws.
A Letter of Assurance (LoA) is a document submitted to IEEE-SA by a patent holder which documents the submitter’s position with regards to ownership, enforcement, or licensing of an Essential Patent Claim that may be incorporated into a specific IEEE document. As of October 2018, the following six (6) existing Accepted Letters of Assurance pertain to our committee:

Patent Docket number 15/371,085.
Transformers Committee Policies and Procedures (P&P) Update A revised TC Sponsor P&P was voted on at the Jacksonville meeting and with some minor revisions by the Standards Board it has been approved. The Committee will be asked to reapprove the revised document as presently approved at the Anaheim meeting. The WG P&P has been revised and will be brought forward for the Adcom review and approval in Anaheim. If approved, an electronic vote of the committee members will be requested after the Anaheim meeting. An Entity WG P&P has also been created and will go through the same process for approval as the WG P&P.
Website Susan McNelly, the present Webmaster has started working on a transition from the present non web based web updating program to a web based platform. A base platform has been created and preparation for a transition to the new platform is nearly complete. Transition to the new platform will take place before the fall meeting in Columbus, Ohio.

Association Management System (AMS) Database
The Transformers Committee AMS database of people currently has three general categories of participation in our activities. These are: Interested Individual, Active Participant, and Committee Member. In addition, the Committee Secretary maintains a list of Past Committee Members. Anyone can join the AMS 123 system as the system is designed for self-registration. A new participant will automatically be assigned the role of Interested Individual when they first sign up. It is the responsibility of each individual to keep his/her profile updated (except for the participant status). Based on the level of participation, the committee administrative staff will upgrade the participation status to “Active Participant” when appropriate. The Committee Member status however, can only be attained through a formal application with the sponsorship of a minimum of three WG or SC chairmanships, at least one of which must be a SC Chair. Details of the application requirements and approval process by the Administrative Subcommittee are outlined in our O&P manual. The following table contains a count of the participants grouped by the four general categories (CM totals do not include those requesting membership at this meeting or Members to be moved to Past Member Status).

Interested Individual 72%
Active Participants 15%
6.2 COMMITTEE, SUBCOMMITTEES, AND WORKING GROUP ROSTERS
In order to provide indemnification to working group and subcommittee members it is crucial that membership lists be maintained. The AM system has these functions built-in to ease these administration tasks. It is important that each subcommittee and working group chair keep the rosters updated so that this information can be provided to the IEEE SA. Page 29 of 43 A similar main committee roster has also been developed to track attendance for the Main Committee General Session meeting on Monday & Thursday. The data will be used to update participant’s membership profile.
6.3 IEEE/PES AND IEEE/SA MEMBERSHIP REQUIREMENTS
As a reminder, all members of the Transformers Committee must also be members in good standing of the Power & Energy Society (IEEE/PES) and the Standards Association (IEEE/SA). WG Chairs must be members in good standing of the sponsoring subcommittee SC as well as the Power & Energy Society (IEEE/PES) and the Standards Association (IEEE/SA).
6.4 COMMITTEE MEMBERSHIP MAINTENANCE
An attendance audit was performed in March 2019 prior to the Spring Meeting. Because of the audit, the following 5 members who missed 4 or more Committee meetings in a row will be changed from Committee Member to Past Committee Member: 1. Adam Bromley 2. Fred Elliott 3. Paul Millward 4. Jane Ann Verner 5. Deanna Woods
Note that Past Committee Members can be reinstated to Committee Members if their status changes and they are able to regularly participate within two years of being changed to Past Committee Member.
6.5 ESSENTIAL PATENT CLAIMS
All registrants were asked to agree with the following statement: “I have read the Patent Claim notice on the following webpage, and I understand that if I am aware of any Essential Patent Claim related to issues being discussed or considered for inclusion in standards being developed by one or more Working Groups of the Transformers Committee, it is my responsibility to inform the Chair of the Working Group affected by such claim.” Working Group Chairs are asked to make a Call for Essential Patent at the beginning of each meeting and to record the results in the meeting minutes.
6.6 AFFILIATION
According to the IEEE Standards Board Bylaws, there is a requirement that participants of an IEEE meeting disclose their employer and affiliation. Consultants must state if they are sponsored or not. It is not sufficient to simply announce "My name is John Smith, and I'm a consultant." If a consultant is sponsored by a client, it must be disclosed. If the consultant does not have a sponsor, the proper introduction is something such as “My name is John Smith, I am a consultant, and I represent myself at this meeting.”
6.7 MEETING MINUTES
The minutes of the Fall 2018 meeting have been posted to the committee website. Thank you to everyone for submitting their minutes in a prompt fashion.
Page 30 of 43 Subcommittee Chairs are asked to submit their respective subcommittee meeting minutes for the Jacksonville meeting to the Committee Secretary no later May 9, 2019, which is 6 weeks after the completion of the meeting. It is strongly recommended that meeting minutes be prepared at or just after the meeting while the activities are still fresh in members’ minds. Doing so will help to ensure the activities and decisions made during the meeting are accurately reflected in the minutes. Subcommittee meeting minutes should be submitted via e-mail to the Committee Secretary, Ed teNyenhuis [[email protected]], who will forward them on to the webmaster for posting on the Committee website. The submittal file should be saved as a Word document formatted similar to this document. Attendance, indication of quorum, names of members making any motion, seconding any motion, and the result of any votes (affirmative and negative count) for each SC, WG, and TF meeting shall be included in all minutes. Respectfully submitted, Ed teNyenhuis Secretary IEEE/PES Transformers Committee March 25, 2019
7.0 TREASURER’S REPORT – PAUL BOMAN The Treasurer’s Report was presented at the Monday General Session. The Treasurer’s Report is included as Appendix 8.
8.0 RECOGNITION AND AWARDS REPORT – STEPHEN ANTOSZ
8.1 IN MEMORIAM
Dr. Robert Degeneff Robert (Bob) Degeneff passed away on March 16, 2019. Bob, who was 76, was a committee member for 26 years, and was known industry wide for his pioneering work in transient modeling of transformers. He was a leader and teacher for the committee, but most importantly, a friend to all of us and many colleagues around the world. Our thoughts and condolences go out to the Degeneff family. Bob was born in 1943, and started his professional journey in 1962 completing a BSME from General Motors Institute (Kettering University) and a Masters of Engineering in Electric Power at Rensselaer Polytechnic Institute (RPI). Bob served four years in the Air Force. After leaving the service, he joined General Electric Company’s Power Transformer Department and at the same time worked on achieving his Doctorate from RPI. He worked for GE for 16 years and next became a professor at RPI in the world wide recognized Electric Power Department. He also founded his own company for consulting and the production of power quality mitigation products that are in use around the world.
Page 31 of 43 In addition to his professional career, he was an active participant in the Electric Power community as an active participant in IEEE and CIGRE. Early in his career, he was Secretary, Treasurer, Vice-Chairman, and Chairman of the Berkshire Section of the IEEE and throughout his career; he participated in numerous working groups in both IEEE and CIGRE. A key contribution was his leadership of the working group that developed the guide for facilitating the understanding of switching transients induced by transformer, switching device and system interaction. Bob also served for many years as our Technical Editor. He was recognized as an IEEE Fellow, in 1993, for his contributions to the modeling and computation of transient voltages in transformer windings, was awarded the IEEE Herman Halperin award and the Transformers Committees’ 2015 Distinguished Service award. Bob held eight patents, published a book and numerous papers (two of which were IEEE prize papers) and technical articles, and was a professional Engineer in the State of New York Bob was also committed to his family and was an active participant in his church. In his free time, he enjoyed woodworking and associated antique tools, history, raising fruit trees, bee keeping, and collecting old technical books.
John Luksich John Luksich died unexpectedly at home on January 31, 2019 at age 64. He is survived by his wife Carol and two children Halle and Max. John actively served on several WGs in both the Insulating Fluids and Insulation Life subcommittees of the IEEE Transformer Committee. He was a Principal Engineer with Cargill Industrial Specialties, focused on natural and synthetic ester insulating liquids. Prior to Cargill, he spent 15 years as a Senior Engineer in the Dielectric Fluids group of Cooper Power Systems. Mr. Luksich received his B.Sc. in Chemistry and M.Sc. in Materials Engineering, both from the University of Wisconsin. He was also active in the ASTM D27 Committee. He has authored or co-authored more than two dozen technical papers on ester dielectric fluids, with special focus on quantifying improved cellulose life when impregnated with natural esters insulating liquids.
Tribute: Alan Sbravati - John was more than a colleague, a true professor. A tough one, with limited patience for lazy students. If you demonstrated real technical interest and asked the right questions, he would always be willing to share his extensive knowledge and go deep in a variety of topics. A great person who will be highly missed.”

Born Jan 1947, died March 2019 after a brief illness. Walter began his career at ELIN Transformers in Austria, and VA TECH Peebles Transformers Ltd located in Edinburgh, UK. As engineer and head of R&D, Walter served as CEO of VA TECH Peebles Transformers Ltd from 2002 till 2004 before he founded his own engineering company. Walter held several patents and his R&D work focused on development of models for mechanical winding oscillations and investigations on resonance behavior with special consideration of damping representation. He contributed to several international engineering committees like IEEE, CIGRE where he published several remarkable papers. One of his noteworthy achievements was his leading role in the development of the world’s first 525 kV phase shifting transformers for Salt River Project in 1996. He contributed to the first IEEE Guide for Application, Specification and Testing of Phase-Shifting Transformers C57.135, and at CIGRE with “Phase shifting transformers. Discussion of specific characteristics” in 1998. His work on phase shifting transformers was ground-breaking and is referenced by other authors in notable industry papers on phase shifting transformers. Walter received a prize paper award in IEEE-PES Transformers Committee coauthored together with H. Foschum, Loren B Wagenaar, and Jeff Fleemann for the Investigation of an EHV Autotransformer Tested with Open and Arrester Terminated Terminals in 1996.

11.3 STANDARDS COORDINATING COMMITTEE NO. 18 (NFPA/NEC) – DAVID BRENDER
To: Sue McNelly, Chair IEEE Transformers Committee March 7, 2019
Report on Panel Ballot on proposed revisions that will affect the 2020 National Electrical Code, and of interest to the IEEE Transformers Committee 1. The balloting of members of Panel 9, which, among other things, governs transformers was completed in January, 2019. 2. There was a total of 11 proposals that passed voting of the Panel. 10 proposals were editorial in nature and will have no substantive effect. 3. The only change of significance (albeit minor) was in NEC Section 450.9, where the following change was added to the language: “Transformer top surfaces that are horizontal and readily accessible shall be marked to prohibit storage.” 4. Final voting to approve the 2020 National Electrical Code will take place at the NFPA Annual Meeting, to be held in San Antonio, Texas, the week of June 17, 2019. At that time, any IEEE member who has registered in advance may make a motion and argue to change the Panel’s vote, seeking a positive affirmation of the motion by a majority vote of those present. Highly unlikely outcome, but it is possible.
Important note: IEEE representation on the NEC is through the IEEE SCC18. As of this writing, the IEEE Alternate seat on Panel 9 is vacant. Panel 9 has responsibility for articles covering, among other items, boxes, outlets, conduit bodies, fittings, switches, switchgear and panelboards, and equipment over 1000 V nominal, in addition to transformers. Please contact me regarding questions on joining SCC18.

Standards Report To: Members of Transformers Committee March 25, 2019 From: Jim Graham, Standards Coordinator
Executive Summary This report covers Transformers Committee Standards activity from September 28, 2018 through March 21, 2019. During this time one new standard and three revisions to standards were approved by the Standards Association Board. Approvals for three additional standards are pending. During this same period, the Standards Association Board approved one PAR for a new standard; six PARs for Revisions; five PARs for extension, two PARs for modification, and one PAR for corrigendum. Seven standards expired in 2018 before work was completed. One standard (C57.136) was intentionally allowed to expire. Three standards are on a RevCom agenda for approval. The remaining three are in the sponsor ballot process. Six standards are scheduled to expire in 2019. Two of these standards (C57.111 and C57.121) will be intentionally allowed to expire. Four (4) documents are in draft development. Seven PARs are scheduled to expire in 2019. Two of these activities are on a RevCom agenda, two are in the sponsor ballot process, and three are in draft development.

Introduction to ASTM D27
Current Hot Topics
Future Meetings
3 Committee D27 on Electrical Insulating Liquids and Gases
ASTM Committee D27 on Electrical Insulating Liquids and Gases was formed in 1959. D27 meets twice each year, in November and May, with about 30 members participating in 12 meetings over two days. The Committee, with a membership of approximately 90 members, currently has jurisdiction of over 60 approved standards that are published in the Annual Book of ASTM Standards, Volume 10.03 4 D27 Committee Scope
The promotion of knowledge pertaining to electrical insulating liquids and gases, whether of synthetic or natural origin, and the recommendation of standards pertinent to these materials. The principal materials included in this scope are oils of petroleum origin, synthetic liquids, halogenated and other gases, when used, singularly or as combinations, as electrical insulation or as an environment for electrical insulation.
Standards peculiar to solid insulating materials and varnishes and the development of standards pertaining to the nonelectrical uses of liquid and gaseous materials are excluded from the scope of Committee D27. Development in these fields incidental to the normal work of Committee D27 will be coordinated with the appropriate technical committees of the Society. 5 Committee Officers

Treasurer’s Report
MEMORANDUM
March 3, 2019
To: Susan McNelly, Chair IEEE PES Transformers Committee
RE: IEEE PES Transformers Committee Treasurer's Report Spring 2019 Meeting (for reporting period 09/11/2018 to 01/31/2019)
Dear Susan,
The finances of the Committee are in good condition. As of January 31st (end of this reporting period), the balance in our account was $89,480.39.
FYI: January 31st was essentially a "snap-shot in time" after all income & expenses were resolved from the previous Fall 2018 Meeting in Jacksonville, and before we started spending significant funds for the Spring 2019 Meeting in Anaheim.
-One (1) video meeting projectors was replaced by the Jacksonville host hotel. -Grant for $6,436 received from Visit Jacksonville Organization for Fall 2018 Meeting. -Changed to the IEEE payment gateway for registration fee collection -Outward facing system is still 123signup. -2017 internal IEEE audit was satisfactory and making preparations for the 2018 internal IEEE audit.
See attached summary of the balance of this reporting period, and the previous periods.
Let me know if you have any questions or concerns.
Sincerely,
Paul E. Boman, Treasurer IEEE PES Transformers Committee

4. Discussions The TF began reviewing the proposed revisions in Draft 0. In some cases, there are statements in this WG document that are similar to statements in the recently revised Policies and Procedures for Standards Development for the Transformers Committee. It was agreed by consensus that the statements in the WG document should match as closely as practically possible with statements in the Transformers Committee document. The TF covered clauses 1 to 1.6, then jumped to cover 4.0-4.5 because it was considered important to review membership issues (Clause 4) while reviewing the membership definitions (Clause 1.6). After completing these clauses, the TF reviewed Clauses 2.0 to 3.3. The proposed revisions were discussed and, some were accepted as is, some were accepted with modifications, and some were rejected.

Transformers Committee' Working Groups Policies and Procedures for Standards Development
1.0 Introduction
Clause 1.0 through 1.5 shall not be modified except as follows: Where appropriate, replace shaded italics with the name of the Working Group and the name of the Sponsor. If the name of the Working Group is inserted only in the title (above) and at Clause 1.3, the Working Group will add the additional sentence shown in brackets, and replace [Working Group Name] in the remainder of the document with "the Working Group" or appropriate related form.
1.1 Role of Standards Development and these Procedures
This clause shall not be modified.
In today’s technological environment, standards play a critical role in product development and market competitiveness. In the IEEE, the responsibility for how a standard originates and evolves is managed by a Sponsor. It is essential in the management of a standard’s development to avoid any actions by the Sponsor or the participants that result in a violation of procedures. These procedures establish the necessary framework for a sound standardization process.
1.2 Conduct
This clause shall not be modified.
Meeting attendees and participants in standards activities shall demonstrate respect and courtesy toward each other and shall allow each participant a fair and equal opportunity to contribute to the meeting discussion. While participating in IEEE standards development activities, all Formatted: Highlight participants, including but not limited to, individuals, entity representatives, entity members, entities participating directly in the entity process, and entities participating indirectly in the individual process shall act in accordance with all applicable laws (nation-based and international), the IEEE Code of Conduct, the IEEE Code of Ethics, and with IEEE-SA Formatted: Highlight Standards Board Bylaws (see IEEE-SA Standards Board Bylaws Clause 5.2.1 on “Participation Formatted: Highlight in IEEE standards development”) and IEEE-SA Standards Board Operations Manual. Formatted: Highlight
Membership privileges can be lost through persistent violation of the fundamental principles of Formatted: Highlight operation or disregard of standards of conduct. Formatted: Highlight Formatted: Highlight A Working Group Chair that suspects persistent violation of these principles or standards by an Formatted: Highlight individual shall refer the matter to the Sponsor. Formatted: Highlight 2
1.3 Modifications to These Procedures
This clause shall not be modified, except to identify Working Group.
These Policies and Procedures outline the orderly transaction of business by all Working Groups of the Transformers Committee, other than Entity Working groupsthe Working Group name Working Group, hereinafter referred to as “the Working Group”.
The Working Group may amend these procedures with the approval of its Sponsor. The Sponsor may modify these procedures. Modification in this context means that material in these procedures may be modified as long as that clause is not indicated as one that shall not be changed. The IEEE-SA Audit Committee (AudCom) strongly recommends that all subjects Formatted: Highlight included in these procedures are addressed by the Working Group or Sponsor.
None of the rules or requirements in these policies and procedures may be suspended. Formatted: Highlight
1.4 Hierarchy
This clause shall not be modified except to identify insert the name of the Sponsor.
Participants engaged in the development of standards shall comply with applicable federal, state, and international laws. In addition, for standards matters, the latest version of several documents takes precedence over these procedures in the following order:
New York State Not-for-Profit Corporation Law IEEE Certificate of Incorporation IEEE Constitution IEEE Bylaws IEEE Policies IEEE Board of Directors Resolutions IEEE Standards Association (IEEE-SA) Operations Manual IEEE-SA Board of Governors Resolutions IEEE-SA Standards Board Bylaws IEEE-SA Standards Board Operations Manual IEEE-SA Standards Board Resolutions
Policies and Procedures of the Transformers Committeeyour Sponsor
Robert's Rules of Order Newly Revised (RONR) is the recommended guide on questions of parliamentary procedure not addressed in these procedures.
1.5 Fundamental Principles of Operation 3
This clause shall not be modified.
For the development of standards, openness and due process are mandatory.
Openness requires that any person who has, or could be reasonably expected to have an interest, and who meets the requirements of these procedures, has a right to participate by:
a) Attending Working Group meetings (in person or electronically) b) Becoming a member of the Working Group c) Becoming an officer of the Working Group d) Expressing a position and its basis, e) Having that position considered, and f) Appealing if adversely affected.
IEEE due process requires a consensus of those parties interested in the project. Consensus is defined as at least a majority agreement, but not necessarily unanimity.
Due process is based upon equity and fair play. In addition, due process requires openness and balance (i.e., the standards development process shall strive to have a balance of interests and not to be dominated by any single interest category). However, for the IEEE-SA Sponsor ballot, there shall be a balance of interests without dominance by any single interest category.
1.6 Definitions
This clause shall not be modified except to include additional definitions.
Written communication includes but is not limited to meeting minutes, letter, email, and fax.
Sponsors of IEEE standards projects are committees that are responsible for the development and Formatted: Highlight coordination of the standards project and the maintenance of the standard after approval of the standard by the IEEE-SA Standards Board. (IEEE-SA Standards Board Bylaws 5.2.2).
Responsible Subcommittee is an optional subgroup of the Sponsor with delegated responsibility for approving PARs and Sponsor ballots. Responsible Subcommittees assist the Sponsor committee in the control and management of a large scope of work involving multiple working groups. A PAR study group or a working group (WG) is not a Responsible Subcommittee.
In this document, the term “Sponsor” means the sole Sponsor, the Responsible Subcommittee, or in the case of co-sponsored projects, the primary Sponsor.
4
A participant is an individual involved in the standards development process (see IEEE-SA Standards Board Bylaws Clause 5.2.1 on “Participation in IEEE standards development”). NOTE: Participants can be members or non-members of IEEE, IEEE-SA and/or of the working group.
A non-member is a participant who has not satisfied the criteria for membership defined in 4.1.
A member is a participant who has satisfied the criteria for membership defined in 4.1. A member is eligible to be listed on the WG roster.
A voting member is a member who has satisfied the criteria for voting membership defined in 4.1. A voting member can participate in working group motions and ballots.
A non-voting member is a member who has not satisfied the criteria for voting membership defined in 4.1.
[The relationship between the terms participant, non-member, member, voting member and non- voting member is illustrated in the following diagram:

Formatted: Highlight A voting member that fails to return 2 of the last 23 Working Group letter ballots in which they Formatted: Not Highlight are eligible to vote becomes a non-voting member. [Their existing attendances do not count towards regaining voting membership.] Formatted: Not Highlight Formatted: Highlight If a Working Group letter ballot closes within 14 days of a meeting, any changes to voting Formatted: Highlight membership resulting from the ballot shall be delayed until after the meeting.
[The chair may “specially maintain” a member’s voting status that would otherwise be lost by this WG letter ballot response rule. Reasons for such an action can include consideration of personal hardship, medical emergency, or outstanding contributions.] 13
4.4 Review of Membership
This clause shall not be modified, except to address the brackets.
The procedures for obtaining and retaining membership are specified in terms of meeting Formatted: Highlight attendances, [and Working Group letter ballots].
The Chair and Secretary should apply these procedures in a timely fashion, evaluating membership status in time for the next meeting [or Working Group letter ballot].
The Chair shall, at least annually, review the status of any members that are specially maintained to validate that the reasons are still applicable.
4.5 Working Group Membership Roster
This clause shall not be modified except to include or delete the optional bracketed text.
A Working Group roster is a vital aspect of standards development. It serves as a record of voting members and members in the Working Group and is an initial tool if an issue of indemnification arises during the process of standards development.
The Secretary shall make reasonable efforts to maintain a current Working Group roster. The roster shall include at least the following: a) Title of the Sponsor and its designation. b) Title of the Working Group and its designation. c) Officers: Chair, [Vice-Chair,] Secretary[, Treasurer]. d) Members: for each, include name, email address, affiliation, and status (e.g., voting member, non-member, etc.).
All Working Group members are required to review their information contained in the roster during or following each meeting they attend. If a Working Group meets only virtually, it shall determine a schedule to check the accuracy of the roster periodically.
A copy of the Working Group roster shall be supplied to the IEEE-SA at least annually by a Working Group officer or designee. Due to privacy concerns, the roster shall not be distributed, except to the IEEE-SA staff, IEEE-SA Board of Governors and IEEE-SA Standards Board, and the Standards Coordinator of the Transformers Committee, unless everybody on the roster has submitted their written approval for such distribution.
4.6 Working Group Membership Public List
This clause shall not be modified except for the distribution of the list. 14
A Working Group officer or designee shall maintain a current and accurate membership list. The membership list can be posted on the Working Group web site and can be publicly distributed. The membership list shall be limited to the following:

Such formation shall be explicitly noted in the meeting minutes. At the time of formation, the Working Group shall determine the scope and duties delegated to the subgroup, and may decide to allow participation of persons who are not Working Group members and specify the terms and conditions under which they participate in the subgroup. Any changes to its scope and duties will require the approval of the Working Group. Any resolution of a subgroup shall be subject to confirmation by the Working Group.
[The Chair of the Working Group shall appoint, and may dismiss, the Chair of the subgroup.] [The Working Group shall elect, and may remove, the Chair of the subgroup.]
6.0 Meetings
This clause shall not be modified except to modify shaded values.
Working Group meetings may be conducted either exclusively in-person or in-person with one or more participants contributing via electronic means, or exclusively via electronic means. Working Group meetings shall be held, as decided by the Working Group, the Chair, or by petition of 15 % or more of the voting members, to conduct business, such as making Formatted: Font: Not Italic assignments, receiving reports of work, progressing draft standards, resolving differences between subgroups, and considering views and objections from any source. A meeting notice shall be distributed to all members at least 30 days in advance of a face-to-face meeting and at Formatted: Font: Not Italic least 15 days notice in advance for an electronic (including teleconference) meeting. A meeting agenda (including participation information) shall be distributed to all members at least 10 days Formatted: Font: Not Italic in advance of a face-to-face meeting, and at least 5 days in advance for an electronic meeting. Formatted: Font: Not Italic (Meetings of subgroups may be held as decided upon by the members or Chair of the subgroup.) Notification of the potential for action shall be included on any distributed agendas for meetings.
15 While having a balance of all interested parties is not an official requirement for a Working Group, it is a desirable goal. As such, the officers of the Working Group should consider issues of balance and dominance that may arise and discuss them with the Sponsor.
Participants shall be asked to state their employer and affiliation at each Working Group meeting as required by the IEEE-SA SA Standards Board Operations Manual clause 5.1.2.3 on “Disclosure of affiliation”.
All IEEE standards development meetings are open to anyone who has a material interest and wishes to attend. However, some meetings may occur in Executive Session (see Clause 6.2).
6.1 Quorum
This clause shall not be modified except to increase the shaded values or to state quorum definitions otherwise approved by the Sponsor.
A quorum shall be identified before the initiation of Working Group business at a meeting, but if a quorum is not present, actions may be taken subject to confirmation by letter or electronic ballot, as detailed in Clause 7.2, or at the next Working Group meeting. When the voting Formatted: Highlight membership is less than 50 voting members, a quorum shall be defined as a majority of the current total voting membership. When the voting membership is 50 or more voting members, a quorum shall be defined as 10% of the current total voting membership or 26, whichever is greater. Voting members who recuse themselves shall not be counted in the equation to determine whether a quorum exists.

An individual may be invited to join for a portion of the discussion and then excused at the appropriate time. In each case, except as authorized by the Working Group, participants in an Executive Session are prohibited from discussing or disclosing any information presented and discussed during such Executive Session to a third party or other person not present during the Executive Session, and shall not continue to discuss such matters after the Executive Session has adjourned.
16
Executive Sessions should be conducted face-to-face (in person) to provide the greatest assurance that the content of such Executive Sessions will be kept confidential. However, when necessary, Executive Sessions may include participants who participate by teleconference provided such persons agree not to disclose any information so discussed, and agree that they will participate in such conference in a manner that does not result in third parties gaining access to such discussions or information.
6.3 Meeting Fees
This clause may be modified, or replaced by "Not Applicable.”

Transformers Committee Working Groups Policies and Procedures for Standards Development
1.0 Introduction
Clause 1.0 through 1.5 shall not be modified except as follows: Where appropriate, replace shaded italics with the name of the Working Group and the name of the Sponsor. If the name of the Working Group is inserted only in the title (above) and at Clause 1.3, the Working Group will add the additional sentence shown in brackets, and replace [Working Group Name] in the remainder of the document with "the Working Group" or appropriate related form.
1.1 Role of Standards Development and these Procedures
This clause shall not be modified.
In today’s technological environment, standards play a critical role in product development and market competitiveness. In the IEEE, the responsibility for how a standard originates and evolves is managed by a Sponsor. It is essential in the management of a standard’s development to avoid any actions by the Sponsor or the participants that result in a violation of procedures. These procedures establish the necessary framework for a sound standardization process.
1.2 Conduct
This clause shall not be modified.
Meeting attendees and participants in standards activities shall demonstrate respect and courtesy toward each other and shall allow each participant a fair and equal opportunity to contribute to the meeting discussion. While participating in IEEE standards development activities, all participants, including but not limited to, individuals, entity representatives, entity members, entities participating directly in the entity process, and entities participating indirectly in the individual process shall act in accordance with all applicable laws (nation-based and international), the IEEE Code of Conduct, the IEEE Code of Ethics, and with IEEE-SA Standards Board Bylaws (see IEEE-SA Standards Board Bylaws Clause 5.2.1 on “Participation in IEEE standards development”) and IEEE-SA Standards Board Operations Manual.
Membership privileges can be lost through persistent violation of the fundamental principles of operation or disregard of standards of conduct.
A Working Group Chair that suspects persistent violation of these principles or standards by an individual shall refer the matter to the Sponsor.

1.3 Modifications to These Procedures
This clause shall not be modified, except to identify Working Group.
These Policies and Procedures outline the orderly transaction of business by all Working Groups of the Transformers Committee, other than Entity Working groups, hereinafter referred to as “the Working Group”.
The Working Group may amend these procedures with the approval of its Sponsor. The Sponsor may modify these procedures. Modification in this context means that material in these procedures may be modified as long as that clause is not indicated as one that shall not be changed. The IEEE-SA Audit Committee (AudCom) strongly recommends that all subjects included in these procedures are addressed by the Working Group or Sponsor.
None of the rules or requirements in these policies and procedures may be suspended.
1.4 Hierarchy
This clause shall not be modified except to identify insert the name of the Sponsor.
Participants engaged in the development of standards shall comply with applicable federal, state, and international laws. In addition, for standards matters, the latest version of several documents takes precedence over these procedures in the following order:
New York State Not-for-Profit Corporation Law IEEE Certificate of Incorporation IEEE Constitution IEEE Bylaws IEEE Policies IEEE Board of Directors Resolutions IEEE Standards Association (IEEE-SA) Operations Manual IEEE-SA Board of Governors Resolutions IEEE-SA Standards Board Bylaws IEEE-SA Standards Board Operations Manual IEEE-SA Standards Board Resolutions
Policies and Procedures of the Transformers Committee
Robert's Rules of Order Newly Revised (RONR) is the recommended guide on questions of parliamentary procedure not addressed in these procedures.
1.5 Fundamental Principles of Operation
3
DRAFT 1
This clause shall not be modified.
For the development of standards, openness and due process are mandatory.
Openness requires that any person who has, or could be reasonably expected to have an interest, and who meets the requirements of these procedures, has a right to participate by:
a) Attending Working Group meetings (in person or electronically) b) Becoming a member of the Working Group c) Becoming an officer of the Working Group d) Expressing a position and its basis, e) Having that position considered, and f) Appealing if adversely affected.
IEEE due process requires a consensus of those parties interested in the project. Consensus is defined as at least a majority agreement, but not necessarily unanimity.
Due process is based upon equity and fair play. In addition, due process requires openness and balance (i.e., the standards development process shall strive to have a balance of interests and not to be dominated by any single interest category). However, for the IEEE-SA Sponsor ballot, there shall be a balance of interests without dominance by any single interest category.
1.6 Definitions
This clause shall not be modified except to include additional definitions.
Written communication includes but is not limited to meeting minutes, letter, email, and fax.
Sponsors of IEEE standards projects are committees that are responsible for the development and coordination of the standards project and the maintenance of the standard after approval of the standard by the IEEE-SA Standards Board. (IEEE-SA Standards Board Bylaws 5.2.2).
Responsible Subcommittee is an optional subgroup of the Sponsor with delegated responsibility for approving PARs and Sponsor ballots. Responsible Subcommittees assist the Sponsor committee in the control and management of a large scope of work involving multiple working groups. A PAR study group or a working group (WG) is not a Responsible Subcommittee.
In this document, the term “Sponsor” means the sole Sponsor, the Responsible Subcommittee, or in the case of co-sponsored projects, the primary Sponsor.
A participant is an individual involved in the standards development process (see IEEE-SA Standards Board Bylaws Clause 5.2.1 on “Participation in IEEE standards development”).

DRAFT 1
NOTE: Participants can be members or non-members of IEEE, IEEE-SA and/or of the working group.
A non-member is a participant who has not satisfied the criteria for membership defined in 4.1.
A member is a participant who has satisfied the criteria for membership defined in 4.1. A member is eligible to be listed on the WG roster.
A voting member is a member who has satisfied the criteria for voting membership defined in 4.1. A voting member can participate in working group motions and ballots.
A non-voting member is a member who has not satisfied the criteria for voting membership defined in 4.1.
The relationship between the terms participant, non-member, member, voting member and non- voting member is illustrated in the following diagram:
A letter ballot is a ballot conducted either electronically or by paper.
2.0 Working Group Responsibilities
This clause shall not be modified except to include additional responsibilities.
The Working Group shall:
a) Complete the project from Project Authorization Request (PAR) approval to IEEE-SA Standards Board approval as specified by the PAR, and in compliance with IEEE-SA policies and procedures. b) Use the IEEE-SA document template format [or the applicable template for standards jointly developed with, or adopted from, another international standards organization].
5
DRAFT 1
c) Submit to the Sponsor any documentation required by the Sponsor; e.g., a project schedule or a monthly status report. d) Notify the Sponsor of the draft development milestones. e) Notify the Sponsor when the draft is ready to begin IEEE-SA Sponsor ballot. f) Only those authorized to access and use IEEE’s data, including personal data, from IEEE systems are permitted to do so, for the purposes intended, including to support the technical development work on the standard, and only in compliance with IEEE or IEEE- SA Privacy and data privacy policies.
3.0 Officers
This clause shall not be modified except to include additional officers.
There shall be a Chair and a Secretary, and there should be a Vice-Chair. The office of Treasurer is suggested if significant funds are involved in the operation of the Working Group and/or its subgroups or if the group has multiple financial reports to supply to the IEEE-SA. A person may simultaneously hold the positions of Treasurer and another office, other than Chair.
The officers (and any person designated to manage the Sponsor ballot) shall each be IEEE members of any grade, or IEEE Society affiliates, and also be members of IEEE-SA.
3.1 Election or Appointment of Officers
This clause may be modified. (Three cases are provided; either choose one of these cases – Case 1, Case 2, or Case 3 – or create a similar process for this clause and delete the other options.) If Case 1 is selected, change title to “Appointment of Officers”. If case 2 is selected, use title without change. If case 3 is selected, change title to “Election of Officers”.
Case 1 – Chair appointed and Chair appoints other officers:
The Working Group Chair shall be appointed in accordance with the Sponsor’s procedures. After appointment of the Working Group Chair by the entity that established this Working Group, the Working Group Chair shall appoint a Vice-Chair, and Secretary.
The appointment of officers shall be for the duration of the PAR.
3.2 Temporary Appointments to Vacancies
This clause may be modified.
If an office other than the Chair is vacant for any reason (such as resignation, removal, lack of nomination at an election), a temporary appointment shall be made by the Chair for a period of up to 12 months. In the case of Chair, the Sponsor shall make the temporary appointment, with
6
DRAFT 1 input from the Working Group. An appointment or election for the vacated office shall be made in accordance with the requirements in Clauses 3.0 and 3.1 at the earliest practical time.
3.3 Removal of Officers
This clause may be modified. Two cases are provided; either choose one of these cases – Case 1 or Case 2 – or create a similar process for this clause and delete the other options.
A working group officer may be removed by approval of two-thirds of the members of the Working Group in Executive Session, or by the Responsible Subcommittee Chair. Removal of an officer by a Responsible Subcommittee Chair requires a two-thirds approval vote by the Administrative Subcommittee in Executive Session. In both cases, grounds for removal shall be included in any motion to remove an officer of the Working Group. The officer suggested for removal shall be given an opportunity to make a rebuttal prior to the vote on the motion for removal.
3.4 Responsibilities of Working Group Officers
This paragraph shall not be modified.
When carrying out the duties of an officer described in IEEE’s policies and procedures, officers of the Working Group:
a) shall not act: 1) in bad faith; 2) to the detriment of IEEE-SA; 3) to further the interest of any party outside IEEE over the interest of IEEE; or 4) in a manner that is inconsistent with the purposes or objectives of IEEE; and b) shall use reasonable efforts to ensure that participants of the Working Group conduct themselves in accordance with applicable policies and procedures including, but not limited to, the IEEE-SA Standards Board Bylaws clause on “Participation in IEEE standards development.” (See Clause 1.2.)
The officers of the Working Group shall manage the day-to-day operations of the Working Group. The officers are responsible for implementing the decisions of the Working Group and managing the activities that result from those decisions.

The Chair shall, at least annually, review the status of any members that are specially maintained to validate that the reasons are still applicable.
4.5 Working Group Membership Roster
This clause shall not be modified except to include or delete the optional bracketed text.
A Working Group roster is a vital aspect of standards development. It serves as a record of voting members and members in the Working Group and is an initial tool if an issue of indemnification arises during the process of standards development.
The Secretary shall make reasonable efforts to maintain a current Working Group roster. The roster shall include at least the following: a) Title of the Sponsor and its designation. b) Title of the Working Group and its designation. c) Officers: Chair, [Vice-Chair,] Secretary[, Treasurer]. d) Members: for each, include name, email address, affiliation, and status (e.g., voting member, non-member, etc.).

DRAFT 1
While having a balance of all interested parties is not an official requirement for a Working Group, it is a desirable goal. As such, the officers of the Working Group should consider issues of balance and dominance that may arise and discuss them with the Sponsor.
Participants shall be asked to state their employer and affiliation at each Working Group meeting as required by the IEEE-SA SA Standards Board Operations Manual clause 5.1.2.3 on “Disclosure of affiliation”.
All IEEE standards development meetings are open to anyone who has a material interest and wishes to attend. However, some meetings may occur in Executive Session (see Clause 6.2).
6.1 Quorum
This clause shall not be modified except to increase the shaded values or to state quorum definitions otherwise approved by the Sponsor.
A quorum shall be identified before the initiation of Working Group business at a meeting, but if a quorum is not present, actions may be taken subject to confirmation by letter or electronic ballot, as detailed in Clause 7.2, or at the next Working Group meeting. When the voting Formatted: Highlight membership is less than 50 voting members, a quorum shall be defined as a majority of the current total voting membership. When the voting membership is 50 or more voting members, a quorum shall be defined as 10% of the current total voting membership or 26, whichever is greater. Voting members who recuse themselves shall not be counted in the equation to determine whether a quorum exists.
6.2 Executive Session
This clause shall not be modified.
Meetings to discuss personnel or sensitive business matters (e.g., the negotiation of contracts), or for other appropriate non-public matters (e.g., the receipt of legal advice), may be conducted in Executive Session.
The matters discussed in executive session are confidential, and therefore, attendance at the Executive Session shall be limited to those with governance authority, outside advisors (e.g., lawyers or consultants) where necessary to provide professional guidance, and select IEEE-SA staff who may have information or a perspective relevant to the subject matter discussed in Executive Session. An individual may be invited to join for a portion of the discussion and then excused at the appropriate time. In each case, except as authorized by the Working Group, participants in an Executive Session are prohibited from discussing or disclosing any information presented and discussed during such Executive Session to a third party or other person not present during the Executive Session, and shall not continue to discuss such matters after the Executive Session has adjourned.

Transformers Committee Working Groups Policies and Procedures for Standards Development
1.0 Introduction
Clause 1.0 through 1.5 shall not be modified except as follows: Where appropriate, replace shaded italics with the name of the Working Group and the name of the Sponsor. If the name of the Working Group is inserted only in the title (above) and at Clause 1.3, the Working Group will add the additional sentence shown in brackets, and replace [Working Group Name] in the remainder of the document with "the Working Group" or appropriate related form.
1.1 Role of Standards Development and these Procedures
This clause shall not be modified.
In today’s technological environment, standards play a critical role in product development and market competitiveness. In the IEEE, the responsibility for how a standard originates and evolves is managed by a Sponsor. It is essential in the management of a standard’s development to avoid any actions by the Sponsor or the participants that result in a violation of procedures. These procedures establish the necessary framework for a sound standardization process.
1.2 Conduct
This clause shall not be modified.
Meeting attendees and participants in standards activities shall demonstrate respect and courtesy toward each other and shall allow each participant a fair and equal opportunity to contribute to the meeting discussion. While participating in IEEE standards development activities, all participants, including but not limited to, individuals, entity representatives, entity members, entities participating directly in the entity process, and entities participating indirectly in the individual process shall act in accordance with all applicable laws (nation-based and international), the IEEE Code of Conduct, the IEEE Code of Ethics, and with IEEE-SA Standards Board Bylaws (see IEEE-SA Standards Board Bylaws Clause 5.2.1 on “Participation in IEEE standards development”) and IEEE-SA Standards Board Operations Manual.
Membership privileges can be lost through persistent violation of the fundamental principles of operation or disregard of standards of conduct.
A Working Group Chair that suspects persistent violation of these principles or standards by an individual shall refer the matter to the Sponsor.
1.3 Modifications to These Procedures 2
DRAFT 2 (Final)
This clause shall not be modified, except to identify Working Group.
These Policies and Procedures outline the orderly transaction of business by all Working Groups of the Transformers Committee, other than Entity Working groups, hereinafter referred to as “the Working Group”.
The Working Group may amend these procedures with the approval of its Sponsor. The Sponsor may modify these procedures. Modification in this context means that material in these procedures may be modified as long as that clause is not indicated as one that shall not be changed. The IEEE-SA Audit Committee (AudCom) strongly recommends that all subjects included in these procedures are addressed by the Working Group or Sponsor.
None of the rules or requirements in these policies and procedures may be suspended.
1.4 Hierarchy
This clause shall not be modified except to identify insert the name of the Sponsor.
Participants engaged in the development of standards shall comply with applicable federal, state, and international laws. In addition, for standards matters, the latest version of several documents takes precedence over these procedures in the following order:
New York State Not-for-Profit Corporation Law IEEE Certificate of Incorporation IEEE Constitution IEEE Bylaws IEEE Policies IEEE Board of Directors Resolutions IEEE Standards Association (IEEE-SA) Operations Manual IEEE-SA Board of Governors Resolutions IEEE-SA Standards Board Bylaws IEEE-SA Standards Board Operations Manual IEEE-SA Standards Board Resolutions
Policies and Procedures of the Transformers Committee
Robert's Rules of Order Newly Revised (RONR) is the recommended guide on questions of parliamentary procedure not addressed in these procedures.
1.5 Fundamental Principles of Operation
This clause shall not be modified. 3
DRAFT 2 (Final)
For the development of standards, openness and due process are mandatory.
Openness requires that any person who has, or could be reasonably expected to have an interest, and who meets the requirements of these procedures, has a right to participate by:
a) Attending Working Group meetings (in person or electronically) b) Becoming a member of the Working Group c) Becoming an officer of the Working Group d) Expressing a position and its basis, e) Having that position considered, and f) Appealing if adversely affected.
IEEE due process requires a consensus of those parties interested in the project. Consensus is defined as at least a majority agreement, but not necessarily unanimity.
Due process is based upon equity and fair play. In addition, due process requires openness and balance (i.e., the standards development process shall strive to have a balance of interests and not to be dominated by any single interest category). However, for the IEEE-SA Sponsor ballot, there shall be a balance of interests without dominance by any single interest category.
1.6 Definitions
This clause shall not be modified except to include additional definitions.
Written communication includes but is not limited to meeting minutes, letter, email, and fax.
Sponsors of IEEE standards projects are committees that are responsible for the development and coordination of the standards project and the maintenance of the standard after approval of the standard by the IEEE-SA Standards Board. (IEEE-SA Standards Board Bylaws 5.2.2).
Responsible Subcommittee is an optional subgroup of the Sponsor with delegated responsibility for approving PARs and Sponsor ballots. Responsible Subcommittees assist the Sponsor committee in the control and management of a large scope of work involving multiple working groups. A PAR study group or a working group (WG) is not a Responsible Subcommittee.
In this document, the term “Sponsor” means the sole Sponsor, the Responsible Subcommittee, or in the case of co-sponsored projects, the primary Sponsor.
A participant is an individual involved in the standards development process (see IEEE-SA Standards Board Bylaws Clause 5.2.1 on “Participation in IEEE standards development”).

DRAFT 2 (Final)
NOTE: Participants can be members or non-members of IEEE, IEEE-SA and/or of the working group.
A non-member is a participant who has not satisfied the criteria for membership defined in 4.1.
A member is a participant who has satisfied the criteria for membership defined in 4.1. A member is eligible to be listed on the WG roster.
A voting member is a member who has satisfied the criteria for voting membership defined in 4.1. A voting member can participate in working group motions and ballots.
A non-voting member is a member who has not satisfied the criteria for voting membership defined in 4.1.
The relationship between the terms participant, non-member, member, voting member and non- voting member is illustrated in the following diagram:
A letter ballot is a ballot conducted either electronically or by paper.
2.0 Working Group Responsibilities
This clause shall not be modified except to include additional responsibilities.
The Working Group shall:
a) Complete the project from Project Authorization Request (PAR) approval to IEEE-SA Standards Board approval as specified by the PAR, and in compliance with IEEE-SA policies and procedures. b) Use the IEEE-SA document template format [or the applicable template for standards jointly developed with, or adopted from, another international standards organization].
5
DRAFT 2 (Final)
c) Submit to the Sponsor any documentation required by the Sponsor; e.g., a project schedule or a monthly status report. d) Notify the Sponsor of the draft development milestones. e) Notify the Sponsor when the draft is ready to begin IEEE-SA Sponsor ballot. f) Only those authorized to access and use IEEE’s data, including personal data, from IEEE systems are permitted to do so, for the purposes intended, including to support the technical development work on the standard, and only in compliance with IEEE or IEEE- SA Privacy and data privacy policies.
3.0 Officers
This clause shall not be modified except to include additional officers.
There shall be a Chair and a Secretary, and there should be a Vice-Chair. The office of Treasurer is suggested if significant funds are involved in the operation of the Working Group and/or its subgroups or if the group has multiple financial reports to supply to the IEEE-SA. A person may simultaneously hold the positions of Treasurer or Secretary and another office, other than Chair.
The officers (and any person designated to manage the Sponsor ballot) shall each be IEEE members of any grade, or IEEE Society affiliates, and also be members of IEEE-SA.
3.1 Election or Appointment of Officers
This clause may be modified. (Three cases are provided; either choose one of these cases – Case 1, Case 2, or Case 3 – or create a similar process for this clause and delete the other options.) If Case 1 is selected, change title to “Appointment of Officers”. If case 2 is selected, use title without change. If case 3 is selected, change title to “Election of Officers”.
Case 1 – Chair appointed and Chair appoints other officers:
The Working Group Chair shall be appointed in accordance with the Sponsor’s procedures. After appointment of the Working Group Chair by the entity that established this Working Group, the Working Group Chair shall appoint a Vice-Chair, and Secretary.
The appointment of officers shall be for the duration of the PAR.
3.2 Temporary Appointments to Vacancies
This clause may be modified.
If an office other than the Chair is vacant for any reason (such as resignation, removal, lack of nomination at an election), a temporary appointment shall be made by the Chair for a period of up to 12 months. In the case of Chair, the Sponsor shall make the temporary appointment, with
6
DRAFT 2 (Final) input from the Working Group. An appointment or election for the vacated office shall be made in accordance with the requirements in Clauses 3.0 and 3.1 at the earliest practical time.
3.3 Removal of Officers
This clause may be modified. Two cases are provided; either choose one of these cases – Case 1 or Case 2 – or create a similar process for this clause and delete the other options.
A working group officer may be removed by approval of two-thirds of the members of the Working Group in Executive Session, or by the Responsible Subcommittee Chair. Removal of an officer by a Responsible Subcommittee Chair requires a two-thirds approval vote by the Administrative Subcommittee in Executive Session. In both cases, grounds for removal shall be included in any motion to remove an officer of the Working Group. The officer suggested for removal shall be given an opportunity to make a rebuttal prior to the vote on the motion for removal.
3.4 Responsibilities of Working Group Officers
This paragraph shall not be modified.
When carrying out the duties of an officer described in IEEE’s policies and procedures, officers of the Working Group:
a) shall not act: 1) in bad faith; 2) to the detriment of IEEE-SA; 3) to further the interest of any party outside IEEE over the interest of IEEE; or 4) in a manner that is inconsistent with the purposes or objectives of IEEE; and b) shall use reasonable efforts to ensure that participants of the Working Group conduct themselves in accordance with applicable policies and procedures including, but not limited to, the IEEE-SA Standards Board Bylaws clause on “Participation in IEEE standards development.” (See Clause 1.2.)
The officers of the Working Group shall manage the day-to-day operations of the Working Group. The officers are responsible for implementing the decisions of the Working Group and managing the activities that result from those decisions.
The remainder of this clause may be modified to include additional officers and their responsibilities.

The Chair and Secretary should apply these procedures in a timely fashion, evaluating membership status in time for the next meeting or Working Group letter ballot.
The Chair shall, at least annually, review the status of any members that are specially maintained to validate that the reasons are still applicable. 11
DRAFT 2 (Final)
4.5 Working Group Membership Roster
This clause shall not be modified except to include or delete the optional bracketed text.
A Working Group roster is a vital aspect of standards development. It serves as a record of voting members and members in the Working Group and is an initial tool if an issue of indemnification arises during the process of standards development.
The Secretary shall make reasonable efforts to maintain a current Working Group roster. The roster shall include at least the following: a) Title of the Sponsor and its designation. b) Title of the Working Group and its designation. c) Officers: Chair, Vice-Chair, Secretary. d) Members: for each, include name, email address, affiliation, and status (e.g., voting member, non-member, etc.).

A meeting notice shall be distributed to all members at least 30 days in advance of a face-to-face meeting and at least 15 days notice in advance for an electronic (including teleconference) meeting. A meeting agenda (including participation information) shall be distributed to all members at least 10 days in advance of a face-to-face meeting, and at least 5 days in advance for an electronic meeting. (Meetings of subgroups may be held as decided upon by the members or Chair of the subgroup.) Notification of the potential for action shall be included on any distributed agendas for meetings.
While having a balance of all interested parties is not an official requirement for a Working Group, it is a desirable goal. As such, the officers of the Working Group should consider issues of balance and dominance that may arise and discuss them with the Sponsor.
Participants shall be asked to state their employer and affiliation at each Working Group meeting as required by the IEEE-SA SA Standards Board Operations Manual clause 5.1.2.3 on “Disclosure of affiliation”.
All IEEE standards development meetings are open to anyone who has a material interest and wishes to attend. However, some meetings may occur in Executive Session (see Clause 6.2).
6.1 Quorum
13
DRAFT 2 (Final)
This clause shall not be modified except to increase the shaded values or to state quorum definitions otherwise approved by the Sponsor.
A quorum shall be identified before the initiation of Working Group business at a meeting, but if a quorum is not present, actions may be taken subject to confirmation by letter or electronic ballot, as detailed in Clause 7.2, or at the next Working Group meeting. When the voting membership is less than 50 voting members, a quorum shall be defined as a majority of the current total voting membership. When the voting membership is 50 or more voting members, a quorum shall be defined as 50% of the current total voting membership or 26, whichever is greater. Voting members who recuse themselves shall not be counted in the equation to determine whether a quorum exists.
6.2 Executive Session
This clause shall not be modified.
Meetings to discuss personnel or sensitive business matters (e.g., the negotiation of contracts), or for other appropriate non-public matters (e.g., the receipt of legal advice), may be conducted in Executive Session.
The matters discussed in executive session are confidential, and therefore, attendance at the Executive Session shall be limited to those with governance authority, outside advisors (e.g., lawyers or consultants) where necessary to provide professional guidance, and select IEEE-SA staff who may have information or a perspective relevant to the subject matter discussed in Executive Session. An individual may be invited to join for a portion of the discussion and then excused at the appropriate time. In each case, except as authorized by the Working Group, participants in an Executive Session are prohibited from discussing or disclosing any information presented and discussed during such Executive Session to a third party or other person not present during the Executive Session, and shall not continue to discuss such matters after the Executive Session has adjourned.
Executive Sessions should be conducted face-to-face (in person) to provide the greatest assurance that the content of such Executive Sessions will be kept confidential. However, when necessary, Executive Sessions may include participants who participate by teleconference provided such persons agree not to disclose any information so discussed, and agree that they will participate in such conference in a manner that does not result in third parties gaining access to such discussions or information.
6.3 Meeting Fees
This clause may be modified, or replaced by "Not Applicable.”
The Working Group, or meeting host, may charge a meeting fee to cover services needed for the conduct of the meeting. The fee shall not be used to restrict participation by any interested parties.

Minutes of the Meeting of the IEEE PES Transformers Committee Task Force on Revision of the Working Group Policies and Procedures
Meeting Date: February 7, 2019 Meeting Time: 1:30 PM – 2:45 PM EST Meeting Location: GoToMeeting Conference Call Members Present: Bruce Forsyth (Chair), Jim Graham, Peter Balma, Chuck Johnson, Steve Shull, Sue McNelly (ex-officio), David Wallach Members Absent: Kris Zibert
1. Welcome and Attendance The Chair opened the web meeting by welcoming the Task Force members and taking attendance. The Chair announced that Stephen Antosz asked to be removed from the TF due to scheduling conflicts, reducing the membership to 8 people. There were 7 of the 8 members on the call so a quorum was present.
2. Review and Approval of the Agenda The Chair presented the following agenda shown in Figure 1 for consideration. There were no changes requested.

Approval of the Minutes for the Previous Meeting The minutes of the previous meeting on January 16, 2019 were sent to the TF members via email prior to this meeting. There were no changes requested. A motion was made by Peter Balma (seconded by Steve Shull) to approve the minutes. There were no objections to unanimous approval of the minutes.
4. Discussions
4.1. This was the third meeting of the TF. The first two meetings focused on revising the existing WG P&P for the Individual Method and this meeting focused on creating the new WG P&P for the Entity Method. Prior to the meeting Jim Graham prepared a starting draft using the entity baseline document and the Individual WG P&P developed in the previous two TF meetings.
Before beginning discussions on the Entity WG P&P a discussion took place regarding Clause 3.1 of the Individual WG P&P. Specifically, it was proposed that the wording be revised to require a Secretary and a Vice Chair, but that the Vice Chair can fulfill the role of the Secretary. After some discussion the following language was accepted:
“After appointment of the Working Group Chair by the entity that established this Working Group, the Working Group Chair shall appoint a Vice-Chair and a Secretary. The Vice-Chair may fulfill the roles of both Vice-Chair and Secretary.”
4.2. A review of Draft 1 of the Entity WG P&P prepared by Jim Graham was reviewed. A few changes were made to make the Entity version match the Individual version. There were a few sections that were questioned, but since this is a new document and process for the Transformers Committee it was generally agreed to leave the wording as in the baseline document until such time as there is an issue that requires a review and possible revision.
One change that was made was to define a Sponsor Liaison as follows:
“A Sponsor Liaison is an individual appointed by the Sponsor to monitor the WG activities and report back to the Sponsor.”
4.3. After all sections were reviewed and any changes discussed and generally accepted, the document was accepted, subject to final review by the TF members after an updated version (Draft 2) sent out.
5. Next Steps The next steps for the WG P&P (Entity Method) are as follows: a) Approval by the TF b) Approval by Administrative Subcommittee c) Approval by Transformers Committee d) Approval by AudCom.
6. Adjournment The meeting adjourned.

Transformers Committee’s Entity Working Group Policies and Procedures for Standards Development
1.0 Introduction
Clause 1.0 through 1.5 shall not be modified except as follows: Where appropriate, replace shaded italics with the name of the Working Group and the name of the Sponsor. If the name of the Working Group is inserted only in the title (above) and at Clause 1.3, the Working Group will add the additional sentence shown in brackets, and replace [Working Group Name] in the remainder of the document with "the Working Group" or appropriate related form.
1.1 Role of Standards Development and these Procedures
This clause shall not be modified.
In today’s technological environment, standards play a critical role in product development and market competitiveness. In the IEEE, the responsibility for how a standard originates and evolves is managed by a Sponsor. It is essential in the management of a standard’s development to avoid any actions by the Sponsor or the participants that result in a violation of procedures. These procedures establish the necessary framework for a sound standardization process.
1.2 Conduct
This clause shall not be modified.
Meeting attendees and participants in standards activities shall demonstrate respect and courtesy toward each other and shall allow each participant a fair and equal opportunity to contribute to the meeting discussion. While participating in IEEE standards development activities, all participants, including but not limited to, individuals, entity representatives, entity members, entities participating directly in the entity process, and entities participating indirectly in the individual process shall act in accordance with all applicable laws (nation-based and international), the IEEE Code of Conduct, the IEEE Code of Ethics, and with IEEE-SA Standards Board Bylaws (see IEEE-SA Standards Board Bylaws Clause 5.2.1 on “Participation in IEEE standards development”) and IEEE-SA Standards Board Operations Manual.
A Working Group Chair that suspects persistent violation of these principles or standards by an individual shall refer the matter to the Sponsor.
1.3 Modifications to these Procedures
2
DRAFT 2 (final)
This clause shall not be modified, except to identify Working Group.
These Policies and Procedures outline the orderly transaction of business by all Entity Working Groups of the Transformers Committee, hereinafter referred to as “the Working Group”.
The Working Group may amend these procedures with the approval of its Sponsor. The Sponsor may modify these procedures. Modification in this context means that material in these procedures may be modified as long as that clause is not indicated as one that shall not be changed. The IEEE-SA Audit Committee (AudCom) strongly recommends that all subjects included in these procedures are addressed by the Working Group or Sponsor.
None of the rules or requirements in these policies and procedures may be suspended.
1.4 Hierarchy
This clause shall not be modified except to identify insert the name of the Sponsor.
Participants engaged in the development of standards shall comply with applicable federal, state, and international laws. In addition, for standards matters, the latest version of several documents takes precedence over these procedures in the following order:
New York State Not-for-Profit Corporation Law IEEE Certificate of Incorporation IEEE Constitution IEEE Bylaws IEEE Policies IEEE Board of Directors Resolutions IEEE Standards Association (IEEE-SA) Operations Manual IEEE-SA Board of Governors Resolutions IEEE-SA Standards Board Bylaws IEEE-SA Standards Board Operations Manual IEEE-SA Standards Board Resolutions Policies and Procedures of the Transformers Committee
Robert's Rules of Order Newly Revised (RONR) is the recommended guide on questions of parliamentary procedure not addressed in these procedures.
1.5 Fundamental Principles of Operation
This clause shall not be modified.
For the development of standards, openness and due process are mandatory.
3
DRAFT 2 (final)
Openness means that any entity, as defined in Clause 2.3, that has or could be reasonably expected to have a direct and material interest, and that meets the requirements of these procedures has a right to participate by:
a) Attending Working Group meetings (in person or via electronic means) b) Becoming a member of the Working Group c) Becoming an officer of the Working Group d) Expressing a position and its basis, e) Having that position considered, and f) Appealing if adversely affected.
IEEE due process requires a consensus of those parties interested in the project. Consensus is defined as at least a majority agreement, but not necessarily unanimity.
Due process is based upon equity and fair play. In addition, due process requires openness and balance (i.e., the standards development process shall strive to have a balance of interests and not to be dominated by any single interest category). However, for the IEEE Standards Sponsor ballot, there shall be a balance of interests without dominance by any single interest category.
1.6 Definitions
This clause shall not be modified except to include additional definitions.
Written communication includes but is not limited to meeting minutes, letter, email, and fax.
Sponsors of IEEE standards projects are committees that are responsible for the development and coordination of the standards project and the maintenance of the standard after approval of the standard by the IEEE-SA Standards Board. (IEEE-SA Standards Board Bylaws 5.2.2).
Responsible Subcommittee is an optional subgroup of the Sponsor with delegated responsibility for approving PARs and Sponsor ballots. Responsible Subcommittees assist the Sponsor committee in the control and management of a large scope of work involving multiple working groups. A PAR study group or a working group (WG) is not a Responsible Subcommittee.
In this document, the term “Sponsor” means the sole Sponsor, the Responsible Subcommittee, or in the case of co-sponsored projects, the primary Sponsor.
A participant is an individual or entity involved in the standards development process (see IEEE- SA Standards Board Bylaws Clause 5.2.1 on “Participation in IEEE standards development”).
NOTE: An entity participant can be a member or non-member of the IEEE-SA or working group.
NOTE: An individual participant can be a member or non-member of the IEEE or IEEE-SA.
A non-member is an entity that has not satisfied the criteria for membership defined in 4.1. 4
DRAFT 2 (final)
A member is an Advanced Entity Member of the IEEE-SA that has satisfied the criteria for membership defined in 4.1. A member is listed on the WG roster.
A Designated Representative (DR) is an individual designated by a member to represent the member in the Working Group. A Designated Representative Alternate (DRA) is an individual designated by a member to represent the member in the Working Group when the DR is not available.
A voting member is a member that has satisfied the criteria for voting membership defined in 4.1. A voting member can participate in working group motions and ballots.
A non-voting member is a member that has not satisfied the criteria for voting membership defined in 4.1.
An Entity Member Representative is an individual identified by the entity as responsible for managing the membership of that entity under the IEEE-SA Corporate program.
An observer is a non-member that is a Corporate Member of IEEE-SA, or an entity non-member of the IEEE-SA that has chosen to observe at most one meeting of the Working Group per project (see IEEE-SA Standards Board Bylaws Clause 5.2.1.2 on “Membership requirements for standards developed under the entity method”).
A technical expert is an individual who is invited by the WG to attend at most three meetings of the WG during the lifetime of a particular project (see IEEE-SA Standards Board Bylaws Clause 5.2.1.2 on “Membership requirements for standards developed under the entity method”).
A Sponsor Liaison is an individual appointed by the Sponsor to monitor the WG activities and report back to the Sponsor.
2.0 Working Group Responsibilities
2.1 Primary Responsibilities
This clause shall not be modified except to include additional responsibilities.
The Working Group shall:
a) Complete the project from Project Authorization Request (PAR) approval to IEEE-SA Standards Board approval as specified by the PAR, and in compliance with IEEE-SA policies and procedures. b) Use the IEEE Standards document template format or the applicable template for standards jointly developed with, or adopted from, another international standards organization. 5
DRAFT 2 (final)
c) Submit to the Sponsor any documentation required by the Sponsor, for example, a project schedule or a monthly status report. d) Notify the Sponsor of the draft development milestones. e) Notify the Sponsor when the draft is ready to begin IEEE Standards Sponsor ballot. f) Use the IEEE-SA approved tool for Working Group meeting registration. g) Use the IEEE-SA approved tool for creation and submission of Working Group rosters. h) Use the IEEE-SA approved tool for Web hosting of Working Group information. i) Only those authorized to access and use IEEE’s data, including personal data, from IEEE systems are permitted to do so, for the purposes intended, including to support the technical development work on the standard, and only in compliance with IEEE or IEEE- SA Privacy and data privacy policies.
2.2 Other Responsibilities
This clause may be modified.
The Working Group shall:
a) At the time of PAR submittal, provide a rationale for the development of the standard, explaining the needs for the standard and what the standard will fulfill for industry and the general public. b) Obtain funding to cover dedicated support from the IEEE-SA, when desired, to expedite the standards development process. c) Attend at least one meeting of the Sponsor per year and provide a report of the Working Group activities including the latest draft standard.
2.3 Working Group Constitution
This clause shall not be modified.
Each entity shall be an Advanced Entity Member of the IEEE-SA in order to be eligible for membership in the Working Group. There shall always be at least three members in the Working Group during the life of the project. For other information on participation in the Working Group, see Clause 5.2.1.2 on “Membership requirements for standards developed under the entity method” of the IEEE-SA Standards Board Bylaws.
No one individual can be the member representative for more than one entity except for a temporary proxy vote. Each Designated Representative (DR) or Designated Representative Alternate (DRA) member representative (see Clause 4.1) can make or second motions, except for the Chair (or presiding officer). A motion made by a DR or DRA representing one entity shall 6
DRAFT 2 (final) not be seconded by a DR or DRA representing the same entity. Each representative shall declare what entity he or she represents and that the representative’s voting shall be independent of any other entity.
The following qualify to become entity members of the Working Group: Corporation: A for-profit or not-for-profit entity that is not under the control, as defined in 5.2.1.2 of the IEEE-SA Standards Board Bylaws, of another entity and that is organized under articles of incorporation or similar legal structures. Limited Liability Companies are considered to be Corporations. Partnership: An unincorporated association of two or more individuals who are co- owners of a business. Sole proprietorship: An unincorporated business owned by a single individual. Government agency: An entity that is part of an executive, legislative, or judicial branch of a government and that has sufficient discretion in the management of its own affairs to distinguish it as separate from the administrative structure of any other governmental entity. Academic institution: An educational entity that, in addition to having a controlling body such as a Board of Regents or a Board of Governors, has sufficient discretion in the management of its own affairs to distinguish it as separate from the administrative structure of any other educational entity.
In the event that, through merger or acquisition or other similar event, an entity member of the IEEE-SA has its assets totally or substantially transferred to another entity, membership in the Working Group may be transferred to the new entity, provided that the new entity is not already a member of the Working Group.
3.0 Officers
This clause shall not be modified except to include additional officers.
There shall be a Chair and a Secretary, and there should be a Vice-Chair. The office of Treasurer is suggested if significant funds are involved in the operation of the Working Group and/or its subgroups, or if the group has multiple financial reports to supply to the IEEE-SA. A person may simultaneously hold the positions of Treasurer and another office, other than Chair.
Officers shall be representatives of Advanced Entity members of the IEEE-SA.
At the first organizational meeting, the Working Group shall elect its operating officers in accordance with the procedures of its Sponsor, and, where necessary, Robert’s Rules of Order.
3.1 Election of Officers
7
DRAFT 2 (final)
This clause may be modified.
The Chair or Sponsor designee shall appoint an Elections Administrator, whose function is to conduct an election. The Elections Administrator shall not be a nominee in the election and shall not vote in the election. An election will seek to fill offices that are either vacant, have an official in temporary appointment, when an officer’s entity affiliation has changed, or when the term of office has expired.
The Working Group members shall nominate to the Elections Administrator one or more member representatives for each office to be filled at the election. Nominees shall be eligible to hold the office, if and when they are elected (see Clause 3.0). A person shall be nominated for no more than one office, except in the case of Treasurer, as per Clause 3.0. The response period for nominations shall be at least 14 calendar days. If no nomination is received for an office, a temporary appointment shall be made in accordance with Clause 3.2.
The Elections Administrator shall conduct the election by letter ballot, electronic ballot, or a vote at a meeting. Voting will conclude no sooner than after 14 calendar days for a letter or electronic ballot. Each voting member shall cast a single election ballot. Within the ballot, the voting member may vote for multiple nominees for each office with the limit of one vote per nominee. The nominee with the greatest number of approval votes shall win the election, provided ballots are returned by a majority of the eligible voters for that election. If a majority of votes is not received, the ballot can be extended or a new ballot will take place. Any tie votes will be broken by a runoff ballot, where eligible voters may cast only one vote in the election.
The election of the Chair and Vice-Chair requires confirmation from the Sponsor. If the Sponsor does not confirm the Chair or Vice-Chair, another election will be run or the Sponsor will make a temporary appointment per Clause 3.2.
If any officer’s entity affiliation changes, that officer shall be subject to re-election by a majority of the members of the Working Group. If additional candidates are interested in serving in the officer role, they may run against the current officer at this time. The current officer continues to serve in his or her officer role until the close of the election. The election determines who will serve out the remainder of the existing term of office.
3.2 Temporary Appointments to Vacancies
This clause may be modified.
If an office other than the Chair is vacant for any reason (such as resignation, removal, lack of nomination at an election), a temporary appointment shall be made by the Chair for a period of up to 12 months. In the case of Chair, the Sponsor shall make the temporary appointment, with input from the Working Group.
3.3 Removal of Officers
8
DRAFT 2 (final)
This clause may be modified.
An officer may be removed by approval of two-thirds of the voting members of the Working Group meeting in Executive Session, or in accordance with the procedures of the Sponsor. The officer suggested for removal shall be given an opportunity to make a rebuttal prior to the vote on the motion for removal. Removal of the Chair requires affirmation by the Sponsor.
3.4 Responsibilities of Working Group Officers
This paragraph shall not be modified.
When carrying out the duties of an officer described in IEEE’s policies and procedures, officers of the Working Group:
a) shall not act: 1) in bad faith; 2) to the detriment of IEEE-SA; 3) to further the interest of any party outside IEEE over the interest of IEEE; or 4) in a manner that is inconsistent with the purposes or objectives of IEEE; and b) shall use reasonable efforts to ensure that participants of the Working Group conduct themselves in accordance with applicable policies and procedures including, but not limited to, the IEEE-SA Standards Board Bylaws clause on “Participation in IEEE standards development.” (See Clause 1.2.)
The officers of the Working Group shall manage the day-to-day operations of the Working Group. The officers are responsible for implementing the decisions of the Sponsor and managing the activities that result from those decisions.
The remainder of this clause may be modified to include additional officers and their responsibilities.

11
DRAFT 2 (final)
The Working Group is responsible for its finances; therefore, an officer of the Working Group shall perform the responsibilities of the Treasurer. If there is a Treasurer, this clause may be modified to include additional responsibilities.
If the funds are minimal and transactions not complicated, the officer position of Treasurer is not required and can be assumed by one of the other officers. In this case, the responsibilities a) to d) below shall be added to the responsibilities of either the Vice-Chair (3.4.2), or Secretary (3.4.3) (e.g., if Clause 6.3 Meeting Fees remains in use). If there are no funds the clause is not required, and the text below shall be removed and replaced with the words “Not applicable.”
Not applicable
4.0 Working Group Membership
4.1 Obtaining Membership in a Working Group
This clause shall not be modified, except to address the shaded text.
Working Group membership is by entity. A member shall be an Advanced Entity Member of the IEEE-SA.
A non-member may become a member only after:
● providing contact and representative (DR/DRA) information needed for the roster (see Clause 4.7), ● paying any services fee
A non-member becomes a non-voting member by attending one meeting.
A non-voting member becomes a voting member by attending 2 of the last 3 meetings and upon sending a request for voting status to the Working Group chair prior to the next meeting. The member’s voting status will be effective at the start of the next meeting.
Voting membership is granted to those entities attending the first meeting of a newly chartered Working Group upon their request to the Working Group chair.
4.2 Attendance at Meetings
This clause shall not be modified, except to address the bracketed text.
Representatives of an entity must attend at least 50% of a meeting’s duration as stated in the approved agenda and satisfy the requirements of Clause 6.3 regarding any registration fee for the meeting for that attendance to count towards gaining or maintaining voting membership.
12
DRAFT 2 (final)
This is called “credited attendance” in order to distinguish it from attendance that does not satisfy these criteria.
Attendance at a meeting via teleconferencing or electronic means, e.g., Internet conferencing, shall count towards the attendance requirements.
4.3 Entity Representatives
This clause shall not be modified.
A member shall have one DR and may have more than one DRA participating in the Working Group. The Entity Member Representative of the entity determines the DR and DRA(s) for the Working Group. The assignment of a DR or DRA can change throughout the life of the Working Group.

16
DRAFT 2 (final)
While having a balance of all interested parties is not an official requirement for a Working Group, it is a desirable goal. As such, the officers of the Working Group should consider issues of balance and dominance that may arise and discuss them with the Sponsor.
Participants shall be asked to state their employer and affiliation at each Working Group meeting as required by the IEEE-SA Standards Board Operations Manual clause 5.1.2.3 on “Disclosure of affiliation”.
All IEEE Standards development meetings are open to anyone who has a material interest and wishes to attend subject to the provisions of Clause 4.1;however, some meetings may occur in Executive Session (see Clause 6.2).

Unless otherwise approved by the Sponsor, a quorum shall be defined as one-half of the Working Group members (i.e., the DR or DRA of each entity).
6.2 Executive Session
This clause shall not be modified.
Meetings to discuss personnel or sensitive business matters (e.g., the negotiation of contracts), or for other appropriate non-public matters (e.g., the receipt of legal advice), may be conducted in Executive Session.

This clause shall be included and shall not be modified.
Members of the Working Group may employ proxy voting only when other methods of participation have been exhausted. Each appointment of a proxy shall be sent to the Working Group Chair and the member serving as the proxy via fax or written communication that contains the signature of the member appointing the proxy (an email is acceptable.) A proxy shall not be valid without written acknowledgment from the Working Group Chair and the member serving as proxy of receipt of the appointment. Members serving as proxies shall inform the Chair of their proxy prior to the start of the meeting in which the proxy is to be in effect.
Any one member of the Working Group may hold no more than two proxy votes in addition to his or her vote.

Communications shall be in compliance with the Sponsor’s communication requirements.
9.0 Appeals
This clause shall not be modified.
Any person dissatisfied with a technical decision shall follow the approved procedures for providing technical input to the Working group, including but not limited to presenting the concern to the Working Group, and making a technical comment during the applicable comment submission and/or balloting period.

Minutes of the Meeting of the IEEE PES Transformers Committee Task Force on Revision of the Working Group Policies and Procedures
Meeting Date: March 8, 2019 Meeting Time: 1:30 PM – 2:15 PM EST Meeting Location: GoToMeeting Conference Call Members Present: Bruce Forsyth (Chair), Jim Graham, Peter Balma, David Wallach Sue McNelly (ex-officio) Members Absent: Kris Zibert, Chuck Johnson, Steve Shull
1. Welcome and Attendance The Chair opened the web meeting by welcoming the Task Force members and taking attendance. There were 6 of the 8 members on the call so a quorum was present.
2. Results of TF Vote 1 of the Individual and Entity WP P&Ps
After the conclusion of Meeting 3 the documents developed during Meeting 3 (Draft 3a of the Individual WP P&P and Draft 3 of the Entity WG P&P) were sent electronically to the TF members for review and vote for approval or rejection. The results of TF Vote 1 were as follows: WG P&P (Individual Method) – Draft 3a: Approved = 5 (65.5%) Disapproved = 3 (37.5%) The disapprovals were based primarily on a desire to strengthen the membership requirement. WG P&P (Entity Method) – Draft 3: Approved = 6 (75%) Disapproved = 2 (25%) The disapprovals were based primarily on a) a desire to clarify the form of the document to be provided, and b) reinstating the Treasurer’s duties.
The Chair reviewed the comments received and developed revised wording in an effort to address the negative votes and sent the revised proposals to the TF in the form of two separate vote forms. Vote 2 addressed issues related to the Individual Method WG P&P and Vote 3 addressed issues related to the Entity Method WG P&P. The results of Votes 2 and 3 are listed in the following sections.

The Working Group Chair may choose to end consideration of new voting member requests if the document is substantially complete and expected to be approved by the WG for sponsor ballot within 2 meetings. The decision to end consideration of new voting member applications shall be announced at a Working Group meeting, documented in the meeting minutes, and shall not be made in an effort to specifically deny any particular person or company participation in the development of the document. The member’s voting status will be effective at the start of the next meeting. Voting membership is granted to those participants attending the first meeting of a newly chartered Working Group upon their request to the Working Group Chair.
Approved = 4 (50%) Disapproved = 3 (37.5%) No Response = 1 (12.5%)
After a lengthy discussion related to balancing the principle of openness in standards development and the desire to limit late changes to voting membership, the following language was unanimously accepted:

Appendix A Vote #2 and Vote #3 Full Text
TF on Revision of WG P&P (Individual Method)
VOTE #2 Item 1: Revision of Clause 3.2 A proposal to modify Clause 3.2 has been made to eliminate references to elections. New proposed language (changes shown in blue): 3.2 Temporary Appointments to Vacancies This clause may be modified. If an office other than the Chair is vacant for any reason (such as resignation, or removal, lack of nomination at an election), a temporary appointment shall be made by the Chair for a period of up to 12 months. In the case of Chair, the Sponsor shall make the temporary appointment, with input from the Working Group. An appointment or election for the vacated office shall be made in accordance with the requirements in Clauses 3.0 and 3.1 at the earliest practical time.
Item 2: Revision of Clause 4.1 A concern was raised during the first TF vote on the IND WG P&P that “tighter” language is necessary in clause 4.1 to prevent people from automatically being granted WG membership by attending 2 meetings in a row when the document is substantially complete. There are concerns that such automatic membership could be used to gain voting privileges without participating in the substantial development of the document, and some people consider that inappropriate. However, restricting membership goes against the openness principle of the IEEE standards development process and is likely to be challenged unless guidelines are in place to prevent abuse by WG Chairs. The new language shown in blue is offered as a suggestion to provide the WG Chair some discretion with regard to granting voting membership and also provide guidelines for the use of such discretion. New proposed language (changes shown in blue): 4.1 Obtaining Membership in a Working Group This clause may be modified. Working Group participation and membership is on an individual basis (i.e., regardless of affiliation). A participant becomes a voting member by attending 2 of the last 3 meetings and upon sending a request for voting status to the Working Group Chair prior to the next meeting. The Working Group Chair may choose to end consideration of new voting member requests if the document is substantially complete and expected to be approved by the WG for sponsor ballot within 2 meetings. The decision to end consideration of new voting member applications shall be announced at a Working Group meeting, documented in the meeting minutes, and shall not be made in an effort to specifically deny any particular person or company participation in the development of the document. The member’s voting status will be effective at the start of the next meeting. Voting membership is granted to those participants attending the first meeting of a newly chartered Working Group upon their request to the Working Group Chair.
Page 1 of 1 TF on Revision of WG P&P (Entity Method) VOTE #3 Item 1: Revision of Clause 2.2.c: A suggestion has been made to clarify the format of the copy of the latest draft standard to be provided. New proposed language (changes shown in blue): c) Attend at least one meeting of the Sponsor per year and provide a report of the Working Group activities including an electronic copy of the latest draft standard in one of the following formats: PDF, DOC, DOCX, TIFF, or JPG.
Item 2: Revision of Clause 3.4.1.q: As in 2.2.c, a suggestion has been made to clarify the format of the copy of the information to be provided. New proposed language (changes shown in blue):
q) Forwarding all Working Group meeting minutes and draft documents to the Sponsor in an approved electronic format (PDF, DOC, DOCX, TIFF, or JPG) and reporting all meeting activities to the Sponsor Liaison within 15 days of the meetings.
Item 3: Revision of Clause 3.4.4: A suggestion has been made to reinstate the Treasure responsibilities. During our previous TF meeting we discussed the guidance language in the second paragraphs that states “If the funds are minimal and transactions not complicated, the officer position of Treasurer is not required and can be assumed by one of the other officers.” On the assumption that the funds are minimal we chose to make the Treasurer position “not applicable.” However, the assumption that the funds will be minimal may not be appropriate. The safe approach is to reinstate the original language. New proposed language (changes shown in blue): The Treasurer shall: a) Maintain a budget, if applicable. b) Control all funds into and out of the Working Group’s bank account, if applicable. c) Follow IEEE policies concerning standards meetings and finances. d) Ensure that the Sponsor adheres to the IEEE Financial Operations Manual and the Annual Financial Report clause in the IEEE-SA Standards Board Operations Manual. e) Be familiar with relevant training materials available through IEEE Standards Development Online.
Page 1 of 2 TF on Revision of WG P&P (Entity Method) Item 4: Revision of Clause 6.0: The first paragraph of Clause 6 has a statement that allows 15% of the voting members to call a meeting. This is consistent with the corresponding clause in the Individual WG P&P, but since the minimum membership for entity WGs is 3, this could allow 1 entity member to call a meeting, although it is acknowledged that a quorum would not be present, and no decisions could be made. It has been suggested the value of 15% be increase to 40%. New proposed language (changes shown in blue): Working Group meetings may be conducted either exclusively in-person or in-person with one or more participants contributing via electronic means, or exclusively via electronic means. Working Group meetings shall be held, as decided by the Chair, or by petition of 15 40% or more of the voting members, to conduct business. This may include making assignments, receiving reports of work, progressing draft standards, resolving differences between subgroups, and considering views and objections from any source.

A.1.5 Chairman’s Remarks The Chair recommended that anyone interested in PAR preparation process should attend the new Monday more session on this topic.
A.1.6 Status of Bushing Standards The Chair presented the Standards Status Report for bushings, see Appendix A. The Chair reminded the attendees that they can review and submit comments to any of WG Chair even if the document is not currently open for revision. The WG Chair should save any comments received for review during the next revision cycle of their documents.
The Chair noted that timing with 19.02 will be critical to include this new bushing standard into 19.00 within the current revision cycle.
With the IEEE policy changes for dual logo documents changes may need to be incorporated into 65700-19-03 in this regard as it is due to expire in 2024 and should be starting a new revision cycle soon.
A.2 Working Group and Taskforce reports
A.2.1 PC57.19.00-2004 – Peter Zhao, Chair; Eric Weatherbee, Secretary See complete WG minutes in Appendix B of this report.
A.2.2 C57.19.100-2012 – Tommy Spitzer, Chair; Jeff Benach, Secretary . See complete WG minutes in Appendix C of this report.
A.2.3 WG PC57.19.01-2017 – Dr. Shibao Zhang, Chair; David Wallach, Secretary Page 1 of 15
Annex A
Dr. Zhang stated he will seek feedback starting in 2020 and plans to start work on the next revision cycle of the document in 2021 if any revisions are needed with a Draft target completion date of 2026. No meeting held as the latest revision was published July 2018.
A.2.4 WG PC57.19.02 Distribution Transformer Bushings – Ed Smith, Chair; Steven Shull, Vice Chair Mr. Shull stated that progress within the WG is proceeding at a good rate, the base document is complete, and the work is now focusing on the technical information. Bushings rated 1kV and below do not fit well in 19.00 in its current state and will require some additional details to be worked out with 19.00 WG. The Chair asked if extra coordination will need to be done with 19.00 because if their document is not completed by 2020 it may not allow enough time to be included in this revision cycle of 19.00. Mr. Shull stated their WG believes they will reach completion of the draft by the end of 2020. See complete WG minutes in Appendix D of this report.
A.2.5 WG C57.19.04-2018 – Scott Digby, Chair; JD Brafa, Vice Chair; Rich vonGemmingen, Secretary Mr. Digby stated he currently is working with the 19.00 WG to incorporate 19.04. No meeting was held as the document was published June 2018.
A.2.6 IEC/IEEE 65700.19.03 – Les Recksiedler (IEEE) and John Graham (IEC, retired), Co-Chairs Mr. Recksiedler stated he plans to hold the first meeting for the next revision cycle of the document at the Fall 2019 meeting. Anyone wishing to contribute should plan to attend this meeting. Mr. Recksiedler stated he will contact the IEC Co-Chair to see if he will be able to work on the document and will investigate if any additional revisions will be needed to be in-line with current IEEE policy for dual logo documents. The first dual logo bushing standard was approved June of 2014, as such, no meeting was held.
A.2.7 TF Bushing Overload – Matthew Weisensee, Chair; Alwyn VanderWalt, Secretary Mr. Weisensee stated that the TF has completed the scope of work assigned by the SubCom. The TF has found the available information in C57.19 standards and guides are not sufficient to address the needs of the users. The Chair asked that the TF provide a document stating what standards and guides they have reviewed and what their conclusions are. The new technologies are not covered and only OIP designs addressed with 2 times rated current with 150°C hot spot and 40°C air with 110°C oil temperature is not acceptable by any of the four bushing manufacturers in attendance. The Chair would like the TF to provide this document and include recommendation on how to utilize their findings. If this cannot be completed by 2020 we may need to include a note similar to what Dr. Zhang provided to C57.91. The Chair asked Dr. Zhang to send this information to Mr. Weisensee and Mr. Spitzer. See complete minutes in Appendix E of this report.
A.3 External Liaison Reports A.3.1 IEC Bushing Standards Activity – Bruno Mansuy, IEEE/IEC Liaison See complete report in Appendix F of this report.
A.3.2 IEEE 693 – Eric Weatherbee, IEEE Liaison Mr. Weatherbee informed the SubCom that 2018 version of the standard was published February 2019. A.3.3 WG PC57.160 Guide for PD Meas. in Bushings and Inst. Trans. – Thang Hochanh, Chair No meeting was held due to the status of the document. The guide is currently in process of going to Ballot.

A.4.1 Dielectric Frequency Response (DFR) Test for Bushings, C57.12.200
The Chair asked Ms. Zaman if she could provide a brief update to the SubCom on the first meeting held during an IEEE Conference for this TF for Entity Ballot Oversight . Mr. Zaman stated the next meeting will take place in China this July. They accepted 4-5 new technical experts. Dr. Zhang stated he had attended the meeting but was confused as to what the actual purpose/goal of the guide was. Ms. Patel, the IEEE co-Chair, stated the WG Chair is new to IEEE and is becoming familiar with the proper administrative functions and will provide a scope and purpose prior to the next meeting.
A.4.2 CIGRE Reference 755, Transformer Bushing Reliability, WG A2.43
Mr. Durand Stacy provided detailed information on what topics are included in the CIGRE document as Mr. Geibel was not in attendance.
A.5 New Business
A.5.1 PC57.165 Temperature Measurement
The Chair stated that this WG is looking for experts to provide feedback on bushing temperature measurement. The WG provided a document with proposed sections they believe are relevant for this topic, see Appendix G of this report.
Dr. Zhang asked when are they wanting to perform the temperature measurements? One of the WG members clarified that it is for online monitoring by the users in the field. They are not bushing experts, so they are trying to determine if it is worthwhile to do, and how do it if it is. The Chair asked for volunteers, Mr. Les Recksiedler, Mr. Sanjib Som, Mr. Ajith Varghese and Mr. Thompson agreed to provide information to the WG. Mr. Recksiedler agreed to coordinate the groups effort and provide feedback prior to the F19 meeting.

B.1 Chair’s Remarks
The Chair briefly highlighted the requirement that while introducing one need to state their employer/ company and sponsor if the difference from the company. The chair also reminded that IEEE and transformer committees are non-commercial organizations and standards shall focus only on developing performance and functional requirement and not design and construction details.
The Unapproved minutes from the Fall 2018 meeting and the agenda for Spring 2019 meeting was sent out to members and guests 14 days before the Spring meeting in Anaheim, and it’s also posted on the website.
An area that WG and TF have been late with and we need to improve is to send out the Agenda at least 14 days before the meeting. This also applies to on-line WG and TF meetings.
All TF and WG MUST record the attendance in the AM System- The WG/TF minutes do not need to include the list of attendees. The Roasters circulated in the meetings should not have the email addresses included to follow the data privacy policy. WG/TFs are urged to keep website information current. Any presentation presented during the meetings should be posted
All attendees should have updated information, such as email address in the AM system, as for all correspondence, this system is used.
The Chair reminded the WG and TF leaders to submit their minutes from the meetings within 15 days to the SC chair and secretary. The SC Secretary then has to submit the SC minutes within 45 days of the SC meeting. To minimize revision and errors in the sub-committee level and transformer committee level minutes, please send the final version of your minutes.
The Chair reminded WGs that call of the patent is required a during every WG meetings including on- line/Teleconference meeting. If there are any patent claim, it shall be noted but not discussed at the working group meetings. Calls for Patents is not required for TF.
Page 1 of 25 Per new guidelines from IEEE, Audio/Video recording or photography is not allowed during SC, WG and TF meetings. The secretary could record the meeting for writing the minutes of meetings but this needs to be notified, and recording must be deleted after the use. The subcommittee Secretary would be recording the audio of the SC meeting for this reason today.
The Chair informed that there are changes to copyright policy – Clause 7 of IEEE standards Boards bylaws and Clause 6.1 of IEEE-SA Standards board operation Manual. There will be two webinars in April with more information.
Sue McNelly is in a process to update the IEEE transfromer committee website. The new web.layout will be rolled out in about 2 weeks. Once the website is transitioned please make sure all the relevenat documewnts have been transistioned for your TF/WGs. Please contact Sue if something is missing. This goes also for presentations.
Some of WG/TG were late in sending the agenda for the spring meeting. The invitation with agenda should be sent out 14 days before the meeting. Its required for the meeting conducted offsite or online/Teleconference as well. Agenda shall include more details of topics that will be discussed so invitees can decide whether to participate on not.
The Chair shared details of upcoming PES sponsored meeting as well as details of next transformer committee. The fall committee meeting 2018 will be held in Columbus, Ohio on the 27th -31st of October 2019. Spring meeting 2020 will be held in Charlotte, NC on the 22nd -26th of March 2020.

The Chair moved on to the Old Business.
The Chair proposed the following definition that he displayed on the screen: Low Frequency Dielectric Test:
Dielectric tests in which the test voltages are alternating voltages with frequencies less than 500 Hz from an external source.
The Chair entertained a motion to adapt the above proposed definition.
The motion was approved to use Low Frequency Dielectric Test: Dielectric tests in which the test voltages are alternating voltages with frequencies less than 500 Hz from an external source as a definition for low frequency dielectrics test (1st approver: John Foschia and 2nd approver: Sen Cihangir).
The Chair showed the basic outline and approach he received from Dave Giebel and generally agreed upon without any verbal objections. This outline will be used in writing the guide. Phil Hopkinson asked what the scope of this guide is supposed to be. The Chair clarified that this guide will provide guidelines for any low frequency test defined in the test code.
There was a discussion on which tests to be included in this guide. Induced voltage test with PD measurement, applied voltage test, and power factor test with capacitance measurement were suggested to be included in this guide.
Xavier Artega asked the question on whether or not auxiliary equipment such as CT testing should be included. Jeff Britton recommended to only include the tests that raise questions amongst manufacturers
Page 4 of 25 and end users that this guide can help with. The Chair will start with induced and applied tests for the development of this guide.
Don Platts mentioned that the reason for this guide was to move all tutorial material from standards to this new guide.

Meeting Attendance The working group met at 9:30am. There were 118 attendees and 18 members present. Quorum was achieved at 62.1%. Discussions · Motions were made to approve the minutes of the Fall 2018 WG meeting (D. Gross, A. Winter) and the agenda of the Spring 2019 meeting (D. Gross, A. Winter) and both were unanimously approved. · No essential patent claims were brought to the working group’s attention. · A request was made for the title and scope of the working group to be included in the minutes. o The PAR details which include both the title and scope of the working group are included as an attachment to the minutes. · The chair reviewed the title and scope of the working group. o UHF and other PD measurement methods cannot be included in this guide due to the scope, however it may be possible to include UHF methods as an annex. o The current PAR expires in 2021. · D. Gross gave a presentation regarding partial discharge which included recommendations for revisions to the guide. o Section 4 - Change of the coupling capacitor abbreviation ‘Ck’to ‘Cc’. o Section 4.2 – With the appropriate quadrupole, smaller values of coupling capacitance than presently stated become feasible. o Section 4.4.1 - Modify/remove the frequency band limits. o Section 4.4.2 - Add the pulse train response graph from IEC 60270. § The chair noted that permission from IEEE must be obtained before including any graphical materials from outside sources. o Section 4.4.2 – Remove the note regarding deviations of pulse train response; all modern PD measurement equipment incorporates this. o Section 4.4.3 – Add more information regarding parallel acquisition. o Section 4.4.5 – Add note regarding calibrations at noise levels close to the new floor because of ‘fake linearity.’ o Investigate calibration response criteria alignment with IEC. IEC allows for a 3% deviation of calibration response where IEEE allows for 5% deviation. o Remove references of scale factor references – possibly remove the entire paragraph. · D. Gross recommended the addition of information regarding phase resolved patterns to an appendix. · R. Kuppuswamy recommended the addition of information regarding the measuring impedance. o It was noted that: § Measuring impedance is a critical component of the measurement circuit. § Tests can inflict damage to the measuring impedance. § Multiple concepts of measuring impedance are applicable. o R. Kuppuswamy volunteered to provide information to A. Kraetge for revisions to section 5.
Page 6 of 25 · D. Gross gave another presentation regarding partial discharge patterns and the basic physics regarding partial discharge. o It was recommended to include information of the cross-calibration matrix into the guide. The chair noted that this is not included within IEC and that the 2010 revision of the guide did not support inclusion of this information. · It was recommended to include requirements regarding the noise floor limits as well as measurements on all external terminals of the transformer. o The membership noted that these requirements would be a component of the test code standards and that the requirements are not within the scope of the guide. · The vice-chair noted that within Annex F, it is recommended to include information regarding the noise generated in power electronics because of their prevalence within the industry. · R. Kuppuswamy noted that the current annexes do not include ‘PD fingerprints,’ and recommended the following: o There is a need to recognize the ‘cross-talk’ between phases. o Reword Annex F to ‘Visual Recognition of PD Patterns.’ There was no motion. · Consensus within the working group supported PD patterns being supplied from users and not specific instruments or instrument suppliers. o The chair requested that users provide patterns to enrich Annex F.
Upon request from the WG, a word document of the present guide has been circulated.
Adjournment A motion to adjourn the meeting was made by D.Gross and seconded by D. Wallace. The meeting was adjourned at 10:45am.

Meeting Attendance The working group met at 1:50pm. There were 149 attendees and 33 members present. Quorum was achieved at >97%.
Discussions A larger room will be requested for the next meeting, based on Spring 2019 attendance. The chair presented the reasons that justify the use of the beta as an indicative information due to the facts below: · For beta below 5%, the correction factor to the peak wave value is minimal. (beta is the difference between the base curve/high frequency removed measured curve) · For beta at 10% or up to 30%, as shown on example on projector, the correction is also minimal, due to the fact that the frequency related to this example is lower than 200 kHz. · Any correction or k-factor is directly dependent of the frequency of the first oscillation (as stated in IEC 60060-1). · For a manufacturer test lab, when a test curve has a first pulse frequency high to very high, the correction will be high and for a beta-prime of 30% and a frequency of 1 MHz, the correction is up to 50% of the beta-prime value. o In this case the test lab will have the incentive to adjust the wave form to reduce the beta value. o When the impulse circuit is optimal, the first pulse frequency is usually low, i.e. well under 500 kHz and the correction is far under 50% (as presented to the WG). o The chair provided examples of full wave impulse shots with beta values less than 10% and greater than 30%. · The WG have discussed about the k-factor and the chopped waves. The chair mentioned that in IEC 76-4, the problem was solved when the charging voltage is adjusted to 110% of the 100% Full wave. · Pierre Riffon mentioned that provisions in the Standard has been provided to take in account high values of T1 (virtual front time).
New Business · In situations where a chop wave is applied without a previous full wave, what method is the peak of the chop wave to be measured and reported? (Jim McBride, JMX) o This could be addressed within WG C57.98 and will be discussed at the next meeting. There was no concern voiced regarding the use of peak voltage measurement in this specific situation. · The guide should make clear that waveform comparisons are to be made on the recorded traces and not the corrected traces. o This may not be clear in the standard and it should specifically refer to the recorded trace being used for waveform comparison. · The chair proposes that the beta values be provided on report screens, and also that an identification of ‘K-factor’ utilization should be provided on the reports.

Page 13 of 25 B.3.4 TF on Revision of Impulse Tests Pierre Riffon, Chair; Daniel Sauer, Vice-Chair
The TF met on March 26, 2019, from 4:45 pm to 6:00 pm. Twenty (20) members and twenty-eight (28) guests attended the meeting. Four (4) guests requested membership. The meeting was chaired by Pierre Riffon, Chair of the TF. Mr. Daniel Sauer was the vice-chair.
Meeting has been called to order by the Chair at 4:45 pm.
Attendance has been recorded in the AM system.
Required quorum was not met, presence of at least 22 members was required. The TF membership roster has been reviewed after the Jacksonville meeting and members who did not attend the last three meetings have been moved as guests. Guests who have not attended the last five meetings have been removed from the TF roster. 94 guests have been removed from the TF roster.
Because of the lack of quorum, the meeting agenda and the Jacksonville meeting minutes have not been approved. Approval by Email will be done.
The first item of business was related to a proposal of modifications to clause 10.3.2.1 of C57.12.90 concerning the condition of tertiary and stabilizing winding terminals during lightning impulse tests. This proposal was already surveyed within the TF membership and guests with an approval rate of 100%. The proposal was now surveyed within the Dielectric Tests Subcommittee and got an approval rate of 98.7%. Comments received have been presented and discussed during the meeting and it was no objections to the TF Chair observations made on these comments.
The second item of business was related to a proposal of modifications to clause 10.2.4 of C57.12.90 concerning the tap changer position during switching impulse tests. This proposal was already surveyed within the TF membership and guests with an approval rate of 92.9%. The proposal was now surveyed within the Dielectric Tests Subcommittee and got an approval rate of 96.5%. Comments received have been presented and discussed during the meeting and it was no objections to the TF Chair observations made on these comments.
Since the quorum was not achieved and that both proposals were approved by a large majority of Dielectric Tests SubCommittee members and guests who reply to the survey, the final wordings will be sent to the Dielectric Tests SubCommittee Chair for transmission to Steve Antosz for inclusion in the next draft of IEEE C57.12.90.
The meeting adjourned at 5:30 pm on March 26, 2018.
The next meeting is planned to be held in Columbus, Ohio on October 29, 2019.

*************************************************
Page 14 of 25 Following text will be sent to Steve Antosz for inclusion in the next IEEE C57.12.90 draft once the minutes and agenda is approved. 10.3.2.1 Terminals not being tested
Neutral terminals shall be solidly grounded. Line terminals, including those of autotransformers and regulating transformers, shall be either solidly grounded or grounded through a resistor with an ohmic value not in excess of the values given in Table 3.
Tertiary winding terminals shall be considered as line terminals.
When buried stabilizing winding terminals have been temporarily brought out of the tank for testing purposes only, they shall be connected the same way as they will be in service during impulse tests (grounded or in open circuit).
When a stabilizing winding terminal is brought out of the tank for grounding purposes, this terminal shall be grounded during impulse tests.
When stabilizing winding terminals are brought out of the tank for the purpose of grounding the winding and closing the delta, these terminals shall be connected as intended for service during impulse tests.
Table 3 —Grounding resistor values
Nominal system voltage (kV) Resistance (Ω)
345 and below 450
500 350
765 300
NOTE—These values are representative of typical transmission-line surge impedances.
The following factors shall be considered in the actual choice of grounding for each terminal:
a) The voltage to ground on any terminal that is not being tested should not exceed 80% of the full-wave impulse voltage level for that terminal.
b) When a terminal has been specified to be directly grounded in service, then that terminal shall be solidly grounded.
c) When a terminal is to be connected to a low-impedance cable connection in service, then that terminal shall be either directly grounded or grounded through a resistor with an ohmic value not in excess of the surge impedance of the cable.
d) Grounding through a low-impedance shunt for current measurements may be considered the equivalent f a solid ground.
As well as the following text
10.2.4 Tap connection The choice of the tap connection shall follow the following rules: · The tap position shall be selected in order to induce, as close as possible (preferably within ±3%), the rated switching impulse withstand voltage value on the LV winding terminal.
Page 15 of 25 · If the LV winding has no rated switching impulse level, the tap position shall be selected in order to induce, as close as possible (preferably within ±3%), 83% of the LV winding rated BIL value on LV winding terminal.
It should be noted that for some cases, the LV winding may receive a voltage which is less than its rated switching impulse level, or 83% of its rated BIL and, this shall be accepted. It should be also noted that for some other cases, the LV winding may receive a voltage which is higher than its rated switching impulse level, or 83%of its rated BIL, this shall be accepted and the transformer shall be designed for it. For transformers having a preventive autotransformer, the tap changer shall be in a bridging position, if this operational mode is permitted for continuous operation.

a. Clarification of measuring voltage during low frequency dielectric tests – Bertrand Poulin
A brief background on this topic was provided during the meeting. It was stated that Bertrand Poulin has not yet drafted a proposal and that no further action has been taken.
b. Class I Partial Discharge Testing – Don Ayers A brief background on this topic was provided during the meeting. A motion was made during the Spring 2018 meeting by Don Ayers to form a task force to revise the test procedure, test levels, and acceptance limits for partial discharge testing of Class I transformers. The motion was seconded by Mickel Saad. The meeting time expired and the motion discussion was tabled until the Fall 2018 meeting. Don Ayers was not present at the Fall 2018 meeting, so the motion continued to be tabled until this meeting. Don Ayers recommended that we form a Task Force to revise the test procedure, test levels, and acceptance limits for PD testing of Class I transformers. The floor was opened for discussion, based on the motion previously presented. There were questions about whether there is sufficient experience for Class 1 tranformers within the TF to develop this scope of work.
The chair requested a vote on the motion, the results of which are provided below:
19 Approved 0 Disapproved 9 Abstentions
The motion passed. There will be further discussion on how to involve the Distribution Transformer Subcommittee in this work.

1) Meeting called to order at 3:15 PM.
a. Welcome and Chair’s Remarks
2) Circulation of Attendance Sheets
a. 97 Attendees were present (54 Guests)
b. 43 of 53 Members present (quorum was achieved)
3) No essential patent claims made
4) Approval of Agenda (motion by Pierre Riffon and 2nd by Deepak Kumaria) and meeting minutes from Fall 2018 (motion by Klaus Pointner and 2nd by Akash Joshi) without objection.
5) Status of Current Draft and Comments – Jim McBride a. The present draft of the Guide is posted on the Working Group website
b. Review of C57.142 Draft 6 – The Chair noted that editorial changes continue, but the WG members and guests have not provided many comments since Draft 5. Some additional editing / cleanup may be needed and continued review by the WG is appreciated. Additional examples are included in D6 (GSU in backfeed mode, failing autotransformers, instrument transformers, and reactor switching).
c. The chair requested that the members and guests please continue to review and comment on the existing draft over the next few weeks before the draft is handed to the IEEE Switchgear Committee for review.
6) Status of Task Force Paper – Jim McBride a. IEEE requested the TF paper be reformatted to include CV’s for the paper authors. This will be handled by WG Vice Chair Xose Lopez-Fernandez.
7) Mitigation Methods Task Force Update – Phil Hopkinson
a. In the past, EHV reactors that were failing in the field were passing factory test levels. Special Terminated Lightning Impulse Tests (STLI) were then incorporated and failures reduced dramatically.
b. Phil requested manufacturers data using RSG (recurrent surge testing) in order to understand the stresses on windings. Phil reminded the WG that many old
Page 20 of 25 transformers had electrostatic shields. Line shields increase series capacitance and greatly reduce capacitance to ground. In the past (for 34.5 kV and below) static shields added to the winding seemed to increase probability of surviving re-strikes
c. Shielding solves many issues with series resonance and is relatively easy to apply. The conclusion is that increasing the series capacitance and reducing the capacitance to ground should improve the design. Phil urged the group to focus on improving transformer designs and developing new test methodologies.
d. Mitigation methods with some success have included: higher BIL, open terminal special impulse test, and fast-front switching surge with a long tail time.
e. The Chair added that more communication is required between the end-user of the transformer and the manufacturer with regard to the potential for exposure to high-energy transients in the field. Advanced modeling will be necessary in order to mitigate these issues. Experts who can model/analyze disc and layer winding designs are necessary in order to move the WG efforts forward. Multiple mitigation methods are also being discussed and will be addressed in the Guide.
8) STLI Presentation by Mike Spurlock of AEP (will be posted on the WG website) using standard impulse waveforms (1.2 x 50 us)
a. Pierre Riffon asked if arrestors are used in the testing (on the X terminal) and if full voltage is applied on the H terminal. No arresters were used and full voltage was applied. b. Phil Hopkinson commented there was significant focus on the current traces in the presentation, but pointed out some significant collapse on the non-impulsed terminals. The chair commented that the significant point is how quickly the voltage appears on the non-impulsed terminals and that the arrestors are clamping.
c. Mike Spurlock added that the manufacturers tests show the stresses are higher and deeper into the winding than a standard impulse test. The chair added the STLI test better represents how the transformer is connected in service. Phil agreed this assessment matches prior failure modes and mitigation. Discussion by Amitabh Sarkar and others ensued regarding various testing arrangements (open versus terminated windings for example).
d. Manush Safar asked a question regarding whether an opening breaker versus closing breaker scenarios have been investigated and included in the Guide. Phil commented that different phenomenons (pre-strike and re-strike?) cause different stresses when opening or closing. The energy following a strike/restrike tends to move back-and-forth between the internal inductance and capacitance The Chair added that re-strike/re-ignition can cause severe issues and several examples are included in the draft guide.
Page 21 of 25 e. Phil Hopkinson suggested shielded versus unshielded winding designs should be modeled and studied and further tested with the different STLI test configurations to gather more data. Mike Spurlock further commented that rather than arrester terminated, testing with capacitor terminated windings can be used to better simulate certain circuits (GSU’s for example).
9) Switchgear Liaison Update – Dave Caverly a. The C57.142 Guide is a co-sponsored document between Switchgear and Transformers and run by Transformers Committee. b. The last Switchgear liaison meeting was held with 50 people present, c. There is now an official liaison TF between the Switchgear and Transformers committees. The next IEEE Switchgear Committee Meeting will be held April 28-May 2, 2019 in Burlington, VT.
10) JWG A2/C4.52 HF TDSF Modeling principles – Xose Lopez-Fernandez/Jim McBride a. TDSF for Transformer Modeling has been added to the monitoring circuit utilized by Jim McBride for High Frequency Transient Measurements.
b. Presentation topics included transformer modeling during Transformer Impulse Transients. Measured transients were then imposed on a detailed model of the transformer. The presentation will be posted on the WG website.
11) New Business: none

3 of 13 Annex C
ii. Jeremy Van Horn requested input from the group on attachments listed under Section 4.4.1 in C57.12.31. Group added switches, PRV, lightning arrestor, brackets, grounding lug connection, gauges and animal guards. iii. Tom Dauzat asked if we want to clarify 'retain their intended functionality” under Section 4.4.1 under C57.12.31. Jim Dorsten made a motion to accept the wording as-is. Motion was seconded by Brian Klaponski. Motion was unanimously approved. iv. Dan Mulkey asked if listed attachments under Section 4.4.1 in C57.12.31 should be permanently attached to the transformer. For example, should lightning arrestors and animal guards be on this list? Group debated the meaning of attachments. Jerry Murphy reminded Dan Mulkey that guards may be permanently attached. Jim Dorsten mentioned that many utilities kit their transformers, meaning they capitalize the accessories that go with the transformer. Group decided to leave wording as suggested and will get further input when Draft 1 is circulated. v. Al Traut proposed to add welded attachments to the definition of enclosure. Taskforce 1 to include welded attachments in enclosure definition. vi.

C57.12.34 – Three Phase Pad-Mount Transformers – Ron Stahara
Ed Smith, for Stephen Shull, presented the following minutes from the working group meeting on March 25, 2019 at 3:15 p.m. with 78 in attendance.
Steve Shull called the meeting to order and introductions were made. The rosters were circulated. A “Get Well” card was circulated for Ron Stahara as he was absent due to illness. The names of those in attendance are recorded in the AM system. To establish a quorum, a members list was displayed on the screen and those who saw their names were asked to stand. From the people standing, it was determined a quorum was established. Essential Patent information was displayed and Steve Shull asked for any known essential patents to which no one responded. The agenda was presented and a motion to accept it was made by Jerry Murphy and seconded by Ed Smith. The motion was approved unanimously. Steve Shull made comment that the Fall 2018 minutes were posted on the IEEE website. A motion was made to accept them by Jerry Murphy and seconded by Igor Simonov. Steve Shull asked the members for any opposition for approving Fall 2018 minutes, to which there was no opposition. The group approved the motion unanimously. Steve started the review of the most current document at Annex A, Section A3.4. The changes shown were the consensus of the Working Group. 1. “A.3.4.1.1 Dry Well” – Gary King made a comment that he believes the loadbreak dry well canisters have been discontinued. Steve Shull modified wording in second sentence to “The canister can be provided as either loadbreak or non-loadbreak.” Steve Shull commented that he will have to look at the wording of this section and will modify accordingly and have ready for next meeting. 2. “A.3.4.1.2 Submersible” – Jerry Murphy asked the group if the submersible full range current limiting fuse is available as loadbreak. Gary King volunteered to verify Jerry’s question. Tom Callsen recommended that the last sentence to be changed to the following: “This is normally accomplished by using a type of modified Bayonet fuse assembly…”. Jim Dorsten agreed with this wording change. Rhett Chrysler made a comment that he thought the EL fuse holder had loadbreak capability. Steve commented that he believed that Rhett was correct but it could represent a safety issue unless the correct removal procedure is followed to the letter. 3. “A.3.5.1 Weak Link Fuse Assembly (Bayonet or Internal Cartridge)” – No comments on this section 4. “A.3.5.1 Mounting Options” – No comments on this section. 5. “A.3.5.2 Spill Prevention” – The last sentence states “ It should be used to make sure there is no positive pressure inside of tank…”. Gary King asked about all pressures, specifically negative pressures. Gary King commented that negative pressure could allow moisture to enter the system. Steve Shull reiterated to the group that this section specifically pertained to “Spill Prevention” only. The group was in agreement with the following change in wording “Each bayonet fuse assembly shallshould be equipped with a means…”. 6. “A.3.5.3 Fuse Link Options” – No comments on wording in this section. But a comment was made by Jeff Schneider that oil contamination will occur when many of these fuse option. Steve Shull stated that that was very good point and so he asked
5 of 13 Annex C
Jeff to generate some wording pertaining to “Oil Contamination and Gassing” that can be used at the end of each specific fuse section(s) where this issue could present itself. 7. “A.3.5.3.1 Current Sensing Fuse” – No comments on this section. 8. “A.3.5.3.2 Dual Sensing Fuse” Thomas Callsen asked the question on what temperature that the dual sensing link would melt at. Steve Shull answered Thomas Callsen that it depends on the fuse manufacturer. 9. “A.3.6 Isolation Link” - No comments on this section. 10. “A.3.7 Weak Link Fuse in Series with Partial Range Under Insulating Fluid Current Limiting Fuse” - No comments on this section. 11. “A.4 Under Insulating Fluid Loadbreak Switches” – The group agreed with the following wording change in the last sentence of the last paragraph “To that extent, a means shallshould be provided of verifying these are sufficiently immersed.”. Dan Mulkey made a comment that the oil level must be verified before operating switches. 12. “A.4.1 Labeling” – Jerry Murphy asked the question about where to apply the ground to which he answered as the obvious answer would be on secondary side. Dan Mulkey made comment to change wording in the note from “transformer” to “device”. There was much discussion pertaining the labeling of “OPEN/CLOSED” versus “ON/OFF”. Dan Mulkey uses both “OPEN/CLOSED” and “ON/OFF” on devices utilizing switches. Steve Shull commented that the wording “ON/OFF” implies transformer operation. Weijun Li made a recommendation to delete the entire note. Gary King asked the group if there was NOT a reason keep the note in this section. There were no objections from the group. Therefore, the note will remain in the section. 13. “A.4.2 Location” – Steve Shull made the comment that the “shall” in this section is important and should remain in this section. There was discussion pertaining of switch location. Rhett Chrysler made comment that from a manufacturer perspective it is easier to put a switch on the High Voltage side versus the Low Voltage side. However, it was pointed out that the section that refers to the auxiliary cabinet needs to reviewed carefully when we get to it as this section could be in conflict. 14. “A.4.3 Switch Rotation” – The group agreed on the following wording changes: “The two-position switch rotation shallshould be clockwise to close and counterclockwise to open. The four-position switch willshould be clockwise to initiate the first operation as indicated by the labeling on the switch.”. 15. “A.4.4 Current-carrying” – Dan Mulkey suggested that this section should be revised per the following: “The minimum continuous current rating capability shall be either is typically 200 A, 300 A, or 600 A.” 16. “A.4.5 Short-time Current Rating” - No comments on this section. 17. “A.4.6 Loadbreak Four Position Switch Types” – Tom Callsen made comment to break out the two-position switches from the four-position switches. Steve Shull made comment that this section is for four-position switches only. The first 2 switch references in the chart depict an “ON/OFF” configuration, but the switches were designed as a four-position switch. Jim Antweiler made comment that he has customers that utilize (2) two-position switches and/or (3) two-position switches. His
6 of 13 Annex C
comment was that this combination of two-position switches can do the same as a V- blade and T-blade switch combined. 18. “A.4.7 De-energized under Insulating Fluid Tap Changer Switch” – Dan Mulkey explained to the group about HV voltage descriptions pertaining to transformers utilizing a Delta-Wye switch. Jim Antweiler asked the group about including all other types of switches. Jim Antweiler was asked to propose wording depicting the other types of switches. 19. Due to time restraints, “New Business” was not discussed. 20. Steve Shull adjourned the meeting at 4:30 P.M. Gerald Paiva, a longtime member, made a comment that this Annex sounds like a guide. Steve remarked that since it was an informative annex, it was built in such a way to help the unsophisticated user understand the items that could be provided for a three-phase transformer.

6. Technical topics
Dan Mulkey presented data provided by Liz Sullivan of Dominion Energy. This is the largest and most details data received so far. The 2018 data is predominately from Virginia with some from North Carolina and DC.
The Transformer breakdown was:
Single-phase Overhead 26176 Single-phase Pad-mount 25088 Three-phase Overhead 3090 Three-phase Pad-mount 6370 Total 60724
Dan Mulkey was able to analyze the data to provide breakdowns base on:
· Mixed use, residential only, commercial only · Name plate kVA size · Customers per transformer (average, maximum, mode)
The Annual load factor is:
Average Annual Load/Peak Annual Load
This was analyzed for the same parameters to provide the mode and range (at half the mode).
Summary tables:
Annual Load Factor RMS Average/ Peak Load Mode Numerical Average/ Peak Load Mode Dominion 2018 All 0.288 Dominion 2018 All 0.258 Dominion 2018 Residential only 0.28 Dominion 2018 Residential only 0.26 Dominion 2018 Commercial only 0.35 Dominion 2018 Commercial only 0.37 Dominion 2018 Mixed use/comm 0.31 Dominion 2018 Mixed use/comm 0.29 Duke Energy LF 0.3 Duke Energy LF 0.2 Toronto Hydro 2013 Residential 0.29 PG&E 2006 Residential 0.39
Peak Load kW Load/Nameplate kVA Mode Toronto Hydro Residential only 0.9 Duke Energy 0.7 Dominion overall 0.46 Dominion Residential only 0.46 Dominion Commercial only 0.00 Dominion Mixed use 0.53
Lessons learned: 1. Add details on transformers in the transformer bank – e.g. is the 45 kVA 3- phase bank a single transformer or three 15kVA single phase transformers?
8 of 13 Annex C
2. Ensure that the average load calculations sums the absolute value of the load 3. Ensure that daylight savings time change does not result in an artificial report of zero load.
Phil Hopkinson thanked the utilities who have contributed data; in particular Liz Sullivan for data set from Dominion Energy. He encouraged more utilities to provide data so that a national picture of transformer loads, highlighting geographic and regional differences, can be developed. He received indications of potential contributions from Ft Collins, Knoxville and Southern Company.
7. Future Work
Phil Hopkinson noted the work being undertaken by other IEEE groups on insulating materials and permitted temperature rise for transformers. He is considering the possibility of dual plating for transformers for A) 65º raise and B) Thermal class. He will develop this proposal and report at the next meeting

Title IEEE Standard Bar Coding for Distribution Transformers and Step-Voltage Regulators
1.1 Scope This standard sets forth bar-code label requirements for overhead, pad-mounted, and underground-type distribution transformers and step-voltage regulators. Included herein are requirements for data content, symbology, label layout, print quality, and label life expectancy. This standard assumes the existence of central transformer databases within utility companies so that bar-code labels need only carry basic transformer identification data.
1.2 Purpose The purpose of this standard is to promote standardization and uniform use of bar- code labels on distribution transformers and step-voltage regulators when specified by the user. In the longer term, it is hoped that the bar codes provided as a result of this standard will serve as an integral part of electrical utility material and information management systems.
Motion by Dan Mulkey/Jerry Murphy to change ‘underground’ to ‘subsurface’. Passed unanimously.
Motion by Ed Smith/Fred Friend to change ‘within utility companies’ to ‘by users’. Passed unanimously.
Motion Dan Mulkey/Alan Wilks to change ‘Bar’ to ‘Information’ in Title and Scope. Passed unanimously.
Motion by Lee Matthews/Jerry Murphy to remove ‘central’ and ‘transformer’ from last line of Scope. Passed unanimously.
11 of 13 Annex C
Motion Steve Shull/Jerry Murphy to remove ‘print quality’. Passed unanimously.
The final revised Title and Scope is as shown below. The Purpose is not part of the PAR application so it is not included below. Once PAR is approved, the WG will decide if the Purpose will be retained or modified in the revised document.
Title IEEE Standard Information Coding for Distribution Transformers and Step-Voltage Regulators
Scope This standard sets forth information code requirements for overhead, pad-mounted, and subsurface distribution transformers and step-voltage regulators. Included are requirements for data content, symbology, layout, and life expectancy. This standard assumes the existence of user databases so information codes need only carry basic identification data.

13 of 13 Annex D Dry Type Transformers Subcommittee March 27, 2019 Anaheim, CA USA Chair: Charles Johnson Vice-Chair: Casey Ballard Secretary: David Stankes
D.1 Introductions and Approval of Agenda and Minutes
Casey Ballard, Vice-Chair, led the meeting as Chuck Johnson did not attend this meeting. The Subcommittee met on March 27, 2019 at 1:30PM in the California Ballroom A room of the Hilton Anaheim Hotel. The meeting was convened with 46 people in attendance. 16 of the 26 members of the Dry Type Subcommittee were present, so quorum was reached. Three guests requested membership. The attendance roster will be recorded in the AMS. Participants at the meeting introduced themselves and roster was circulated. The Vice -Chair reviewed the proposed Agenda. A motion to approve the agenda was made by Rhea Montpool and seconded by Mike Sharp. The agenda was approved unanimously. The Vice-Chair noted that the unapproved minutes from spring 2018 SC meeting had been posted on the SC Transformer Committee website. A motion to approve the minutes was made by Ken Klein and seconded by Jim Antweiler. The minutes were approved unanimously.
D.2 Chairs Remarks Vice-Chair reviewed required information to be included in all WG and TF minutes. These include: • The name of the activity • The date and time of the meeting • The number of members and guests in attendance. Full attendance should be recorded in the AMS system • The presence or absence of a quorum • Any essential patent issues raised during the meeting. • A summary of discussion. Intricate detail not required. Use a separate document to explain decisions that are made. • A record of the decisions made in the meeting • If there will be another meeting. If so, state the time and place. • Submit WG minutes as soon as possible, but no more than 15 days after the meeting Spring 19 due by 4/12/19.
Casey challenged TF and WG leaders to submit minutes from meetings in a timely manner, ideally before the sub committee meeting on Wednesday. Vice-Chair reminded the WG Chairs that they need to review their roster and move anyone who is not attending or participating from a Member to a Guest. Members who may be moved to Guest status or removed as Member include anyone who has missed three consecutive meetings and anyone who has communicated that they will no longer be participating/attending. Casey noted that among the DTSC membership we have two new main committee members: Ken Klein and Mike Sharp.
Page 1 of 16 Annex D Vice-Chair noted that the new copyright policy that was reviewed during the Standards Development Review Luncheon has raised many questions that need to be resolved or answered. IEEE is planning to host (five) webex training sessions in the coming weeks to address questions from members. Casey recommended attending one of these sessions and to be prepared to discuss specific examples of how the new copyright policy may impact your ability to work on standards.
D.3 Working Group/Task Force Reports The next order of business was the presentation of the reports of the various working groups and task forces. See the following sections for the individual reports:
D.3.1 Revision of IEEE PC57.12.01 - Dry Type General Requirements Chair Casey Ballard The working group met in the El Capitan Room of the Hilton Anaheim Hotel. The meeting was called to order at 1:45 PM by Chairman Casey Ballard. Chairman made opening comments. WG Roster was distributed and signed. Participants introduced themselves.
The meeting was convened with 45 participants, 19 of them are members. Quorum was reached (24 current members). 6 guests requested membership. The attendance will be reported in the AMS.
The Agenda was approved unanimously being no negative votes (after moved by J. John and seconded by D. Walker).
The Minutes of Fall 2018 Jacksonville meeting was approved unanimously (moved by T.-F. Mai and seconded by R. Wicks).
The chair made a call for known patents and took some time going over the IEEE guidelines on the patent disclosure. No patent related issues were claimed.
Old Business · Chair used the attached presentation to facilitate the discussion.
IEEE C57-12-01 Spring 19.pptx
· Chair informed that the following revision from Fall 2018 was incorporated into Draft 6 and circulated to the membership (along with some edits in support to WG decision going to ballot) o Updated impedance rating definition in Section 5.8. · Short Circuit Thermal calculation in Section 7.10 – an additional alternative method is under consideration by IEC 60076-5. D. Walker presented the changes that are considered by IEC in this regard and example of their implementation. He concluded that there is no difference in short circuit temperature calculations between the currently published equation and proposed IEC formulas for temperature rises up to 1000°C. Both match well with the existing IEEE method. David suggested to use the existing formula in this revision of C57.12.01 and consider the new formula in a future revision. R. Marek presented the draft of the Annex A (informative) to IEC document that describes the background of the new calculation. Rick proposed to include IEC formula in a current IEEE revision because, in any case, the new formula is more correct mathematically and it’s even easier to use. In support of this, motion was made by M. Iman and
Page 2 of 16 Annex D seconded by V. Tendulkar. The motion passed by 17 affirmative votes. The new formula will be included in the Draft 7 of the revision as an alternative method to the existing IEEE calculations.
New Business · D. Walker suggested to improve definitions of routine, design and other tests in Section 8.3. David made a motion to include the proposed language to make it consistent with IEEE C12.00 and follow the test sequence defined in IEEE C57.12.91 providing additional explanation for clarity. J. Antweiler seconded the motion. In the discussion, P. Hopkinson asked to check what definitions are in IEEE C57.80 because such definition shall be applicable for all IEEE standards. The language was somehow close, but the group favored (because IEEE C57.80 wasn’t as widely known and used compared to IEE C57.12.01) and voted on the initial motion; motion passes by 19 affirmative votes. The respective language will be included in the Draft 7. In aftermath of the vote, P. Hopkinson moved the concern of the repeatability of the statements on the tests, but his motion didn’t receive a second and was abandoned.
· J. Tedesco questioned the logic of the description of the impedance tolerances for duplicate transformers provided in section 9.2 under a), b) and c). In the discussion, D. Patel mentioned the practice where tighter tolerances (± 5%) are required when a series of identical transformers are produced in the same time in other industry standards. P. Hopkinson asked about whether we can find a consensus on the acceptable tolerance for paralleling transformers. Such consensus didnt exist. After additional discussion, D. Patel made a motion to reduce the text of section 9.2 to the following statement: “The impedance of a two-winding transformer shall have a tolerance of ±7.5% of the specified value. The impedances of transformers having three or more windings, or having zigzag windings, as well as autotranformers shall have a tolerance of ±10%”. The motion was seconded by T-F. Mai. Motion passed with 17 affirmative votes and 2 abstentions.
· In the following discussion, W. Li expressed the end user’s opinion that note on transformers parallel operation shall warn the users on parameters of concern for this operation. D. Walker moved the motion to revise section 4.2.6.r as follows: “Parallel operation. It should be noted that while parallel operation is not unusual, it is desirable that users advise manufacturers if paralleling with other transformers is planned and identify the ratings of the transformers involved. Users should consider the matching of unit voltages and impedances in specifying transformers for parallel operation for appropriate load sharing”. The motion was seconded by J. Tedesco. Motion passed with 18 affirmative votes.
· Chair final remarks: - PAR expires 12/31/2020. - No other new topics to be included in the final WG Draft 7. - WG will go for a ballot to submit to Dry Type SC for approval to proceed to SA ballot in Fall 2019 (this also aligns with the schedule of IEEE C57.12.91) - Next Fall 2019 meeting: Columbus, Ohio, USA, October 27-31, 2019.
With no further business, the meeting was adjourned at 3 PM. Chairman: Casey Ballard Secretary: Sasha Levin
D.3.2 Revision of IEEE PC57.12.60 - Dry Type Thermal Aging Chair Roger Wicks
Page 3 of 16 Annex D The WG met on March 26, 2019 at 1:45PM in El Capitan room of the Hilton Anaheim Hotel. The meeting was called to order at 1:45 PM by Chairman Roger Wicks. Introductions were made and attendance sheet was circulated.
The meeting was convened with 32 people in attendance. 14 of the 23 active members of this working were present. Quorum was reached. Two requests for membership were accepted based on attendance and involvement with the survey ballot. The attendance will be reported in the AMS.
The Chairman reviewed the proposed Agenda, noting the addition of New Business topic that was not in the original agenda that was sent out prior to the meeting. Motion to approve the modified agenda was made by Tim-Felix Mai and seconded by Vijay Tendulkar. The agenda was approved unanimously.
Motion to approve the minutes from the Jacksonville Fall 2018 meeting was made by Casey Ballard and seconded by Joe Tedesco. The minutes from the fall 2018 WG meeting were approved unanimously.
The chairman presented slides pertaining to essential patent claims (no issues were noted) and meeting guidelines.
Working Group Survey Results The Chair reviewed results of the draft survey that was sent out to WG members and guests. • Good input received from both working group members and guests. • 187 comments received, most of which were editorial in nature. All the comments were reviewed, and with only a few exceptions were included into the revision. • Excluded comments typically were in conflict with other parts of the document and/or did not provide an alternative. • Major areas revised will be discussed along with one significant item needed prior to completing this work.
Key Items Changed during Revision based on Survey The Chair identified three key items that were changed in the draft document based on comments received during the survey. They included: • Clarification of terminology – improved description of test objects for consistency through document. • Tying the test conditions to those called out in IEEE C57.12.01 and IEEE C57.12.91 • Significant changes to the Clause 9 which deals with the modification of an approved system.
The chair noted that much of the discussion planned for this WG meeting centered around changes in Clause 9.
Clause 9 review: • Chair noted that Casey Ballard had identified (unmaintained) IEEE C57.12.55 as a document containing a procedure to deal with changes to an insulation system such as we have in IEEE C57.12.60. This procedure has been added the to the Annex of the 12.60 draft as Annex G, and sections of this document were used to address items from our draft. • Chair noted a proposal to utilize an Enhanced Sealed Tube (EST) test. This test was described as more severe than current Sealed Tube Chemical Compatibility Test but less Page 4 of 16 Annex D severe than earlier draft proposal for a three point or one point (for certain conditions) test. The test conditions for the EST are based upon aging condition table found in current draft of 12.60. Details of the testing were discussed.
Solomon Chiang asked if current CCT could still be used for certain conditions, such as approval of chemically equivalent material substitutions and minor (non- insulating) components. Chair confirmed this would be the case.
Joe Tedesco asked who came up with the conditions for the test, and Chair responded conditions were developed with considerations from content found in the C57.12.55 document.
A question was raised regarding experience of using the EST test. Chair responded that there was data that supports its validity, but data was confidential and could not be shared.
Joe Tedesco suggested that perhaps a round robin test be conducted to validate the test. Chair responded that he was confident that test would pass with materials currently used today, but that some of the new materials may pose a problem.
Casey Ballard suggested that the 3-point test originally proposed may not work for non silicone type varnishes that have been shown to work in application due to a too high high-temperature point. Chair highlighted that EST proposal would be twice as severe as current CCT method due to 10C increase in temperature, and time period would be longer than current 336 hours. This was balanced with the fact that no other components other than the varnish and insulation material would be include in the EST test.
Casey Ballard suggested that EST test should specify that ambient air (no other gasses) should be used in the EST sealed tube. Chair noted he would add this to the new draft.
Joe Tedesco and Casey Ballard addressed concern of not specifying exact aging time, as there is a time range in the 12.60 recommended aging table. Joe Tedesco made a motion to specify the use of aging conditions found in the second line of the aging condition table found in 12.60 draft, and that aging time should be the highest value listed. Casey Ballard seconded this motion. Discussion surrounding the elimination of Class 240 in aging table due to it not aligning with IEC was made by Vijay Tendulkar. After some discussion it was decided to leave this information in the draft table and motion was approved unanimously
New Business A Note was added to Clause 3.1 in the draft document describing an alternative method to IEEE 259 for testing low-voltage windings below 600V. This method would test at a 1.2 kV voltage class level where voltage is scaled down using the method described in Clause 9.4.
Next steps Chair agreed to reorder the document for improved flow by the end of April. The Chair will then send out the document to Working Group members for an up or down vote to decide on if to move the document forward.
A Task Force for comment resolution was formed, including: · Dhiru Patel Page 5 of 16 Annex D · Tim-Felix Mai · Joe Tedesco · Dave Stankes · Casey Ballard · Roger Wicks
The WG agreed to meet again at the Fall 2019 IEEE Transformer meeting.
Meeting was adjourned at 2:55PM.
Notes prepared by Dave Stankes.
Chair: Roger Wicks Co-Chair: Dave Stankes

The minutes of the October 2018 meeting in Jacksonville were approved unanimously. Motion: Iman, Mike - Second: Tedesco, Joe
The patent call was given. No one replied with any patent issues.
Old Business - The chair presented the changes from Last Meeting. o Sound Level Revision -> Updated to match C57.12.90 with changes suggested by R. Girgis. o 50/60 Hz Results Conversion § In Fall 2018 there was concern that the conversion of noload losses might be different for dry than liquid. C57.12.90 lists the following conversion factors from 50Hz to 60Hz BT£1.4 = 1.32
BTB>1.4 = 1.32 - 0.05 ´( - 1.4) § Several members offered to provide test data. So far, none has been provided.
Page 6 of 16 Annex D § A comparison of core steel manufacturer data for a number of different core materials was shown § Discussion. · The group think that an upper limit would be good. The chair suggests 1.9T · Patel, Dhiru suggest that the factor will only be used if no other conversion data is available § Tendulkar, Vijay will send data to Chair § Motion to include 50/60 Hz Results Conversion as a normative annex into the standard Motion: Tedesco, Joe - Second: Iman, Mike (10 in favor) motion passed § Motion that the factor will only be used if no other conversion data is available Motion: Patel, Dhiru- Second: Ballard, Casey (13 in favor), motion passed
New Business: - Discussion about the scope, why are rectifier transformer excluded. This is covered in C57.10.18. - Comparison of eq 23 if it matches with IEC60076-11. IEC only addresses AN and AF cooling no sealed units. AN is the same as in IEC. AF is different (0.9 IEC vs. 1.0 in IEEE) - Discussion about eq 26, if the exponent should be changed from a fixed number to n to cover different cooling types - Motion Patel, Dhiru Second: Roger Wicks to change the exponent of eq 26 to cover different cooling types (7 in favor, 1 against 5 abstain)
Final remarks from the chairman: - PAR expires 12/31/2020 - GOAL- Complete discussion and changes by Fall 2019 meeting and have WG vote to go to ballot. Use late 2019 and 2020 for ballot process. - Goal- stay synchronized with C57.12.01 revision cycle. - Freeze changes after Spring 2019 meeting. - WG vote on draft in Fall 2019 meeting - Create Comment Resolution Group in Fall 2019. - Submit draft to MEC to start ballot process.
With no further business, the meeting was adjourned, without objection, at 5:30 PM.
The Working Group will meet again at the Fall 2019 meeting in Columbus, OH, October 27-31.
Chairman: David Walker
Vice Chairman: Tim-Felix Mai (acting as Secretary)
D.3.5 IEEE PC57.16 – Dry Type Reactors Chair Art Del Rio The working group for the revision of C57.16 met in the El Capitan room of the Hilton Anaheim Hotel on Monday March 25, 2019, at 9:30 AM. 1. Introductions and Call for Patents § The meeting was called to order at 9:30 AM by the WG Chair Art Del Rio. § The meeting was opened with the introduction of participants. § The WG Chair Art Del Rio did a call for potentially essential patents. None was reported.
2. Circulation of Rosters § The attendance rosters were circulated.
Page 7 of 16 Annex D 3. Verification of Quorum § There was a total of 22 participants: 9 Members and 13 Guests out of which 4 guest requested membership; 3 were granted based on attendance. § 9 of the current 12 WG Members were present and quorum to carry out business was met. § The meeting agenda, which was circulated by email among members and guests on March 16, 2019 by email, was presented to the participants. § There were no objections or comments and the agenda was approved unanimously.
4. Approval of the minutes of the October 15, 2018, meeting in Jacksonville, Florida. § The minutes from the F18 meeting in Jacksonville, which were circulated on March 16, 2019 by email, were presented to the participants. § There were no objections or comments and the minutes were approved unanimously.
5. Continue to discuss and review § Comments, by all, should be sent to the chairman Art del Rio.
5.a Main body of the standard sections 3 through 12. All members. § Pierre Riffon proposed to change the factor 2.55, for calculation of peak short circuit current, to 2.7. The reason is that X/R for a reactor is much higher than for AC networks and it is the reactor that provides the dominating inductance. The value 2.7 shall be used (as 2.55 today) if another value is not specified by the purchaser. Pierre has provided explanations that will be incorporated. Affected clauses are 5.63 and 10.2.2. Also clause 11.6 must be rephrased. It does now say “A system fault is typically composed of a full offset peak current …”. The term “full offset” can be interpreted as the maximum theoretical factor of 2.82 and should be replaced by the selected factor K from clause 10.2.2. § The reference to IEC 60076-10 should be changed to a reference to an IEEE standard. IEC 60076-10 should also be removed from normative references. If it is referred to from informative parts of the standard then it should be added to the Bibliography instead. § The normative references should only be references that are referred to from the main text. References that are referred to as e.g. “more information can be found in …” should be listed in the Bibliography.
5.b Scope § The scope should also cover converter reactors for SVC applications. Those reactors are stressed in a similar way as filter reactors. § Should pre-insertion inductors be added? They are used to limit the current stresses of circuit switches they do not have continuous stresses, except for dielectric stresses (if located on high potential). They could be added to a new Annex or to the existing Annex B (with explanation of differences). Standards for circuit switches might have something regarding this application. This question is parked for now.
5.c Update on proposed on 2-level, 3-level, multi-level converter reactors. Ulf Radbrandt
Page 8 of 16 Annex D § Annex G does now contain information about converter reactors, for multi-level VSC converters, that are located in series with the valve modules. Those reactors will be stressed with both AC and DC current and they will be covered by IEEE 1277 and not by this standard. Those reactors should be removed from this standard. Instead we should add converter reactors, for multi-level VSC converters, that are located in series with the transformers. The figures with voltage across and current through the multi-level converter reactors should be updated with smaller voltage steps to show a more expected wave shape. Extra figures, zoomed in e.g. at zero crossing should be added to show the principle wave shape (with small steps in voltage and corresponding result in current). Figure G.2 should be updated accordingly. Ulf Radbrandt will provide a proposal of updated Annex G.
5.d Annex B - Dry-type air-core shunt capacitor reactors. Update, Dave Caverly § No new updates. § This Annex should be in line with IEEE C37.012 “Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers Above 1000 V”. Perhaps we should have a joint TF with the SWG committee. Dave Caverly might go to the SWG committee meeting in April and can then discuss this with them.
5.e Annex A - Filter reactors update, Klaus Pointner § No new updates.
5.f Annex C – Discharge CLR for series capacitor banks, update, Mike Sharp § No new updates.
5.g Annex F - System considerations, TRV section update. Monty Goulkhah § We should add a note for Figure F.1 to explain that the source can be at any of the sides.
5.h Annex D – Reactors supplied in enclosures § The enclosures can either be for personal protection or for sound shielding. § We should explain that the enclosure should normally not be used for mechanical support of e.g. connecting cables or bus-bars. If the enclosure is used as sound shield then the vibrations from connected bus-bars might give extra noise via the sound shield. If the enclosure would be used for mechanical support anyway, then the load must be given by the purchaser.
6. New Business § There was no new business.
7. Adjournment § The meeting was adjourned at 10:43 AM.
Respectfully submitted, Chairman: Art Del Rio ([email protected]) Secretary: Ulf Radbrandt ([email protected])

D.3.7 IEEE PC57.12.52 – Task Force for Sealed Dry-Type Chair Joe Tedesco The Task Force met in El Capitan Meeting Room. The meeting was called to order at 11:02 AM by Chairman Joseph Tedesco.
Chairman made opening comments. Page 11 of 16 Annex D Introductions were made by all participants. There were 16 people present. Since this is the first meeting of the TF, all attendees will be added to the TF as members.
The agenda was approved unanimously. Motion: Dhiru Patel, Second: Casey Ballard
The patent call was given. No one replied with any patent issues.
Title of existing Standard was shown. Chair proposed simplifying the title (and scope) in a manner similar to C57.12.51by removing references to specific kVA and voltage ranges.
Casey Ballard noted that Dry Subcommittee is tending to move toward more simplified titles of standards. C57.12.01, C57.12.91, C57.12.50, C57.12.51 all simplified their titles. Dhiru Patel suggested simplifying title to first line on the existing title only.
Vijay Tendulkar moved to change title to “IEEE Standard for Sealed Dry-Type Power Transformers. Hemchandra Shertukde seconded. In discussion, Casey Ballard suggested adding “and Distribution” after “Power” in the title. Suggestion that title be such that the standard distinguished itself from any other standards. After discussion there was consensus that the existing proposal satisfies this concern.
Vote was unanimous except for one abstention. Title will be “IEEE Standard for General Requirements for Sealed Dry-Type Distribution and Power Transformers”
Chair led discussion on proposed Scope of PAR and displayed current scope. Casey Ballard suggested limiting lower voltage range to 1.2kV class. Upper to 34.5kV class. Suggestion on limiting gasses to Dry Air and Nitrogen. Jerry Murphy suggested making scope similar to C57.12.01. Casey Ballard suggested limiting System voltage to 36kV with one voltage 601V or higher. Much discussion on wording. After much discussion by the group it was agreed that limiting the voltage range to different of that in that of C57.12.01 was not required. Discussion proceeded down path of duplicating C57.12.01 scope except deleting ventilated and non-ventilated types from the scope statement. Discussion of including single phase or not, more than two windings or not. Chair displayed proposed scope of C57.12.52. Discussion of what additional exclusions are needed in C57.12.52 compared to C57.12.01. David Walker suggested wording for the exclusions to be the same as C57.12.01 plus two additions. The question was raised by Casey Ballard about whether the scope of one document could reference the scope of another document. Chair is going to ask Malia about that issue.
Because time was running out, the Chair agreed to bring proposed Title and Scope to next meeting in Fall 2019. Casey Ballard agreed to provide copy of existing C57.12.52 standard to TF. Casey Ballard to look for IEC Standard allowing SF6 as a fill gas in sealed transformers.
After a motion by Hemchandra Shertukde with a second by Vijay Tendulkar the meeting was adjourned at 12:17pm.
The Task Force will meet again at the Fall 2019 meeting in Columbus, OH.
Chairman: Joseph Tedesco
Secretary: David Walker
At the SC meeting there was a question raised as to why certain gasses were excluded from the document. Casey Ballard explained that evidence from e-mails (Charles Johnson and Sheldon Kennedy) during last revision indicated that the WG was pooled to determine if experts on other gasses were available. None were available so no information on these other gasses was included.
Following the report to the SC, Joe Tedesco requested (and was granted) permission by the SC to extend the Task Force to complete its work.
D.3.8 IEEE 256 – Low Voltage Thermal Aging Chair David Stankes
Chair: Dave Stankes
Page 12 of 16 Annex D Vice-Chair: Joseph Tedesco
This was the first meeting of the task force. There were 6 people present in person and 1 person present via phone. The meeting was held in the Balboa B meeting room and was called to order at 9:30 AM.
The agenda was approved. As this was the first meeting, there was no old business.
New Business: · Dave Stankes discussed the background that led to the development of this task force, namely that in Spring 2018, a vote had been taken in the Dry-type Subcommittee to allow IEEE 259 to be administratively withdrawn when it expired and not work on it, but in Fall 2018, it was voted that a PAR should be written to revise the standard. Joseph Tedesco pointed out that he had made the motion to revive IEEE 259 because IEEE C57.12.60 referenced it. Casey Ballard then described the situation where IEEE 259 would be used to test LV coils. · Ken McKinney was asked what UL did for testing LV coils and he answered that UL has allowed LV coils to be tested using UL 1446 and not IEEE 259. · Dave Stankes asked whether maintenance of the standard could be done in off-schedule meetings (i.e., not just at the Spring and Fall meetings). Roger did this for IEEE C57.12.58. The meetings must be publicized, and we should ask whether other members of the Subcommittee would want to participate. They may not, but we should ask. Joe Tedesco asked whether Ed van Vooren would be able to participate, given the pending IEEE rules on copyright, because his expert opinions would be valuable, even though he is not a member. Casey Ballard planned to check on this. · Dave Stankes stated that the first matter to address was why we want to bring back a standard that no one uses. Ed echoed that sentiment. Joe stated that we should not reference an expired/withdrawn standard in an active standard if we had no intention to maintain the standard that was being referenced. Ed then listed a number of standards where IEEE had done just that. Casey Ballard reminded everyone that the mandate from the Subcommittee was to write a PAR for IEEE 259. · Roger Wicks discussed aging tests, particularly aging tests for LV coils, were not being used as they were originally intended. Furthermore, he stated that the tests described in IEC 61857-1 were different from the tests described in IEEE 259, which is why IEEE 259 was called for in the latest revision of IEEE C57.12.60 and not IEC 61857-1. There was then much discussion of the actual testing. A range of issues were discussed, including physical matters underlying the performance of the test, whether testing was being performed in an unrealistic regime (e.g., there is breakdown on the surface when you wouldn’t operate your transformer in that state) internal and external phenomena, internal versus external breakdown, and whether these matters were related to processing or design. · Joseph Tedesco pointed out that IEEE 259 is an international standard, not just a UL standard. The only reason a company would go to UL is if they were seeking certification. Not everyone is doing this, so we need to allow for anyone to use IEEE 259 Page 13 of 16 Annex D if it is appropriate for their situation. Casey Ballard then pointed out that UL 1562 (for MV transformers) ultimately references IEEE 259 through other standards. Ed then stated that IEEE C57.12.60 could reference IEEE 259, even if it had been withdrawn, reminding everyone that it had been done before. If there was no interest in working on the standard, then put a date in the text of IEEE C57.12.60 (i.e., IEEE 259: 1999) and be done with it. He was adamant that we shouldn’t work on the standard unless the plan was to improve it. Dave Stankes then asked whether we should spend the time fixing a standard if no one will use it. · Tim-Felix Mai described how his company would handle certifying insulation systems. If they had a MV coil and a LV coil, they would test both using C57.12.60. Casey Ballard was unable to think of a technical reason why tests performed on a 1.2 kV class coil would not work for a 600 V class coil. Ed van Vooren pointed out that the existing published version of IEEE C57.12.60 (published in 2009) did not list voltage in either the title of scope. Roger Wicks and Casey Ballard stated that the new revision did include voltage in the scope, but the scope was copied straight from IEEE C57.12.01. · Casey Ballard and Roger Wicks discussed options for C57.12.60. o Delay C57.12.60 by revising the PAR to include testing in the IEEE 259 scope, thus negating the reason for including IEEE 259. o IEEE 259 could be left in with a date on it, thus negating the reason to revise IEEE 259, since only the dated version would be referenced. o IEEE 259 could be left in without a date, which would be useful only if we planned to revise IEEE 259. Ultimately, this option was selected. · Joseph Tedesco asked if changing the guidelines for what testing was called for would invalidate existing insulation systems. Casey Ballard and Ed van Vooren both stated that it would not. · Casey Ballard asked who would support a PAR and work in revising the standard. The following people agreed to work on it: o Dave Stankes o Joseph Tedesco o Casey Ballard o Roger Wicks o Tim Felix-Mai o Ken McKinney (Ken also volunteered his absent colleague, Mark Raymond) · Dave Stankes planned to write a PAR. IEEE 259 would be revised, improving it and modernizing it. Casey Ballard suggested that it would be appropriate to remain a task force until at least the Fall 2019 meeting and to develop the draft further before submitting the PAR, which would speed up the overall revision process.
The date of the next meeting was not set. The current meeting was adjourned at 10:48 AM.
Following the report to the SC, Dave Stankes requested (and was granted) permission by the SC to extend the Task Force in order to complete its work.
Page 14 of 16 Annex D D.4 Old Business
D.4.1 Status of Standards o The Vice Chair noted that the list of active standards along with noted board submission deadlines was available online for review. o “Red” standards that were described as either expiring or close to expiring before SASB Expiration date included C57.12.60, C57.124, and C57.12.51. IEEE 259 and IEEE C57.16 were described as “yellow”. Chair noted that the Standards Chair will be prominently highlighting the standards that are behind schedule in his future reports to SC. The IEEE Guide for Hottest-Spot Temp in Dry-Type Transformers has no active PA and SASB Expiration date of 12/31/23. Chair will approach Paulette Payne Powell who handled previous revision and ask if she would volunteer to lead this revision again. o Vice-Chair noted that ANSI C57.12.55’s copyright is owned by IEEE, but has not historically been part of the revision process as it was not published by IEEE. Should the SC determine to revise it, then it would be published by IEEE and subject to the 10 year revision process.
D.4.1 Pole mounted transformers with coils and core exposed, new work item proposal o At the last SC meeting Tim-Felix Mai made proposal that SC create a standard for pole mounted dry-type transformers that have coils and core exposed to the elements (no enclosure). Casey Ballard requested that Tim-Felix send a formal proposal and that Casey would then bring this to the main committee to determine where this work should fall. Casey reported that he brought the request to AdCom, and it was decided that this type of standard and information does not belong in the Distribution SC and , if approved, would belong in the Dry-type SC.
Tim-Felix Mai made the following motion:
I propose that the dry type SC submit a PAR for a new ‘Standard for Overhead Non Enclosed Dry Type Distribution Transformers, 500 kVA and Smaller, High-Voltage 34500 Volts and Below; Low-Voltage, 7970/13800 Y Volts and Below’
Motion was seconded by Joe Tedesco
Discussion: Steve Shull among others requested information regarding the type and application of the transformer in question, as it was suspected to be of a niche design. Tim thought that these types of transformers will be of a single phase design, although Casey Ballard stated that three phase were also manufactured. Casey explained that they were more prevalent in developing countries in order to discourage the stealing of oil (replacing oil filled designs) as well as being used in more environmentally conscious areas that impose penalties on “leakers”. Joe Tedesco also foresees increased market in areas of high population densities. David Walker asked Tim the proposed content of the standard, and Tim thought it would be similar to what is reported in liquid filled standard. Dhiru Patel voiced concern that there is only a small market in North America, and that it will be difficult to forecast requirements as they may be formed by only a limited amount of companies (users). Casey relinquished the podium to speak his personal opinion and suggested that the transformer type in question was of a niche design, and it may be more appropriate to include information on this type of transformer in annex of 12.01 or 12.91. Steve Shull pointed out that Casey’s recommendation was worth considering as a good start to breach this subject.
Following discussion, members of the SC voted on the motion proposed by Tim-Felix Mai with following results. In favor: 2 Opposed: 16 Abstain: 2
Page 15 of 16 Annex D Motion did not carry. Vice-Chair suggested to bring to 12.01 and 12.91, with recommendation to add information regarding this transformer to the annex during next revision.
D.5 New Business o Vice-Chair announced that Tim-Felix Mai has agreed to be the new Dry-type SC liaison to the WG for IEEE 12.80 (definitions) to ensure that new dry-type definitions are added and that there is alignment with the other sub committees. o Solomon Chiang posed the question asking if members of the SC should join a ballot pool for a for Dry-type standard even if not a member of the WG. Vice-Chair encouraged people to join, but stated you are not required to join especially if the standard deals with topic you are not well- versed in. o Detlev Gross expressed concern over new copyright requirements and felt that the requirements laid out by IEEE were effective at present. Many questions and concerns were raised over this subject, but not many answers could be offered. Vice-Chair reminded the SC to be sure to attend and participate at the upcoming training sessions regarding the new copyright requirements planned by IEEE.
D.6 Adjournment With no further business, the meeting was adjourned at 2:45 PM. Chairman: Charles Johnson Vice Chairman: Casey Ballard Secretary: David Stankes (Notes prepared by Dave Stankes)

E.5 Working Group Reports
E.5.1 WG IEEE P1277 - Dry-Type and Oil-Immersed Smoothing Reactors and Dry-Type Converter Reactors Chair: Klaus Pointner ([email protected]) Vice-Chair: - Secretary: Ulf Radbrandt (temporary)
Page 1 of 4 Annex E E.5.1.1 Introductions and Call for Patents
This WG meeting was conducted as part of the HVDC SC meeting.
The WG has different membership than the SC and different rosters. The WG rosters were distributed.
There were 14 members and 10 guests present. No new request for membership was received.
The total membership of the WG is 17. We needed at least a total of 9 members to be present in order to have a quorum. This was achieved.
The agenda for this meeting was unanimously approved.
We did not get quorum at the Fall 2018 meeting in Jacksonville, The minutes from the Spring 2018 meeting in Pittsburgh meeting were unanimously approved here.
The minutes as well as the agenda from the Fall 2018 meeting in Jacksonville meeting were unanimously approved.
E.5.1.2 Draft 6 and Input received for Draft 7.
A clean draft 6 has been distributed.
Comments have been received from Pierre Riffon, Chris Ploetner and Eric Davis.
The technical inputs are more or less done now and we should focus on review and corrections.
The chairman Klaus Pointner will send out draft 7 after this meeting together with the request to go forward to form the ballot pool via IEEE SA for balloting of the document.
Note: balloting prior the Fall 2019 meeting would allow 3 meetings for comment resolution an re- circulation. The document will become invalid by end of 2020. However, the PAR expires end of 2021 only.
E.5.1.3 AC power test
This is a very good test which can find e.g. short circuited loops of corona rings.
The voltage level for the AC power test is today defined as:
= 2.0
This gives unreasonably high test levels, which requires very high power, which is often impossible to achieve by test labs.
A more reasonable lest level is defined by the following equation:
= 1.5 ( )
The harmonic range is today 1 to 49. This is suitable for LCC reactors. It should be possible to extend the harmonic range to be suitable for VSC reactors – full range of harmonics shall be considered for VSC SMR’s. As the converter reactors do have considerable AC current, the AC power test is not applicable if the heat-run test is performed with AC current.
Page 2 of 4 Annex E E.5.1.4 Annex B - Construction of oil-immersed smoothing reactors
Eric Davis has reviewed this annex and considers that most of the information is covered by other standards, such as IEEE C57.12.10.
It was once decided to have this standard as free standing as possible and thereby limit the references to other standards. A problem with that concept is that the information might be old when other standards, with the same information, are updated.
Some parts as bushings are special for these reactors. Those parts should be kept but moved to the main text instead.
The decision was to delete the annex and move some parts, as bushings, to the main text and/or refer to the DC bushing standard which is available in the meantime.
Oil insulated smoothing reactors has for a long time been faded out from the market.
E.5.1.5 Further comments
Converter reactors for VSC are often placed indoors. It is then important that the purchaser specifies the ambient temperature, which normally is higher than the outdoor temperature. The minimum humidity should also be specified by the purchaser.
The rated DC voltage depends on the converter topology and must be specified by the purchaser.
References must be thoroughly reviewed. Pierre Riffon has sent a list of updated standards that should be updated in the next draft.
Extended polarity reversal test has been included in the same way as in the dual logo standard for converter transformers, IEC/IEEE 60076-57-129.
Clause 14.8.4 explains that short circuit test should only be conducted if the peak short circuit current is higher than ten times the DC current level. This does not work well for VSC converter reactor which normally conducts both AC current and a third of the DC current. We should add that the factor then is related to the r.m.s. value of the rated operating current for those reactors.
The sound section has been rewritten by Chris Ploetner and should be reviewed by others.
E.5.1.6 New Business - There was no new business
E.5.1.7. Adjournment
The WG meeting was adjourned and the SC chair, Mike Sharp, took over with the SC meeting.
E.6 Old Business - There was no old business
E.7 New Business - A new secretary is requested for this subcommittee. Volunteers are welcome to report interest. - Les Recksiedler will continue as vice chair. - Should we do an HVDC tutorial in a future meeting? The general opinion was that it is a good idea. The tutorial should mostly be focused on VSC but can also include some comparisons between VSC and LCC. A tutorial could be divided into following parts: Page 3 of 4 Annex E - Different types of HVDC projects - Different types of converter topologies - Special stresses on converter transformers - Special stresses on converter and smoothing reactors

There were very little or no comments up through sections 6.7.2 Power frequency withstand voltage from Draft 2 and 7.1.3 Thermal burden ratings of Draft 4 though there are still outstanding final edits to be done.
New business began with section 7.2.1.1 Allowable variation in ratio correction factor... and Table 11. A concurrent Task Force is studying burden recommendations and will include CCVTs in their recommendations. The review continued steadily but with some noted items: -Table 12 Accuracy limit for frequency variation phase angle deviation is considered too large and suggested values and reasoning is needed -section 7 definitions do not match Section 3 definitions and will need to be aligned -usage of IEC will need IEC permissions
The Draft 5 review was completed. Zoltan has considered proposing interim meetings. Otherwise the next meeting will be at the Transformers Committee Meeting in Columbus, Fall 2019. The meeting was adjourned at 11:59.

Unrestricted Page 6 of 7 Annex F
F.7 Old Business
Ross McTaggart indicated that a PAR was approved for a corrigendum needed for C57.13. Three areas are known to need correction. First in section 11.3.1.7 the text calls for comparison of the first full wave and the last full wave. Other standards reference comparison of the first reduced full wave to the final full wave. Second a typographical error is present in section 4.1.1 with the use of the words usual and unusual. Finally it was indicated that the definition of RCF has a discrepancy versus text provided in the metering handbook. Ross McTaggart also indicated that the PAR was approved for further development of the SSVT standard as a dual logo document with IEC.
F.8 New Business
Ross McTaggart presented information from a laboratory in Paraguay concerning the performance of current transformers under varying ambient temperatures. Vladimir Khalin indicated that he had seen similar changes in current transformers over his career. It was Vladimir’s experience that most of the difference observed was due to core padding used placing stress upon the core at extremely cold temperatures not changes due to the resistance, etc. A leadership change was announced. Ross McTaggart will be stepping down from the Chair position effective October 1st. Thomas Sizemore will assume the Chair position at that time. Nigel McDonald will take over the Secretary role. At this time the Vice-Chair position is vacant but may be filled in the future.
F.9 ITSC Adjournment The meeting concluded after a motion to adjourn by Vladimir Khalin and seconding of this motion by David Wallace. The next meeting is to be held in Columbus, OH, on Oct 30, 2019.

b. At the Fall 2018 meeting, a balloter challenged the rejection of a comment and filed an appealed to the Insulation Fluids Subcommittee (IFSC) Chair. An Appeal Review Group was formed and chaired by Jim Graham. The Appeal Review Group determined the denial was in accordance to protocol, but allowed his comments to be reviewed by the members of the C57.104 via an electronic ballot managed by the IFSC. The election results were 90% of voters were in agreement with the Comment Resolution Group’s decision.
c. The PAR was modified to reflect changes to the scope and purpose and was approved February 8, 2019.
d. The first recirculation after the initial ballot had a 93.5% return rate and an 95% affirmation rate. 19 comments were received and the Comment Resolution Group (CRG) reviewed all of the comments. The CRG results were submitted for an electronic acceptance vote on February 22, 2019. The resolutions passed with a 98% approval rate and were incorporated into Draft 6.2.
e. Draft 6.2 was released March 11, 2019 to the ballot group and had a 94.6% return rate and an 98.8% affirmation rate. Nine comments were received and resolved during the meeting, however, the comments did not address draft modifications or unresolved negatives and were considered out of scope. Seven of the nine comments were deemed editorial changes and will be forwarded to the RevCom editor for consideration.
f. This was the last meeting of C57.104 and the draft will be forwarded to RevCom for approval.

TF3 has started drafting language for the mixing of mineral oil with both natural and synthetic esters.
See Appendix II for the S19 Minutes (unapproved) of C57.166 WG Meeting as submitted.
G.3 Old Business No Old Business to review.
G.4 New Business
a. It was discussed whether or not retrofilling should become its own guide, A motion was made by Tom Prevost that retrofilling is a subject that should be covered under C57.166, Task Force 3 led by Alan Sbravati. Depending on how the content evolves, it may be up for review at a later time to remove the content and create a separate guide. The motion was seconded by Alan Sbravati. During the discussion, Paul Bowman shared that retrofilling is discussed in Annex B of C57.147. The motion carried with a vote of 27 in favor, 2 abstentions and 0 opposed.
b. Juan Castellanos, who serves as the Chairman of the IEC Mexican chapter, raised the issue of mixing new and re-refined mineral oil, and stated that IEC6092 wants TC10 to remove the requirement of excluding re-refined oil from the IEC standard. Tom Prevost pointed out the issue is with ASTM (D3487), not IEEE. The matter was considered out of scope for the IFSC.
c. As a follow up to the motion to renew the C57.146 PAR, Deanna Woods volunteered to serve as Chair. In addition, Jon Karas volunteered to serve as Vice Chair and Toby Johnson volunteered to serve as Secretary.

5 Ballot and CRG before F2018
· Ballot pool call issued in December 2017 and Ballot pool consisted of 184 participants, including 32 members of the WG · At the spring 2018 meeting, draft 4.3 was approved unanimously and was issued to the ballot group, as draft 5.0, on April 13, 2018 for a two months ballot review and reached consensus (>75% approval) with 88% affirmative. · Comment Resolution Group completed their review of the ballot comments (409 comments) in time for the Fall 2018 meeting · Major draft changes were reviewed at the Fall 2018 meeting · WG voted acceptation of the CRG work and Draft 6.0 was distributed to the ballot group on November 26 for a one month recirculation (recirculation #1)
Activities since F2018 meeting
Challenge to Comment Resolution Group (CRG) resolutions to initial Ballot comments
A balloter of the initial ballot (C57.104 Draft 5) challenged the Comment Resolution Group’s (CRG) rejection of comments i350-i352 and requested to present additional material supporting the challenge to the working group at the fall 2018 Jacksonville, Florida working group meeting. The request was ruled out of order by the WG chair based upon the agenda sent in advance.
The balloter subsequently filed an appeal with the Insulating Fluid Subcommittee (IFSC) Chair. An appeals group was formed and tasked with reviewing the process of submission of the comments via the ballot process, the handling of these comments by the WG Chair, and whether the commenter had reasonable opportunity to support the submitted . The Appeal Review Group did not review the technical aspects of the comments. The Appeal Review Group was chaired by Jim Graham.
The Appeal Review Group found that the balloter had been given multiple opportunities to present and defend the comments, and that it agreed that the denial to allow a presentation at the fall 2018 meeting was proper and not due to personal bias. However, since it was not clear that the WG as a whole had been exposed to the technical arguments presented in the ballot comments, it was recommended that the balloter’s presentation and documents be circulated to the WG for review and comment.
6 The 85 WG members were presented with the background and materials provided by the challenger in an email poll sent out on December 13, 2018 by the IFSC Chair to all C57.104 WG members. The vote was managed by the IFSC. A total of 43 responses to the poll were received, which met the minimum quorum requirement. With the 43 respondents, 22 votes or greater were required for a majority approval. There were 36 votes in agreement with the CRG resolutions on comments i350, i351, and i352. The following is the result of the electronic vote:
Agree: 36 Reject: 3 Abstain: 4 Approval rate (%): 90% (abstentions do not count toward approval percentage, only toward quorum)
PAR Changes
In accordance with comments i-299, i-386 and i-387 resolution, a PAR change request was made on November 1, 2018:

Ballot and CRG status
Comment Resolution Group completed their review and disposition of recirculation 1 comments.
Their review and disposition was circulated to the WG for an electronic acceptance vote on February 22, 2019.
A contest of the WG electronic vote validity was received on February 27, 2019 as follows:
“I respectfully object to this working group electronic vote based on the IEEE bylaws I-300.4(4). I also request time at the upcoming working group meeting to present and discuss information to support my first recirculation negative ballot for IEEE PC57.104, “IEEE Guide for the Interpretation of Gases Generated in Oil-Immersed Transformers.” I also request to present overhead material with text, and graphs, and equations for discussion at the meeting. Thank you.”
IEEE SA confirmed to the commenter the validity of the WG electronic vote on March 1st and also specified to the commenter the channel for presenting related material: “We checked with Governance staff, according to the WG policies, the decision to have an email ballot is at the discretion of the WG chair (the applicable rule is sentence 1 of Clause 7.2 WG policies) and the paragraph in the bylaws which you asked about: ‘If a majority consent, which sets forth the
8 action, is signed, or acknowledged via e-mail by a majority of all the voting members of the board or committee, as the case may be.’”
“That statement in the IEEE Bylaws discusses verification of who voted; i.e., is there confidence in the email address of each balloter, which sets forth whatever action is in the email ballot. I hope this interpretation clarifies the bylaws for you.”
“The draft is in the hands of the balloting group and the consensus ballot is the Sponsor Ballot (Standards Association Ballot) not the WG. So if you have material that the consensus group needs to decide upon, please share it in the Ballot group as an official record of your comments. ”
The result of the WG electronic vote is as follow: 66 Returned votes (Quorum = 43) 58 Approves (98% approval rate) 1 Disapprove, with comments 7 Abstains
The review and disposition of Recirculation #1 new comments (19), with updated PC57.104 Draft 6.2, was sent for a 10 days recirculation (no. 2) on March 11, 2019 to the ballot group.
Comments received in recirculation 2
Once the proposed standard has achieved 75% approval, comments in subsequent ballots shall be based only on the changed portions of the balloted standard, portions of the balloted standard affected by the changes, or portions of the balloted standard that are the subject of unresolved comments associated with Do Not Approve votes.
If comments are not based on the above criteria, the comments may be deemed out-of-scope of the recirculation. Such comments need not be addressed in the
9 current standards balloting process and may be considered for a future revision of the standard.
R02-1. Comment (5.4, p29, line 38): “It is my understanding that the normative values in the Tables were based on manual DGA sampling. Particularly as it relates to Table 4 gassing rates, the tables will not be applicable to on-line DGA monitors which can sample multiple times per day. The DGA rates for on-line monitoring will be much higher than that proposed in Table 4 and will be more accurate.”
Proposed change (5.4, p29, line 38): “Change the sentence to : “The norms shown in Table 1, Table 2, Table 3 and Table 4 below were obtained by statistical analysis of a large database of manual DGA results.” Note: “laboratory” is used in the draft instead of “manual” and for Table 4 the title does refer to “laboratory DGA”.
Claude asked if there was a motion to pass this on to the IEEE Editor to consider this as an Editorial revision. A motion was made by Jim Thompson and seconded by Kumar Mani. The motion was successful.
R02-2 and R02-3 Comments: “Normative values for on-line monitoring will be different than that in Table 4, if the samples are taken at frequencies typically used by on-line monitors; i.e., multiple samples per day.”
R02-2. (5.4, p31, line 4) Proposed change: “Change the sentence to ‘Values in Table 1, Table 2, Table 3 and Table 4 might need to be adjusted to meet specific user requirements, such as on-line monitoring data interpretation, or for a specific transformer population’”
Claude asked if there was a motion to pass this on to the IEEE Editor to consider this as an Editorial revision. No motion was brought forward.
R02-3. 6.1.4, p39, line 8 Proposed change: “Insert at the end of line 10 ‘Use of on-line monitors simplify the gassing rate calculation and establishment of gassing rate limits. Samples taken at consistent intervals, with known repeatability and accuracy, help the transformer owner and operator to better detect changes in the gas levels and gas rates of change, and to more accurately calculate their values, compared with manual samples taken at less consistent intervals.’”
R02-3. 6.1.4, p39, line 8 Proposed change (suite): “Gassing rates for on- line monitors are not addressed in Table 4. Transformer owners and operators are strongly encouraged to perform their own study based on their own on-line monitoring data."
Claude asked if there was a motion to pass the above two proposed changes on to the IEEE Editor to consider this as an Editorial revision. No motion was brought forward.
R02-3. 6.1.4, p39, line 8 Proposed change (suite): “Change the first sentence in line 11 to ‘However, the work performed in the analysis of
10 manual DGA results indicated that obtaining ...’. Note: “laboratory” is used in the draft instead of “manual””.
Claude asked if there was a motion to pass this on to the IEEE Editor to consider this as an Editorial revision. A motion was made by Tom Prevost and seconded by Jerry Murphy. There was discussion on whether these are really editorial The motion was successful.
R02-4. Comment (Annex B, p51. line 21): “The Annex is describing a "false positive". In a similar vein, samples taken one day apart and theoretically containing the minimum amount of laboratory equipment error can give a false indication of a small or no change (a "false negative") in the gas generation or generation rate.”
Proposed change: “Add ‘Similarly, samples taken one day apart and theoretically containing the minimum amount of laboratory equipment error can give a false indication of a small or no change in the gas generation or generation rate.’ to the end of the paragraph.”
Claude asked if there was a motion to pass this on to the IEEE Editor to consider this as an Editorial revision. A motion was made by Mickel Saad and seconded by Marcos Ferreira. Discussion: Tom Prevost indicated he believes this to be technical not editorial. Jerry Murphy asked if this was written as part of the document, it was indicated that it was. He indicated that he agreed it was not editorial. The motion was called to a vote. Three were in favor of the motion, fifteen opposed, five abstained. The motion did not carry.
R02-5. Comment (Annex B.1, p53. line 11): “It is my understanding that the normative values in the Tables were based on manual DGA sampling. Particularly as it relates to Table 4 gassing rates, the tables will not be applicable to on-line DGA monitors which can sample multiple times per day. The DGA rates for on-line monitoring will be much higher than that proposed in Table 4 and will be more accurate.”
Proposed change: “Revise sentence to: ‘Table 4: 95th percentile of rates (slopes) obtained from 3 to 6 consecutive manual DGA over a period of 4 to 24 months (Rates) normalized in µl/l/year (ppm/year).’” Note: “laboratory” used instead of “manual” in the guide.
Claude asked if there was a motion to pass this on to the IEEE Editor to consider this as an Editorial revision. A motion was made by Jerry Murphy and seconded by Dave Wallach. The motion carried
R02-6. Comment (Annex B.3, p58. line 10): “Point 12 should be excluded when calculating the gassing rate for segment 2.”
Proposed change: “A second group of data indicating a stable gas level (points 8 to 14; excluding point 12) (Dashes - Dots line)”
11 Claude asked if there was a motion to pass this on to the IEEE Editor to consider this as an Editorial revision. A motion was made by Kumar Mani and seconded by Marcos Ferreira. There was discussion regarding whether the addition of this was out of order with the next statement regarding the outlier. The graph above includes the indication of point 12 as an outlier. The motion carried
R02-7. Comment (Annex B.3, p59. line 24): “The sentence refers to a ‘priority confirmation sample’ yet the sample is taken 26 days later. Additionally, the term priority sample is not defined.”
Proposed change: "Remove the word ‘priority’ but continue to refer to it as a ‘confirmation sample’ or refer to it as a surveillance sample consistent with Clause 4.3.”
Claude asked if there was a motion to pass this on to the IEEE Editor to consider this as an Editorial revision. A motion was made by Emilio Morales-Cruz and seconded by Deanna Woods. The motion carried
R02-8. Comment (Annex H.2.3, p101. line 18): “Although successfully in use for over a decade in large on-line DGA monitoring fleets, no mention of Artificial Neural Networks was made in the guide as an analysis method. The method was presented to the IEEE Transformers Committee in Montreal in 2006 and to date has successfully analyzed approximately ten million samples.”
Proposed change: “Add as B130: ‘Lamontagne, D. R. ‘An Artificial Neural Network Approach to Transformer Dissolved Gas Analysis and Problem Notification at Arizona Public Service’, EPRI Substation Equipment Diagnostics Conference XIV, San Diego, Jul. 2006’”
R02-9. Comment (Annex H.2.3, p101. line 19): “Both Annex A.3, Lines 27 - 28 and Annex B.3 Example 2 discuss or demonstrate the need for a peicewise linear approximation method for accurately calculating gassing rates. The method was first presented at the EPRI Substation Equipment Diagnostic Conference over a decade ago. This method has accurately predicted high energy arcing event gassing rates and severity with sufficient warning to successfully de-energize multiple transformers and preventing catastrophic failures.”
Proposed change: “Add as B131: ‘Lamontagne, D. R., ‘Utilizing Harmonic Regression and Piecewise Linear Approximation to Analyze Power Transformer Insulating Oil Dissolved Gas Samples’, EPRI Substation Equipment Diagnostics Conference XV, Orlando, Mar. 2008’”
Claude asked if there was a motion to pass this and the previous bibliography addition on to the IEEE Editor to consider this as an Editorial revision. A motion was made by Jerry Murphy and seconded by Marcos Ferreira. A question was asked whether the comment was indicated as Technical or Editorial in the Ballot. The ballot commenter indicated that they were Editorial. The motion carried
12 Resolution: Comment R02-1 to R02-9 are not addressing changes or unresolved negative in draft 6.2 distributed for recirculation 2. Therefore they are out of scope and were rejected.
New Business:
There was a question regarding the e-ballot with negative ballots and whether these comments will be included in the minutes. The Chair indicated that the minutes will be published on the web site as unapproved since this will be the last meeting of the WG and the response to the electronic ballot from Jim Thompson would be included (see Attachment A).
Claude expressed his thanks to Don Platts and Norm Field for their work as Vice Chair and to Susan McNelly for her work as Secretary. He also expressed a special thanks to Dave Hanson for it support and comprehension in regards of the time Claude used in the preparation of this guide. Jim Graham also expressed his appreciation to Claude for the significant efforts on this document.
Finally, the WG Officers wish to thank all of the Task Force chairs, the DGA data contributors, the hosts of many multi-day meetings that occurred throughout the years of developing this Guide to the TF members, to the WG Members and to the previous Chair, Rick Ladroga.

14 C57.104 WG Minutes – Attachment A Excel line no. 3, BRG PC57.104 1st recirculation ballot responses and electronic vote comments to working group from Jim Thompson. This issue was addressed by the BRG after the original ballot. It was rejected then, and should be rejected again. 1. There are other more widely used laboratory methods, such as ASTM D3612 Method C. [Comment (JT.3/8/2019) Method has no stated precision statement for reproducibility. For repeatability it has only an “Interim Precision Statement for Repeatability for One Laboratory” reporting on twelve samples tested repeatedly. In that data, with the exception of CO2, the test method uncertainty is greater for each individual gas (repeatability interval is greater) than method B.]
2. The values in Table 4 of Draft 6 are based upon an examination of 3 to 6 samples, which is a great improvement upon the 2008 edition which only requires a comparison of 2 oil samples. This change alone is a significant step towards addressing the challenge of measurement equipment accuracy/repeatability of results, which the 2008 edition did not address. [Comment (JT.3/8/2019) The linear regression of three to six samples does not resolve the precision of the test method resulting in false rates due to the method variations for each sample test result. This is due to the fact that the table 4 rates (ppm/year) are so low that the signal to noise ratios for table 4 are under 1:2 (1/2 signal amplitude vs. 1 noise amplitude). The uncertainty inherent with the test methods, ASTM D3612 A, B and C, results in repeatability and reproducibility ppm variations that exceed the real changes that would be sought in Table 4. For example, look at just the table 4 value for variation of 50 ppm/year H2 over a period of four months. The method B repeatability standard deviation is (0.17/1.96)*(200 ppm) for a 200 ppm H2 start value. That gives 200 +17 and – 17 ppm for a 95% confidence interval for the first test. But the monthly rate sought is (50/12 ppm per month or 4.2 ppm per month).
3. The proposed change is to ""reintroduce the tables in C57.104-2008 to replace Table 4."" Only Table 4 of C57.104-2008 pertains to dissolved gas generation rate, and that table only utilizes Total Dissolved Combustible Gases (TDCG) to assess severity of gassing. This proposal does not address the comment's concern, and in fact worsens the problem. TDCG masks the possible severity of the rate of individual gases generated in the oil, and being a summation of individual measurements, the accuracy/repeatability problem would be compounded, not lessened. TDCG also has the inconvenient that all gases have the same impact on the evaluation, so for example C2H2 change is treated at the same level as CO. while in fact it should be of much more concern. [Comment (JT.3/8/2019) The 2008 document tables would be enhanced by using the tables 1 and 2 in the draft as well as guidance for sample intervals for retesting based on individual gases as an annex.]
Excel line no. 4, BRG PC57.104 1st recirculation ballot response and electronic vote comment to working group from Jim Thompson. This issue was addressed by the BRG after the original ballot. It was rejected then, and should be rejected again. This comment is of the same concern as Comment 25980100023 (r1-18) above, with the same Proposed Change, and therefore is given the same Disposition Status. . [Comment (JT.3/8/2019) Again, the uncertainty inherent with the test methods, ASTM D3612 A, B and C, results in repeatability and reproducibility ppm variations that exceed the real changes that would be sought in Table 4. Furthermore analysis of linear regression for 3 to 6 samples, using the ASTM D3612 method precision statements and table 4 values (ppm/year), shows that confidence intervals overlap 15 of 23 Annex G
for no change and 50 ppm/year change. Figure one, for H2 for example, shows that the 95 % confidence intervals for linear regression of 2 to 6 samples (1 to 5 sample intervals of one month each). This overlap demonstrates that even with linear regression the rates in table 4 cannot be distinguished from the false rates due to the method variations for each sample test result used in the linear regression.
Excel line no. 10, BRG PC57.104 1st recirculation ballot response and electronic vote comment to working group from Jim Thompson. Suggesting specific time periods for resampling was purposely omitted. The owner/operator of the transformer must decide their risk tolerance based on DGA Status and fault-type interpretation, and create their own maintenance plan accordingly. Any suggestion of a specific maintenance schedule may or may not be adequate for a given maintenance program, and may or may not expose the oil sampling personnel to safety risk when handling an unhealthy transformer. Recommending more frequent sampling as the DGA status increases is sufficiently clear and useful guidance. [Comment (JT.3/8/2019) The suggestions in the 2008 document are for resample intervals to help ascertain fault type(s) in a timely manner. The other suggestions in the 2008 document are well established suggestions to help ascertain fault types. And whether it is resampling over 4 to 6 months described in this draft (without sample interval guidance) or it is resampling days, weeks, or months (with sample interval guidance) – both carry the same risk. Again, there is serious omission in the absence of guidance for time intervals for taking follow-up samples. And while the Surveillance definition
16 of 23 Annex G
describes this protocol for testing intervals of days, weeks, and months, still there is no guidance for those sample intervals in this document.
Excel line no. 11, BRG PC57.104 1st recirculation ballot response and electronic vote comment to working group from Jim Thompson. In the balloter's supporting document to his comment (99276600003), the balloter seems to misunderstand the use of Table 3. The balloter is concerned that 2 consecutive oil samples taken 4 months or less apart will not be considered by Table 3. However, Table 3 is applied to consecutive sample regardless of the time between samples. Therefore, within that 4 month time, there could be any number of consecutive samples that are taken a very short time apart (less than 4 months and with no minimum limit). So, 2 consecutive oil samples taken 4 months or less apart are indeed covered by Table 3 as written. Table 3 does cover punctual change between consecutive samples, not rate, and as such it was never intended to identify a change that exceeds an "acceptable rate", only to identify a ponctual chage as being higher than the usual DGA fluctuations. See section B.1. [Comment (JT.3/8/2019) The heart of DGA is ΔV/Δt (rate of change in ppm dissolved gases in oil per change in time). Looking at ΔV, which is indeterminate with regard to rate of change, is not a useful metric unless one knows the associated Δt.
Excel line no. 12, BRG PC57.104 1st recirculation ballot response and electronic vote comment to working group from Jim Thompson. This topic that was previously addressed by the BRG. There seems to be multiple misunderstandings by the Balloter.
1. Yes, a subset of DGA data which contained multiple DGA results for the same transformer were used to create the multi-point values shown in Table 4. Just as subsets of DGA data were used to create the ppm values shown in Table 1 as a function of age and O2/N2 ratio. Such subsets were created starting from the entire DGA database. The 2008 edition of the guide, based on a dataset from 1972, could not create such subsets, lacking both the breadth and depth of information to do so. [Comment (JT.3/8/2019) Ok, then this subset of data does not represent the entire data. For instance looking at the box plots in the F13 working group presentation on page 41, a value of 173 ppm/year for the 95th percentile is calculated for the monthly sample intervals by using the values in the box plot to determine the standard deviation for that sample interval.] 2. The oil sample intervals considered to create Table 4 were not restricted to consecutive samples taken at least 4 months apart. The total time interval, for multiple samples, was limited to 4 months minimum. Each pair of consecutive samples may have been much less than 4 months apart. [Comment (JT.3/8/2019). Ok, but again these consecutive values and the 95th percentiles used in table 4 are a subset of the entire data set and do not represent the entire data. Again at best it represents variations for quiescent DGA rates in the subset of data.]
17 of 23 Annex G
3. The rate of change in DGA test results from factory acceptance tests are completely outside the scope of this guide, and not intended to be extrapolated up from a time period of hours to a time period of one year. Such an action would be completely contrary to good sense. [Comment (JT.3/8/2019). The fact that DGA test results from factory acceptance tests are outside of the scope does not mean they cannot be considered as a bench mark. For example if a new transformer is loaded at full load at the factory and at constant factory ambient temperature for a relatively short time does this help to predict how that same unit will fare with regard to Table 4 values when DGA tests are performed on that same unit in a customer’s substation in higher ambient temperatures and for longer time frames at full load. That is an important reason consider these values.

Chairman Prevost posted the Patent Claim. No claims were made. 19 of 23 Annex G
Chair’s Remarks: Chairman Prevost reviewed the scope and purpose of the guide. Next, the chair asked each task force to speak about their respective sections.
TF1-Types of Insulating Liquids, Jinesh Malde Jinesh shared a draft guide combining all the information from the existing standards. In addition, the task force identified the appropriate liquid tests and their significance as well as evaluate new liquids to be included as part of this guide. A discussion was raised around the inclusion of ASTM D877. The task force position is suggesting to keep as it is used typically for the maintenance. Jim Thompson raised the relevance of using the D877 for voltage regulators, tap changers and other equipment were this is the applied standard. Bob Rasor mentioned that D877 is no longer applied for transformers in the C57.106 guide.
Jinesh presented the suggestion of the TF to use the nomenclature of High Molecular Weight Hydrocarbons. Jimmy Rasco recommended using the ASTM nomenclature, which is High Fire Point Mineral Electrical Insulation Oil. Sasha mentioned the relevance of registering the history of the terminology. Claude suggested including some informative annex with additional history background. Tom suggested using the initial session of the background information. Jinesh will take it back to the task force the task of defining an abbreviation to be used.
The definitions of Unused / New / Prior to use / In Service were discussed. Jeff Valmus expressed the preference for the term “unused”. A question around how to classify a liquid in a spare transformer not energized during 25 years. Jinesh and Tom advocated this would be as a “prior to energization” condition. Jim Thompson refers to the C57.93 as a guidance for the storage and the tests to be applied to this situation.
Jinesh asked for help for completing the information about silicone liquids, as the task force was not able to get inputs. Tom asks the audience for reference of were silicone is used. John John from Virginia transformer mentioned they have not received any request for quotation for new transformers filled with silicone liquid during the last 10 years. Rainer F. from MR offered to help with the information about silicone liquid. Bob Rasor mentioned SD Myers is servicing transformers filled with silicone liquid.
TF2- In Service, Scott Reed Scott reviewed the relevant tables from the existing guides. He reported that TF2 is dependent on the format that TF1 takes on what liquid test values will be reported and also questioned whether any new liquid tests should be added to the guide. The group discussed the quantity of tests to be included for routine tests. For the natural esters tables the reference was table 4 of C57.147. Scott mentioned the absence of limits for dissipation factor, for example. Alan Sbravati explained these values are presented in the Annex B of the standard, as provisional. Tom Prevost mentioned this revision is the moment to collect more data and move the values to the main table. Regarding synthetic esters, Scott mentioned the need to work closely with the TF1, as the ASTM standard for unused synthetic esters is under development. At the moment there are no threshold limits defined in standards. Rainer Frotscher mentioned the existence of an IEC standard, which is valid for up to 35kV. Available information and limits for silicone liquid and HMWH are very limited.
TF3-Mixture of Insulating Liquids, Alan Sbravati Alan prepared a first draft for this session, including information around the issues of mixing silicone with any other of the liquids, on the impact of mixing mineral oil with natural esters and also with synthetic esters and on the mixing of natural and synthetic esters. New volunteers joined the task force, who will revise the text prepared by Alan. They are: Mike Bonn; Ed Casserly; David Sundin; Nikola Lukenda; Bob Rasor, Jon Karas and Larry Christadoulou.
TF4- Maintenance of Insulating Liquids, Rich Simonelli Rich is focused on the Reprocessing and Reclaiming of in service fluids. TF4 determine they have enough expertise on mineral oil and esters but needs more support with Less Flammable Hydrocarbon Fluids. TF4 is developing and consolidating guidance on Corrosive Sulphur and application / maintenance of Passivators. TF5 expects to have a draft guide available August.
T5- Insulating Liquids for LTC’s, Rainer Frotscher
20 of 23 Annex G
Rainer presented the application guides his company use as manufactures of tap changer and the available tables from IEC standards. Due to the variety of acceptable limits Tom mentions the need of consolidating the information.
Old Business: Chairman Prevost addressed ‘New’ Insulating Liquids and Voltage Classes.
New Business: No new business were presented.
The meeting was adjourned at 3:02 pm.

The meeting was called to order at 1:45 pm by Chair Tom Prevost.
There were 27 of 35 members present. There were 78 guests. A membership quorum was achieved.
Agenda 1) Introductions 2) Approval of Agenda 3) Approval of Spring 2018 Minutes 4) Call for Patents 5) New Document: a. Title b. Scope c. Purpose 6) Review of Documents and Task Forces 7) Task Force Reports 8) New Business 9) Adjourn
The Spring 2018 minutes were unanimously approved. The Fall 2018 agenda was unanimously approved.
Chairman Prevost posted the Patent Claim. No claims were made.
Chair’s Remarks: Chairman Prevost reviewed the scope and purpose of the guide. Next, the chair asked each task force to speak about their respective sections.
TF1-Types of Insulating Liquids, Jinesh Malde Jinesh announced his committee met October 14th and has 11 members. The task force will begin to consolidate information from the existing guides and is in the process of identifying background information for each fluid type. In addition, Jinesh will work to identify the appropriate liquid tests and their significance as well as evaluate new liquids to be included as part of this guide.
TF2- In Service, Scott Reed Scott shared that his task force has meet and will consolidate information from existing guides that discuss in- service liquids. However, the task force has questions about voltage classes and thresholds for liquids that do not have any established values, as well as consideration for new liquid tests and new liquids. It was decided that TF2 will work with TF1 as they work to establish thresholds for as supplied, as received, and after filling as well as any new liquid tests that should be included. Chair Tom announced that voltage classes will be added to the Spring 2019 agenda.
TF3-Mixture of Insulating Liquids Alan Sbravati has agreed to take over as task force chair for mixture of liquids. Alan questioned how retrofilling should be handled in this guide, It was decided to bring the question before the Insulating Liquids Sub-Committee of whether to make retrofilling it’s own guide.
TF4- Maintenance of Insulating Liquids, Rich Simonelli Rich reported that he is still looking for volunteers for his task force. Jim Thompson, Mike Lau, Jon Karas, Andrew Holden and Jimmy Rasco volunteered to assist. Rich also questioned whether re-refined oil is a maintenance classification to consider. It was decided it would not be considered as part of the task of maintenance since the oil is treated off site. It was further decided that more information is needed from ASTM to determine if this is a liquid for consideration under this guide.
22 of 23 Annex G
T5- Insulating Liquids for LTC’s, Rainer Frotscher Rainer delivered a presentation that defined the parameters and the relevance for tap changers and the specific requirements of different liquids used in tap changers. The task force also identified the suitability of liquids for different tap changer types. The task force also identified potentially new liquid tests for both new and in-service liquids that should be considered for tap changer applications as well as developing thresholds for greater than 230 kV.
Old Business: Chairman Prevost addressed ‘New’ Insulating Liquids or ‘Unused’ Insulating Liquid previously questioned.
As supplied by manufacturer: D3487 As received: C57.106 meet D3487 and Table 1. After filling: C57.106 must conform to Table 2 (230 kV or > 230 kV).
The working group will continue the discussion of new liquids at the next meeting.
New Business: Chairman Prevost stated that voltage levels within the acceptance tables will be discussed at the next meeting. Introductory material to facilitate this discussion will be distributed before the next meeting.
The meeting was adjourned at 3:00 pm.

Working Group on C57.162 Guide for the Interpretation of Moisture Related Parameters in Dry, Gas Insulated and Liquid Immersed Transformers and Reactors – Tom Prevost
The WG met on Monday at 1 pm. The Chair skipped introductions in order to save time and a quorum was established. Quorum was achieved by having 35 out of 60 members present in the meeting.
The Chair called for the approval of the Spring 2019 agenda. James Cross motioned and Scott Reed seconded the motion. The chairman called for approval of the Spring 2018 minutes. Don Doris motioned and it was seconded by Sam Sharp. The Chair then called for approval of the fall 2018 minutes. Don Doris motioned and James Cross seconded.
The Chair also provided information related to Essential Patent Claims, and none were noted.
The Chair proceeded to review the discussion from the Fall 2018 meeting. At this meeting changes to the scope of the document were agreed to. The changes were to remove the words “Dry and Gas Insulated” from the title and the scope and to focus on liquid insulation transformers. Task force 2, which covered moisture in gas insulation would be discontinued. The new scope would remove gas and dry from the scope. The statement below reflected a motion to change the scope, as flows with crossed out information being removed: “Guide for the Interpretation of Moisture Related Parameters in Dry, Gas Insulated and Liquid Immersed Transformers and Reactors”. Dave Wallace motioned for the change in scope and Jim Thompson seconded the change.
Page 3 of 17 Annex H

Working Group on Application of High-Temperature Materials IEEE P-1276 – Roger Wicks
Page 4 of 17 Annex H
The WG for P1276 did not meet as the document is in comments resolution. The ballot was successful, with an 82% response rate (above 75%) and an 87% approval rate (with an additional 5% abstention rate). Of the 306 comments received the vast majority of them are easily accepted (as editorial changes), leaving around 80 comments (many of which are similar in nature) to be resolved by the comments resolution group (CRG). Work on the editorial changes has begun, and the first meeting of the CRG was intended for the Spring 2019 meetings week, but one of the members was on vacation, so the group will do a phone conversation within the next few weeks to complete the work. The goal is to have a document ready for recirculation by the end of June. WG Chair requested and received a PAR extension to the end of 2020 to allow for time to complete the work.
Working group on C57.100 IEEE Standard Test Procedure for Thermal Evaluation of Liquid-Immersed Distribution Transformers – Roger Wicks
The Chair called the meeting to order at 9:15 a.m. and welcomed attendees. As the PAR to revise the standard was approved after the last meeting, a WG has been formed, based on requests at the last two meetings, with 42 members. After introductions, attendance was taken, and of the 42 WG members, 28 were present, achieving a quorum to conduct business.
The meeting agenda was reviewed, and a motion was made for approval by Mike Shannon, seconded by Bruce Forsyth. The agenda was approved unanimously. The minutes of the last (Fall 2018) meeting were distributed previously, and a motion was made to approve the minutes by Tom Prevost, seconded by Rick Marek. The minutes were approved unanimously. The Chair also provided information related to Essential Patent Claims, and none were noted.
The Chair then reviewed the status of the standard, noting that the PAR was approved with an expiration date of December 2022, and that the document has an expiration date of December 2021. He then also quickly reviewed the previously agreed title, scope and purpose from the PAR submission.
There were 106 total attendees at the meeting, 29 members, and 77 guests. Since this was the first meeting of the WG, guests from the meeting who requesting membership were added as members. With 17 additional guests requesting membership, the total number of members (for the next meeting) will be 59 (including the task force Chair and Secretary).
Reminder of key items identified during last fall’s meeting
The key items identified in the Fall 2018 meeting as potential updates to the standard, which were reviewed by the Chair include: · Industry Proven System Definition o Addition of PVF Enamel and Pressboard · Location of tests within document (main body vs. Annex) o Sealed Tube, Dual Temperature, Lockie Test · Clarity around sealed tube test o Pressure Relief · Ratios (volume, weight) – applicability of one test vs. other applications, etc. · Time duration to correlate to in the test o 180,000 (current) or shorter durations · End of life of materials test
Page 5 of 17 Annex H
o Correlate to IPS (at time above or shorter) o Correlate to minimum value (how to determine)
Discussion that followed included: - Question was asked if ASTM has standards or guidance about aging, and ASTM liaison Tom Prevost replied that ASTM only covers the test methods themselves, and not how to apply them to aging. - Alan Sbravati commented that 180,000 hours is transformer life, but sealed tube testing looks at material life, and Roger Wicks agreed that the challenge is how to relate materials life testing to transformer life. For example, IEC likes to use 20,000 hours, but the problem is how to extrapolate to 180,000. - Luiz Cheim echoed the challenge to correlate end of life of an insulation material to transformer life, mentioning that he has never seen a transformer operate at 110 C (temperature index of current industry proven insulation system) for 20 years. He also discussed his experience with very old transformers with extremely brittle insulation that were still operational when taken out of service. - Alan mentioned a study by Duval that dielectrics are still OK when mechanical strength of cellulose insulation material was very low. Thus, perhaps having movement of the material, representing for example movement from a short circuit could be considered in the test. - Question was asked what defines end of life. Roger mentioned that it is defined relative to the Industry Proven System. Patrick McShane added that there are lots of ways to evaluate end of life, including lightning impulse, short circuit, switching surge, etc. Rogerio Verdolin mentioned end of life of surge arrestors, as an example, and suggested perhaps a ‘fingerprint’ of a transformer that could be tested new and over lifetime. - Patrick mentioned another ‘pothole’ with aging testing is moisture, and that high moisture in an aged unit can cause failure, and thus would like moisture to be included as part of the test. Alan added that regarding moisture and PRDs, that PRDs are usually set higher than the vapor pressure at test temperatures, and thus if this test procedure has PRD pressure that is lower, then moisture and other degradation products are lost, which these should be kept inside as much as possible.
Path Forward
The Chair then reviewed his proposed path forward, as follows: · Need to work on items discussed from these presentations for creating a draft revision. · Need volunteers for leading work in the areas mentioned: o #1 - Update Industry Proven System listing o #2 - Outline Location of test methods for draft o #3 - Sealed tube method improvement § Ratios, Pressure, Sample treatment, etc. o #4 - End of Life § Correlate to C57.12.00 curve, life requirement, EOL criteria
Discussion that followed included: - Bruce Forsyth proposed that 4 task forces be formed to address these 4 work areas. - Luiz added that it is important that end-users / utilities be involved in these task forces as well. Roger added that he & Kevin Biggie would review the roster & propose potential end users for participation. - Bruce made a motion to form the 4 task forces as proposed. Casey Ballard seconded the motion, but added a friendly amendment to set a deadline for the Task Forces to provide their recommendations at the next meeting. The motion as amended was approved unanimously. - Radoslaw Szewczyk suggested the life criteria of the liquid should be considered, as the standard currently focuses on the solid insulation. Roger added that the IEC test that is similar to this document (62332) attempts to discuss evaluation of the liquid as well as the solid in aging. Alan added that work is being done on aging of liquid as part of a task force under WG C57.154.
Page 6 of 17 Annex H
- Jinesh Malde cautioned that the testing in this test standard has to be practical to do, and that it should recognize testing that has been done in the past as valid.
Full list of task force volunteers collected during the meeting is as follows: #1 - Update Industry Proven System listing Task Force Lead – Roger Wicks Volunteers – Kevin Biggie, Israel Barrientos
#2 - Outline Location of test methods for draft Task Force Lead – Alan Sbravati Volunteers -
#3 - Sealed tube method improvement (Ratios, Pressure, Sample treatment, etc.) Task Force Lead – Jinesh Malde Volunteers – Evanne Wang, Mike Shannon, Jon Karas, Radek Szewczyk, Ed Casserly, Kevin Biggie, Andy Holden
#4 - End of Life (Correlate to C57.12.00 curve, life requirement, EOL criteria) Task Force Lead – Luiz Cheim Volunteers – Mario Alonso, Eric Doak, Rogerio Verdolin, Darrell Mangubat, Sasha Levin
The Chair concluded by mentioning that he will distribute the existing standard as a Word document to serve as Draft 0 prior to the task forces making recommended changes. With a motion from Alan, seconded by Vinay Mehrotra, the meeting was adjourned at 10:40 pm.

Discussions on Draft Document D2 (circulated before the meeting) A. Distribution Transformer loading: This topic is being discussed by the Transformer Efficiency and Loss Evaluation SC under SC Distribution. The chair will continue to maintain contact with Phil Hopkinson for input if made available. B. Table 8 Maximum Loading Multiplier (9.2.1)
Page 7 of 17 Annex H
· Mickel Saad suggested changing it based upon transformer size like in IEC with an insulation life of 180,000. He and Jeffrey Wright agreed to work on studying the IEC guidelines. · Don Platts suggested we make changes to temperature limit tables. · Daniel Blaydon mentioned that many utilities may not agree in to doing that. · Jeff Wright was inclined to limit maximum loading to less than 200% due to increased stray flux heating at the load. · Anastasia O’Malley stated that she was not in favor of changing limits since their 93-300 MVA transformers are designed on that basis. · Weijun Li mentioned that 200% overloading is used in the operating procedures of many utilities. · Daniel Blaydon wanted to know why there is reluctance to make changes to the limits. · Mickel Saad felt that utilities should be specifying a load profile during the overloading conditions in their purchase specifications. · Thomas Spitzer cited that Texas Utilities had a 150 % limit for overloading large power transformers. · Shibao Zhang commented that bushings did not have a short time overload rating · It was decided that Jeff Wright / David Wallach / Mickel Saad will work on a proposal for Table 8.
C. Updates to Ancillary Component loading (9.2.2) – Weijun Li · Weijun commented that we should revise 9.2.2 to state that design reviews should be held to ensure that the ancillary components are selected appropriately to withstand the overloading. It should also be called out in clause 9.7 · Juan Castellanos felt that the clause 9.2.2 is not meant for the transformer OEMs but rather for the users. · Bruce Forsyth felt that the design review intent is already conveyed in clause 9.2.2. · Thomas Spitzer felt that the OEM should be responsible to ensure the ancillary component capabilities. · Amitabh Sarkar felt that the user should specify the overloading requirements in the purchase specification. · Weijun Li mentioned that the intent was to make the user to take into consideration that the components will not be hot spot during the overloading cycle. · It was decided to leave the clause 9.2.2 as it was for now.
D. Updates to Effect of Loading Above Nameplate – Bushing (B.1.1)– Shibao Zhang · The temperature limits for overloading C57.19.100-2012 have been removed since bushings have zero overload capability. Based upon this, he proposed revision of Annexure B.1.1 of the guide to let the OEM / User decide the rating of the bushings based upon the specified overload. · Daniel Blaydon suggested we coordinate changes with the bushing overload TF. Peter Zhao mentioned that the concerned TF is getting ready to conclude its findings. They are working on PD / bubbling of condenser bushings due to overloading. · Robert Thompson requested that the guide only indicate that the users need to specify the current rating of the bushings. · Cihangir Sen stated that a number of design factors will change if overloading is specified.
E. Other Updates – A new/updated Abstract and Keywords were proposed by Barrie Kokanos via correspondence with the chair. Barrie was unable to attend but requested to participate with the WG.
Page 8 of 17 Annex H
Abstract: The contents of this guide describe the assumptions, techniques and methods for estimating the effects of loading above nameplate of 65 °C rise mineral-oil-immersed power transformers and step voltage regulators. Consequences due to loading above nameplate ratings are discussed including damage to insulation, production of gases in oil, and ultimately loss of life effects. In addition, effects of loading on auxiliary equipment is presented. Different types of loading scenarios as well as variations in ambient temperature and altitude are described. Effects due to different cooling techniques and their impacts on transformer capacity are reviewed. Transformer temperature criteria are also provided. Finally, two calculation methods with and without consideration to duct oil effects are provided and with sample temperature calculations.
Keywords: distribution transformer, step-voltage regulators, IEEE C57.91, loss-of-life, short-term overloads, long-term overloads, loading, mineral-oil-immersed, insulation aging, power transformer.
The sub-committee could not discuss this topic for want of time.
A. Differential Equation Presentation in Clause 7 and Annex G – Oleg Roizman made an excellent presentation on the history of this differential equation. He mentioned that there is a Cigre Publication # 659 for thermal modelling. Oleg will work on some suggested wording, perhaps an appendix, to propose at the next meeting. He recommended that a numerical solution today is more appropriate, using finite differences, to reflect better the performance of the transformer.
Additional notes from subcommittee meeting: Jim Graham asked if the presentation done by Oleg Roizman on Differential Equation would be available and the WG Chair mentioned that it would be posted on the website. Sanjib Som asked if the presentation could be made to a tutorial and Oleg was interested in making it into a tutorial. Tom Prevost would consider it for the Fall 2019 meeting if Oleg can contact Tom.
Working group on C57.119 IEEE Recommended Practice for Performing Temperature Rise Tests on Oil-Immersed Power Transformers at Loads Beyond Nameplate Ratings – Gael Kennedy
New revised standard published on October 18th 2018
Working group on C57.169 Maximum Winding Temperature Rise in Liquid- Filled Transformers (PC57.169 replacing IEEE 1538) – Scott Digby
The WG for Revision of the Guide for Determination of Maximum Winding Temperature Rise in Liquid- Immersed Transformers met on Tuesday, March 26, 2019. This new standard will be replacing the existing Std. 1538 that will be expiring in 2021. The PAR for this WG has been approved in March 2019 and will expire on December 31, 2023. This was the first meeting of the WG. The Chair Scott Digby called the Group to order at 1:46 PM. Two rosters were passed to obtain the membership requests from the attendees. According the rosters, there were total of 62 individuals present. 38 participants requested membership and became members since this was the first meeting of the WG.
The Chair initiated the meeting with presenting the Agenda. No approval required for the Agenda since this was the first meeting of the WG.
Page 9 of 17 Annex H
The Chair made the requisite Call for Patents and there were none noted by those present. An overview of the scope and the purpose of the WG were also reviewed. Some background information was provided to the attendees on the current IEEE Std. 1538 document and the Ammendment-1 that was published in 2015. The Chair also shared the comments that were received from the ballot resolution group during the reaffirmation of the standard during 2011. Some of the items were also reviewed and discussed during this meeting. The Chair opened the floor for discussion about the content of the Std. 1538 and the Amendment-1. Below topics were discussed during this session: 1) The Section 4.1 of the Amendment-1 is reprinted with the permission of CIGRE. Scott Digby (Chair) questioned if we should renew the permission from CIGRE to use the same section in the new standard C57.169. Gary Hoffman (APT) mentioned that any copyrighted material should go to the permission process before it goes in the draft. The Chair will contact Malia Zaman to start the permission process with CIGRE. 2) Peter Heinzig (Weidmann) commented about the similarities between C57.165 (Guide for Temperature Measurements for Liquid Immersed Transformers and Reactors) and C57.169 scopes. Some of the attendees also agreed that the direct winding temperature measurement methods are planned to be a part of the C57.165 guide. It was agreed to ask the subject to the other group’s Chair (Phil McClure) and make sure the subject is not a part of both WGs. The Chair volunteered for the task of contacting the other WG and discuss the similarities between both. 3) “Direct temperature measurement by fiber optic detectors” section does not include shell type transformer applications. Scott Digby (Chair) volunteered for contacting some of the shell type manufacturers to ask about their direct hot spot measurement methods (how many probes, how to install, where to install the fiber optic probes, etc.) and the need to add such content to the document. 4) Gary Hoffman (APT) suggested that a latest version of the Std. 1538 and the Amendment-1 to be submitted to the members of the WG. The Chair will be submitting the documents to the members. 5) Juan Castellanos (Prolec GE) mentioned that the new IEC Loading Guide has an Annex regarding direct hot spot measurement by fiber optic probes written by Hasse Nordman. WG will review this section and discuss if there is any information that could be implemented in the new standard. 6) The Chair asked the WG if there are any volunteers who are willing to review the current standard and provide their feedback. Below attendees have volunteered for reviewing and assessing the content of the document related to direct measurement by fiber optic probes (section 4.1 and Amendment-1): · Surinder Sandhu (Consultant) · Peter Heinzig (Weidmann) · Suresh Babanna (Southwest Electric Company) 7) The Chair asked for other volunteers who could help with reviewing some of the sections of the Std. 1538. · Jason Varnell (SPX) has volunteered for reviewing the Section 3 “Definitions” to make sure the definitions are matching the other IEEE documents. · Juan Castellanos (Prolec GE) has volunteered to review the below sections i. Section 4.3 “Prototype test data” ii. Section 4.4 “Test windings”
Page 10 of 17 Annex H
iii. Section 6 “Determination of hottest spot rise….” with Annex-C 8) A question was asked if the new standard will be including only the oil filled transformers. The Chair presented the scope of the WG and verified that the standard will be only for the oil filled transformer applications. 9) Juan Castellanos (Prolec GE) mentioned that the average winding rise shouldn’t be in this WG’s scope since it is already covered in C57.12.90. The Chair agreed to that comment and there was general consensus to that viewpoint. It was further clarified that our work can include up to what is stated in the scope. 10) Several attendees from transformer manufacturers mentioned that the direct measurement method by thermocouples is used for special applications and not being used for measuring the temperature during the acceptance tests of the transformers. Don Platts (Chair of Std. 1538) has provided some background information about Section 4.2 “Direct measurement by thermocouples”. Prior to the development of testing with fiber optics, all the thermal evaluations were done on models with thermocouples. He said that section about thermocouples is a carryover from the traditional methods before measurements with fiber optics so WG might want to consider eliminating this section. Juan Castellanos, Gary Hoffman and Craig Stiegemeier shared some special applications that were performed by using thermocouples such as prototype bushing and winding temperature measurements. Jason Varnell (SPX) pointed the last paragraph of Section 4.2 that clarifies the thermocouples to be installed temporarily in the distribution transformers: “Due to the voltage hazard, the thermocouples must not remain if the transformer is placed in service”. As section 4.2 seems apply mainly to distribution transformers but there did not appear to be representation present with the current, relevant involvement, the Chair noted the need to reach out to the Distribution Subcommittee. Gary Hoffman volunteered to announce such during New Business at the Distribution Transformers Subcommittee meeting.
The subject will be discussed with other groups and will be clarified in the Fall 2019 meeting.
The Chair requested to receive the feedback from all volunteered members for reviewing the document until early August 2019 to make sure all are captured in the Fall 2019 meeting in Columbus, OH.
The next meeting of this WG will be during the Fall-2019 IEEE Transformers Committee Meetings in Columbus, OH.
The meeting was adjourned at approximately 2:48 p.m.

Chairs remarks
Page 11 of 17 Annex H
The Chair discussed the challenges the working group has experienced achieving a quorum the past couple of meetings. Meeting minutes for the 18-01 and 18-02 meetings were distributed via email but approval of the minutes using email was not successful due to a lack of response.
Attendance · Introduction of Members and Guests · Roll Call of Members for Quorum – 16 of 35 members were present. · We were informed during the roll call that one member had switched industries and will no longer be attending. That makes attendance 16 of 34 members present. · RFID system indicated agreement with initial roll call; 16 of 35 (34) members were present (Quorum not achieved) · Attendance Rosters were distributed as a backup to RFID. Roster attendance indicated 52 total in attendance. · One member showed up after the RFID session had closed so he is not documented in the RFID system but was documented in the meeting attendance · Members – 17, Guest – 12, New Guests – 23 · Quorum was achieved about 45 after the meeting was called to order. See agenda and minutes paragraph below.
Old business The Chair asked for volunteers for sections that weren’t previously covered: 1) Annex A Sensors. Gilles Bargone volunteered. 2) Annex B. Winding temperature indicators - Zan Kiparizoski volunteered. 3) Sections Still Needing Authors 4) Section 4.8 Bushing Temperature Measurement. No volunteers were identified during the meeting. 5) Section 4.9 Tie Plate Temperature Measurement. No volunteers 6) Section 4.10 Tap Changer Lead & Contact Temperature Measurement. No volunteers 7) Section 4.11 Bolted Connection Temperature Measurement. Hakim Dulac volunteered · Comment was later that this was raised more as a design test than something to monitor in service
New business Review of section drafts that have been completed 1) Definitions: Oleg Roizman - Not present to discuss. 2) Winding temperature section 4.3 3) Reviewed proposed changes to the draft of this section. No objections. Changes will be accepted as written. 4) Core Temperature Section 4.4 5) Reviewed proposed changes to the draft of this section. No objections. Changes will be accepted. 6) Additional areas for improvement were identified for the core temperature measurement section. · Recommendation was made to add information on how to install fiber sensors in the core. Gilles Bargone volunteered 7) Sections that don’t have volunteers – we will need to consider dropping sections that do not have adequate support. 8) One member commented that the word “shall” should not be used in this document since this is a guide and not a standard. Instances where “shall” is used should be reviewed. 9) Request was made to have a fiber manufacturer present to the group on best practices for what to measure and how to install fiber probes.
Page 12 of 17 Annex H
· Cigre has a guide for installation of fiber probes – this could be a start. 10) The chair requested a fiber optic temperature user review the section on fiber temperature measurement – Jamil Kahn volunteered

Working group on C57.154 Design, Testing and Application of Liquid-Immersed Transformers with High-Temperature Insulation – Richard Marek
125 signed in, 136 recorded on RFID. Had quorum 50 of 90, 5 requested membership. Agenda and meeting minutes from last meeting approved. A TF was formed to evaluate “Thermal Class of Insulating Liquid” since 3 meetings. A test was presented. David Stankes revised the definitions. Definition of reference temperature needed to be aligned to 1280. Kurk Kr suggested to provide cooling stages for hybrid insulation. Radik proposed for content for information Annex for guidance for high temperature applications. Phil Hopkinson provided information on contents. Brough discussion of connection made on bolt or crimp. Rainer Froscher brought questions on tap changers. A tap changer for high temperature application should meet exact same requirements for mineral oil. There should be no derating.
The meeting was called to order at 4:45PM on Monday March 25th by Chair Richard Marek. Vice-Chair Anastasia O’Malley and Secretary Ewald Schweiger (writer of Minutes) were also present.
This was the second meeting as a WG. There were 5 of the total 125 attendees that requested membership. There were a total of 125 people that signed in on the paper roster and 136 on the RFID list. The chair stated at the beginning of the meeting that the paper roster will lead since there have been previous issues with RFID system in this room.
Page 13 of 17 Annex H
Data from the RFID system: (versus paper roster) Number of Members in Activity = 90 Number of Members Present = 49 (50) Quorum Present = 54.4% Number of attendees = 136 (125) The following participants indicated interest to be a member: Frotscher Rainer Maschinenfabrik Reinhausen Galhardo Leonardo DuPont Kazmierczak Jerzy ABB Inc. Sankarakurup Dinesh Niagara Transformer Bradshaw Jeremiah Bureau of Reclamation
Introductions of the Chair, Vice Chair, and Secretary were made. Due to the large number of attendees no individual introductions were made. Attendees were asked to indicate their affiliations when making comments or asking questions. The patent slides were shown with no response. The chair presented the agenda and a motion was made and seconded to approve the revised minutes of meetings (Samuel Sharpless, Phil Hopkinson). There were no objections. The chair stated that the previously mailed minutes of meetings were re-arranged to Rev 2 and some administrative additions were added, including the list of names of participants. A motion was made and seconded to approve the revised minutes of meetings (Robert Thompson, Kurt Kaineder). There were no objections.
In the last meeting a TF was formed under the leadership of Alan Sbravati to investigate the thermal class of liquids. This TF have met via web meeting three times and the result was reported by Alan in this meeting. Alan reported the outcome of these meetings and presented a proposal for screening tests which could be performed with different types of liquids (mineral oil, natural and synthetic esters) at different temperatures. Tom Prevost shared his experience made in WG Moisture in Insulation PC57.162 and suggested that IFT (interfacial tension) be added to the list of tests as well.
Dave Stankes (supported by Jose Silva) presented the result of the comparison of definitions in IEEE C57.154 with those in C57.12.80 (also under revision) to determine if there are any conflicts.
Only one minor conflict was found with the definition of reference temperature. A motion was made by David Stankes to align the reference temperature definition of C57.154 with the one found in C57.12.80. This motion was second by Phil Hopkinson and it was approved by the members.
Radoslaw Szewczyk reported on the “Precision Needed for High Temperature Insulation System Description” and made suggestions to unify the notes of table 4 and to add a clarification for such case in the document, in section 4.2.4
Kurt Kaineder presented a slide with suggestion to add the cooling stages to table 3 - Maximum continuous temperature rise limits for transformers with hybrid insulation systems, to show the effect of cooling type (ON, OF, OD, the effect of liquid temperature class and the effect of combination of Insulation systems, cooling type and liquid thermal class.
Page 14 of 17 Annex H
Radoslaw Szewczyk proposed content for an informative annex: “Guidance on High Temperature Transformer Applications” and will send a draft before the next meeting.
On the topic Phil Hopkinson shared his findings of different behavior of contacts made out of different materials (e.g. silver and tin plating) and he reported the findings of his investigations on the behavior at high temperature in different liquids. This information is found in an annex in C57.157. The chair asked Phil to send a proposal for a wording as reference to this annex. Phil brought up another topic in regard to how the connections are done – bolted vs crimped – and the behavior at high temperatures. The chair asked for volunteers to share their experience on crimped connections under high temperature.
Rainer Frotscher presented questions a tap changer manufacturer needs to get answered to develop appropriate equipment. In coincidence with the floor the chair stated that the life of a high temperature transformer is assumed to be the same as for conventional mineral oil applications (180 000 hrs). The other questions remain as subjects for further discussion..
The chair announced that he will distribute all the presentations and suggestions shown in the meeting.
The WG plans to meet at the Fall 2019 Transformers Committee Meeting in Columbus, OH. The meeting was adjourned at 5:45PM.
Taskforce on Temperature Rise Test Procedures (C57.12.90 Clause 11) – Ajith Varghese
TF meeting on Temperature Rise Test Procedure C57.12.90, Clause 11 started at 8:00 AM on Tuesday, March 26 in El Capitan room of Hilton Anaheim Hotel, Anahein, California.
This was the first meeting of this task force and hence there were no official member registered for this task force.
TF chair asked for volunteer to work as Secretary for this TF and Arup Chakraborty from Delta Star agreed to work as Secretary for this TF. There were 78 participants, 64 requesting membership and all were granted. Attendance was recorded in AM System.
Jerzy Kazmierczak of ABB presented test data showing the difference of tested winding gradients with respect to time to hot resistance shutdown, which shows no significant difference in winding gradient measurement for hot resistance shutdown taken at 30mins, 45mins & 60mins.
Egon Kirchenmayer of Siemens presented theoretical estimation of winding time constant and suggested that time to hot resistance shutdown can be set at 2-3 time of estimated winding time constant.
Ajith Varghese from SPX also presented measured winding gradient data from hot resistance shutdown taken at different time, which also shows insignificant difference in measured winding gradient taken within reasonable time e.g. 30mins, 45mins & 60mins.
The group agreed that work should be done to review the requirement of the time to hot resistance shutdown based on winding time constant in order to reduce temperature rise test duration and accordingly a draft will be prepared to present on the next meeting.
Meeting adjourned at 9:10 AM

H.4 Old Business
There was no old business
H.5 New Business
1) Jin Sim forward the following proposal to the Chair electronically: C57.12.90-2015 Clause 11.1.2.2 d) and e) requires holding the current constant for 1 hour. This work was taken over by TF Chaired by Ajith Varghese
In the Standards meeting, Steve Antosz mentioned that ILSC continues working on reviewing the Temperature measurement in the C57.12.90. Ajith will complete the work for the TF looking at C57.12.90-12 Clause 11.2.2 d) and e) and once the work is complete, Bob Thompson will Chair the TF for continuous revision of the temperature rise test in C57.12.90. Bruce Forsyth made the motion to “form TF for continuous revision of temperature rise test in IEEE C57.12.90 upon completion of the TF currently reviewing the C57.12.90-12 Clause 11.2.2 d) and e)” .The motion was seconded by Jim Graham.
2) Alan Sbravati suggested that a TF be formed to determine if a guide is required for retrofilling mineral oil transformers with alternative liquids.
ILSC Chair did not believe that the guide would belong to the ILSC. It would be more suited for Insulating Liquid SC. Tom Prevost mentioned that there is an active PAR for C57.166 (Acceptance and Maintenance of Insulating Liquids) that will look at mixing of liquids. He believes that it should be Insulating Liquid Subcommittee and looked at by the WG in C57.166. It was concluded that this discussion be brought forward in the Insulating Liquid Subcommittee meeting.
New Topics 1) Joe Watson representing Volts/Hz TF in the Power Subcommittees had new business. 2 years ago transformer committee was asked if there were recent V/Hz curves for relays. An investigation took place to look at what information was there. The outcome from the investigation was that one curve used by everyone was not valid anymore. The TF intends to develop new processes to establishing V/Hz capability curves for transformers. These transformers would be directly connected to generators. The group is talking about 10s to 2 min period of time where there would be load rejection or abnormal conditions where there would be high V/Hz. The TF need support from this subcommittee to get expertise in damage on insulation. The TF want to make sure that there is coordination. Joe mentioned that the TF on V/Hz can report back to ILSC.
2) Jim Graham who was speaking as Vice Chair of Terminology Standard PC57.12.80 is looking for volunteers to review the standards to align definitions. Looking for people from ILSC to review the standards and guides under ILSC for definitions that need to be added, deleted or modified. If anyone is interested, they should contact Clair Clairborne and Jim Graham. Shankar Nambi volunteered on behalf of ILSC to look at the standards and aligning the definitions to PC57.12.80 document.
H.6 Adjournment
With all business completed, the Chair called for a motion to adjourn. Hemchandra Shertukde moved for adjournment and the motion was seconded by Phil Hopkinson. The meeting was adjourned at 9:03 AM.

Sahin Testing the transformer with the same liquid as it would have in service will be handled by a task force under standards subcommittee. Continue updating section 12.3.4 for the number of short circuit tests. A new business was agreed to be worked on to update the section 7.1.2 Voltage and Frequency of the ratio test to give a larger bandwidth for the acceptable frequency.
2) WG Guide for FRA for Liquid Filled Transformers C57.149 C. Sweetser
Page 6 of 24 Annex J
A brief presentation was conducted on recommended FRA measurement test parameters. More specifics about grounding practices should be discussed. Input from SFRA equipment manufacturers for their recommended practices. Discussion about frequency limits. Test connections diagrams. Possible vector diagrams for the open circuit tests. Analysis section it would be helpful to end users to know if they have a problem by calculating indices which are the interpretation of the difference between two curves so they can see a “number”.
3) TF on Audible Sound Revision to Clause 13 of C57.12.90 R. Girgis The first item presented was the proposed revisions to Table 17 and Annex C in C57.12.00 which were recently approved through Survey at the PCS Subcommittee level. These items were recently submitted by the Chairman to Mr. Steve Snyder to be included in the 2020 Revision of C57.12.00. A new survey was issued to TF members on proposed text on “Impact of temperature on core noise” and on “Impact of temperature & tap position on load noise” to be added to Clauses (13.3.3.1 No-load audible sound level) and (13.3.3.1 load audible sound level); respectively.
4) WG on Loss Measurement C57.123 E. teNyenhuis The Chair presented all comments received from the PCS survey sent out after the Fall 2018 meeting. It was generally agreed that the draft guide is complete. The chair made the motion that PCS approve to move forward the C57.123 draft guide on for balloting. The motion was made by Ed teNyenhuis and seconded by Ramsis Girgis. It was approved unanimously by the SC.
5) TF on PCS Continuous Revisions to C57.12.00 T. Ansari Motion # 1 - Add details on the specific type of core on the nameplate • Type 2, 3, or 5 limb Core • Design = Shell or Core type It was approved unanimously. Motion # 2 — A change in the definition of rated current was approved by the Task Force with the following recommendation: Proposal: To modify the requirements noted in the comments column for the impedance voltage and load loss tests in C57.12.OO Table 17 as follows: Current: These measurements shall be taken only at the rated voltage connection for a two-winding unit, and at all rated voltage connections for units with three or more windings. Proposed: These measurements shall be taken only at the rated voltage connection for a two-winding unit, and at all rated voltage connections for units with three or more windings. At least one test shall be performed at the minimum kVA rating and one test at the maximum kVA rating. Result of the motion: Objections: 8, Abstention: 7, Approval: 45
6) WG on Amendment to Neutral Grounding Devices PC57.32a S. Panetta The meeting was great. There were people from Turkey, England, Mexico, and the US. The WG is planning to conclude the document in a couple of months. The WG will re-circulated the draft.
7) WG Shunt Reactors C57.21 S. Som The draft 4.2 of the document is now in the balloting process, closing on March 27, 2019. There are no plans to extend the ballot closing date.
Page 7 of 24 Annex J
The Chair requested additional volunteers to join the BRG: Mike Sharp, Dharamvir and Ulf Radbrandt have volunteered to the BRG. Next step is to resolve the comments and recirculate the document. Target date is end of May 2019.
8) WG on C57.18.10 Semiconductor Rectifier Transformers S. Kennedy Discussion of Draft 5 Revisions: Draft 5 had a 73.3% WG Survey approval, but with comments. There were several discussions regarding if FEA should be required for strays and eddies. The chair committed to reviewing the IEC standard and proposing text for C57.18.10 to be circulated for online voting. Draft 5 had no negatives but several comments that need to be included in Draft 6 for a WG survey. If this survey, which will be conducted in a month or two, is successful we would like PCS permission to move on to submitting an IEEE ballot.
9) WG on HV & EHV Breaker & Transformer Sw. Transients C57.142 J. McBride The present draft of the Guide is posted on the Working Group website. Review of C57.142 Draft 6: The chair requested that the members and guests please continue to review and comment on the existing draft over the next few weeks before the draft is handed to the IEEE Switchgear Committee for review. Mitigation Methods Task Force Update: The Chair added that more communication is required between the end-user of the transformer and the manufacturer with regard to the potential for exposure to high- energy transients in the field. Multiple mitigation methods are also being discussed and will be addressed in the Guide. Switchgear Liaison Update: The C57.142 Guide is a co-sponsored document between Switchgear and Transformers and run by Transformers Committee. The next IEEE Switchgear Committee Meeting will be held April 28-May 2, 2019 in Burlington, VT.

J.8.2 WG Guide for FRA for Liquid Filled Transformers C57.149 Title: Guide for the Application and Interpretation of Frequency Response Analysis for Oil- Immersed Transformers
Page 9 of 24 Annex J
Working Group “Guide for FRA for Liquid-Filled Transformers” C57.149 (Performance Characteristics Sub-Committee) Meeting Date/Time: March 25, 2019 1:45 PM Meeting Location: Capistrano A – Hilton Anaheim Chairman: Charles Sweetser [CS] (Omicron) Vice-Chair: Poorvi Patel (EPRI) Secretary: James Cross (Kinectrics) Meeting was convened at 1:45 PM by Chairman Charles Sweetser with 56 total attendees, consisting of 11 members and 45 guests. The WG achieved a quorum. Charles Sweetser reviewed the standard patent disclosure info. Peter Werelius made a motion to approve minutes and agenda. Mario Locarno seconded. Carried unanimously. Review of Suggestions: 1. Scope/Application – Steve Schappell (SPX Transformer Solutions) 2. FRA Test Parameters – Peter Werelius (Megger) 3. Making an FRA Measurement – Diego Robalino (Megger) 4. Test Records – Alex Kraetge (Omicron) 5. Analysis & Interpretation • Mario Locarno (Doble) • Luiz Cheim (ABB) • Hemchandra Shertukde (UHart) • Peter Werelius (Megger) • Mark Lachman (Doble) Steve Schappell had not had a chance to prepare draft on scope and application.
Peter Werelius (Megger) made a brief presentation on recommended FRA measurement test parameters. He offered that the document should be updated to make more specific recommendations. It also needs more specifics about grounding practices. Peter will offered to prepare some words around these topics, but he is looking for input from other SFRA equipment manufacturers for their recommended practices. Mario Locarno volunteered, and Charles Sweetser offered to provide grounding information to Peter Werelius. Discussion about frequency limits. Mario commented about the impulse guide frequency limits. Peter Werelius is suggesting 20 Hz to 2 MHz frequency range. Charles Sweetser, Mario Locarno, and Poorvi Patel agree to these limits. Charles Sweetser offered that some test cables (18 meters long) exhibit strange performance characteristics in the 1 – 2 MHz range. Poorvi Patel offered that the guide should differentiate between good and poor grounding practices and what the impact is on the response traces. Diego Robalino made a presentation on Section 4 on making a FRA measurement. 4.2 par. 5 safety consideration about excessive voltages in a combustible environment…should be defined. 4.4 par 1 and par. 2 – grounding practices. Ground loop verification. 4.5 par. 3 “insulated” vs “isolated” from ground. Test connections – Diego Robalino showed a table of possible vector diagrams for the open circuit tests. Roger Verdolin said that C57.105 has been recently approved and shows transformer connections and so can be used as a reference for vector groups. Peter Werelius noted the difference between IEC and C57.149 in terms of the test connections relative to the vector groups. Charles Sweetser offered that the test data should be organized phase A, B, C head to tail in a consistent manner to allow for easier data interpretation to aid in future data comparisons to baseline testing, the test connections must be clearly defined and recorded. Peter Werelius noted that test connections from previous test measurements should take precedence over connection diagrams in the guide (i.e. consistency in making connections is more important than what the guide might recommend).
Page 10 of 24 Annex J
Jason Varnel from SPX is working group chair for IEEE C57.12.70 and asked whether the FRA guide should follow that document. Should Diego’s information on connections and vector groups be included as an informative addendum to the Guide with examples? Poorvi Patel suggested that the information should be included for now and a decision made later as to whether it should be moved to an Addendum.
Mario Locorno (Doble) made a presentation on presentation on grounding topics and the quality of the grounding circuit. CIGRE interpretation guide is going to be published later this year and perhaps some of this information can be incorporated into C57.149. We would need CIGRE’s permission to do so. Luiz Cheim noted that we should not duplicate CIGRE info in our document and that hopefully we might incorporate new developments and algorithms for movement detection in our document (use of calculated indices). Charles Sweetser noted that we should focus on axial, radial and bulk winding movement. Peter noted that in the analysis section it would be helpful to end users to know if they have a problem by calculating indices which are the interpretation of the difference between two curves so they can see a “number”. Mario asked if there were new test techniques that have been developed that might help improve the test interpretation e.g. FRA ratio tests. Charles Sweetser asked for a volunteer to lead Section 5 (Analysis and Interpretation) by having a couple of meetings before the fall/2019 meeting. Peter Werelius volunteered. Mario Locarno will take the lead on the grounding issue with Peter Werelius and Charles Sweetser. Mario Locarno has not received any data from anyone on SFRA measurements to date. He volunteered to continue to shepherd the data gathering process. He may be contacted at [email protected]. Poorvi Patel noted that we were to create a template for the data collection. Poorvi Patel will check to see what was used in the CIGRE project. Motion to adjourn… Mario moved, Diego seconded. Adjourn at 2:50 PM. James Cross Secretary C57.149 WG
J.8.3 TF on Audible Sound Revision to Clause 13 of C57.12.90 Title: Standard Test Code for Liquid-Immersed Distribution, Power, and Regulating Transformers
Unapproved Minutes of Spring 2019 Meeting of TF “Audible Sound Revision to Test Code C57.12.90”, in Anaheim, CA The TF met at 1:45 PM, on Monday, March 25, 2019. Chairman Dr. Ramsis Girgis presided over the technical part of the meeting and Secretary Barry Beaster handled the administrative duties of the meeting. After the Fall 2018 meeting, the membership was adjusted to 48 members. This meeting was attended by 26 of the 48 members and 54 guests for a total of 102 participants. A quorum was established after the final attendance was recorded in the AMS system due to some initial issues with the Cloud-In-Hand badging system. During the meeting, a call was made for any objections for a tentative unanimous approval of the Fall 2018 TF minutes; no objections were raised so we have a post-meeting official approval. The proposed agenda was presented without objections for approval. The circulated attendance sheets had thirteen requests for TF membership; which will be reviewed based on previous meeting attendance.
Page 11 of 24 Annex J
The first item presented was the proposed revisions to Table 17 and Annex C in C57.12.00; which were recently approved through a Survey at the PCS Subcommittee level. These proposed revisions are as follows: § Incorporated NEMA TR1 Tables 1 & 2 for No-load sound levels into Annex – C with improvements (Tables C1 & C2) § Replaced the formulas presently in Annex – C, for calculating reference load Sound Power levels, with tables of corresponding Sound Pressure levels (Table C3) § Modified reference to the revised Annex – C in Table 17 These items were recently submitted by the Chairman to Mr. Steve Snyder to be included in the 2020 Revision of C57.12.00. Prior to this TF meeting, a survey was issued to TF members on proposed text on “Impact of temperature on core noise” and on “Impact of temperature & tap position on load noise” to be added to Clauses (13.3.3.1 No-load audible sound level) and (13.3.3.2 load audible sound level) in C57.12.90; respectively. The results of the survey had 14 returned ballots, 8 approved, and 6 approved with comments. The proposed text on “Impact of core temperature on core noise” was as follows: § Generally, core temperature has a small impact on core noise. However, cores made of core materials that have lower quality coating with lower surface tension have been seen to experience an increase in core sound level of several dBs at higher core temperatures. This is more noticeable for high loss core steels at high operating flux densities. Other than editorial suggestions, the main comments received on this proposed text are as follows: § Need for more quantitative description of words like: Small impact, lower quality coating, higher core temperatures, high loss core steels, and high operating flux densities § Wouldn’t such information belong to a Guide? § Is there a need to perform the core noise test at a higher core temperature? Based on some of the comments from the TF members, the following revised text was proposed in the meeting: “Generally, core temperature has no, or small (1 – 2 dB), impact on core noise. However; depending on the type of core steel and the core lamination coating, several decibels (dB) higher core noise levels are likely at core temperatures that are higher than design values”. The Chairman then opened the forum for a discussion of this item requesting feedback from core steel suppliers, transformer manufacturers, and transformer purchasers in attendance. Some of the main feedback received were as follows: § The present test code doesn’t state a temperature for the sound test, so, at what temperature should core noise be tested at? § Operating at 110 % voltage excitation at no load is part of the Standard requirements for transformer designs § Is the effect of core temperature on core noise the same when the whole transformer core temperature is higher during regular operation?
Page 12 of 24 Annex J
§ Since impact of core temperature on core noise cannot be defined better, perhaps this should be in a guide rather than in the Standard? § How is the magnitude of this “effect of temperature on core noise” dependent on the B800 value (value that defines the degree of magnetic grain orientation of core steel)? The Chairman answered to these questions / comments. He suggested that the TF will need to first understand how the magnitude of this effect, as observed at core noise test in the factory, compares with that when the transformer is in operation with the whole core temperature elevated. The Chairman also requested transformer manufacturers to conduct the following test in order to quantitatively evaluate this phenomenon: § Perform the no-load test at 110 % excitation and measure core loss & core noise over a period of 4 hours, record the measured values at intervals of 15 minutes for the first hour, and every hour for the remaining 3 hours. § Repeat the core loss & core noise test at 110 % excitation after the heat-run test (s) with the oil temperature elevated and compare measurements with the original measurements made at room temperature. § Perform above tests on transformers with cores made of core steels from different suppliers. The first priority would be to perform above tests on 3-phase core-form transformers with the 3- limb core and, if possible, perform the same tests on 3-phase core-form transformers with the 5- limb core type, and on at least one 1-phase transformer. Manufacturers are to share this test data with the chairman on a proprietary basis. No design information of these transformers will need to be shared with the Chairman. As the meeting time had expired, the meeting was adjourned at 3:00 PM. Respectively submitted, Ramsis Girgis, TF Chairman Barry Beaster, TF Secretary

Performance Characteristics Subcommittee IEEE / PES Transformers Committee
March 25, 2019 4:45 PM The Hilton Anaheim Hotel Anaheim, California USA
UNAPPROVED MINUTES
The PCS Task Force on General Requirements for C57.12.00 met on Monday, March 25, 2019. The Chair Tauhid Ansari called the Group to order at 4:50 PM and reminded purpose and scope of the TF. According to the automated RFID system, 48 Members and 60 guests were present. Paper rosters were distributed as a backup. The quorum to conduct regular business was established as 88 members are registered in the Task Force. The following 4 guests requested membership:
Alexander Winter HIGHVOLT Pruftechnik Dresden Christopher Slattery FirstEnergy Corp. Everton De Oliveira Siemens LTDA Zan Kiparizoski Howard Industries
The Chair introduced 5 new Members to the Group. The Jacksonville (Fall 2018) minutes were reviewed (correct spelling for Ryan Musgrove’s name) and approved (Amitabh Sarkar, Sanjib Son) by the Group. The Agenda was approved (Eduardo Garcia, Rogerio Verdolin) with no amendments. Agenda Items were covered as follows. Agenda was approved as written. Ryan Musgrove pointed a spelling correction of his name in minutes of meeting (Fall 2018). Chair corrected the minutes, and then the minutes was approved unanimously 1. OLD BUSINESS A. WG Item 110, Table 17: Daniel Blaydon (Baltimore Gas & Electric) proposed a clear definition of the “rated current” during load loss test. Discussion on the subject started in the Jacksonville meeting and was not concluded. A new proposed text was presented by Daniel and the Chair opened the floor for discussion. The new text requested measurement of impedance and load losses at minimum and maximum kVA rating of a transformer. It was questioned if dual voltage transformers would require measurements at each rated voltage, which would depend on users’ specification. Don Ayers pointed out to cases where test capacity does not reach for transformer´s maximum rating. S. Patel remarked that every transformer should be tested mainly at guaranteed kVA rating. Daniel brought up that other C57 standards call up for different kVA ratings for specific tests.
Sanjib Som explained that measuring at different kVA ratings can yield different losses, from unaccounted leakage flux effects, he proposed to add losses at maximum rating. Amitabh Sarkar pointed out that losses at maximum rating are currently measured for heat run test, although that is not a routine test. B. Yang recommended to set in Table 17 loss measurement at base rating, as measurement error can be magnified at higher currents. It was mentioned that the WG Continuous revision of C57.12.90 had also discussed the subject and proposal (not further explained).
Daniel Blaydon made a motion (second H. Shertukde) for a new text to be included in C57.12.00. An amendment was proposed to the motion and rejected by the Group, so the motion was voted with count of 25 members in favor, 8 opposed and 5 abstains. Chair will request PC Subcommittee to circulate the survey in PC subcommittee.
Page 15 of 24 Annex J
B. WG Item 111, change ratio tolerance to 1% or less than 1/10th of the transformer impedance. – Submitted by S. Hakim. The Chair passed discussion of the subject for the next WG´s meeting as Hakim could not attend this time.
2. NEW BUSINESS A. The Chair presented a question from Ryan Musgrove, regarding ratio tolerance on 3 phase power transformers. As C57.1.200 is written now, there could be a 1% difference between one phase and another. Example, a phase is -.49% and c phase is +.49 percent. Technically both are within 0.5% of nameplate voltage. The floor was open for discussion.
Jason Varnell mentioned that current tolerance should be considered acceptable, as long as explained, to avoid unnecessary rework. Ajit Varghesse pointed out that higher than 1% difference should be considered relevant for investigation. Lpizra Aymen explained that such a low difference between phase voltages can be relevant for specific projects. Ryan further explained that a 1% turns ratio difference between phases can imply several turns and have an impact on sensitive equipment. Sanjay Patel pointed out that allowable differences can have an impact for parallel connections.
The Chair proposed to continue discussion on the subject in the next WG’s meeting.
With no other new business brought up from the attendance, the meeting was adjourned at 5:55 PM (H.Shertukde, S.Som)
Respectfully submitted,
Tauhid Ansari Enrique Betancourt TF Chair Secretary

Working Group on Semiconductor Power Transformers – C57.18.10
Unapproved Meeting Minutes
Anaheim Hilton, Anaheim, CA California Ballroom B 11:00 am, March 26,2019
The Working Group met in the California Ballroom B meeting room Sheldon Kennedy called the meeting to order at 11:03 am and the group did introductions. There were 18 members and 35 guests/other present. A quorum was present (18 of 30 members). John John moved for approval of the agenda. Sanjib Som seconded. Agenda approved. The Pittsburgh minutes were approved by email vote. Sheldon asked for motion to approve Jacksonville minutes. Mike Iman so moved. Dhiru Patel seconded. Minutes unanimously approved. The patent call was given. Nobody replied with any patent issues.
Discussion of Draft 5 Revisions-Draft 5 had a 73.3% WG Survey approval, but with comments.
Review of online vote comments: Line 17, Pg19- Should we refer to C57.12.00 and C57.12.01 instead of C57.12.90 and C57.12.91? D. Walker was in favor of replacement. Vote was 17 in favor. No opposed. Motion passed.
Page 19 of 24 Annex J
Clause 10.2 Table 2 and 3- should refer to C57.12.00 and C57.12.01 rather than duplicate in C57.18.10? 17 in favor. No opposed. Motion passed.
8.6.2- Should FEA be required for strays and eddies? D. Walker suggest that it be “recommended” rather than “required”. Muhammad Cheema suggested that FEA doesn’t always work for foil, high current, windings. Subhas Sarkar suggested referring to old method. Sheldon suggested referring to Annex with old method in it. Sanjib Som wondered how we can require FEA since many different tools are available and produce different results. Don Ayers said we can’t require a specific program but should recommend a general type. Sanjib Som should we mention validating via test results. Sheldon suggested improving verbiage to improve clarity. Muhammad Cheema said that difference is how eddy are evaluated and how the program worked. Much discussion continued. Sheldon proposed looking at IEC standard requirements since they require FEA and see how it is stated. Subhas Sarkar suggested that FEA on every job is too time consuming and rules of thumb are useful for everyday use. Aniruddha Narawane thinks FEA discussion should be informative rather than normative. Sasha Levin reminded that C57.110 discusses stray and eddies in annexes. Don Ayers suggests that FEA is preferred and that in the absence of FEA other methods may be used. Sheldon committed to reviewing the IEC standard and proposing text for C57.18.10 to be circulated for online voting.
C57.12.51 title is incorrect and doesn’t match latest version. Similar to C57.12.01. Make sure that references match today’s title. Bill to update Draft.
Sheldon reviewed the sections of the Draft that had major revisions:
Traction Overload Definitions- 1653.2 is changing the definitions and they are different than C57.18.10. D. Walker moved that we remove the traction overload definitions from C57.18.10 and instead refer to 1653.1 and 1653.2 instead. Subhas Sarkar seconded. Approved unanimously.
Phil Hopkinson mentioned that some inverter/drive manufacturers short all secondaries of the transformer in a IGBT failure and then open a breaker. This creates a transient voltage in the transformer. At least two other drive manufacturers also do this. Phil to write up a note on this problem.
New Business: · No new business
With no further business, the meeting was adjourned at 12:05am.
The Working Group will meet again at the Fall 2019 meeting in Columbus, OH

IEEE / PES Transformers Committee Performance Characteristics Subcommittee
WG to Investigate the Interaction between Substation Transients And Transformers in HV and EHV Applications and Revision of C57.142
Anaheim, CA Tuesday, March 26, 2019 3:15 PM – 4:30 PM California Ballroom B Chairman – Jim McBride Vice Chair – Xose Lopez-Fernandez Secretary – Tom Melle
1) Meeting called to order at 3:15 PM. Welcome and Chair’s Remarks 2) Circulation of Attendance Sheets 97 Attendees were present (546Guests) 43 of 53 Members present (quorum was achieved) 3) No essential patent claims made 4) Approval of Agenda (motion by Pierre Riffon and 2nd by Deepak Kumaria) and meeting minutes from Fall 2018 (motion by Klaus Pointner and 2nd by Akash Joshi) without objection.
5) Status of Current Draft and Comments – Jim McBride The present draft of the Guide is posted on the Working Group website
Review of C57.142 Draft 6 – The Chair noted that editorial changes continue, but the WG members and guests have not provided many comments since Draft 5. Some additional editing / cleanup may be needed and continued review by the WG is appreciated. Additional examples are included in D6 (GSU in backfeed mode, failing autotransformers, instrument transformers, and reactor switching).
The chair requested that the members and guests please continue to review and comment on the existing draft over the next few weeks before the draft is handed to the IEEE Switchgear Committee for review.
6) Status of Task Force Paper – Jim McBride IEEE requested the TF paper be reformatted to include CV’s for the paper authors. This will be handled by WG Vice Chair Xose Lopez-Fernandez.
7) Mitigation Methods Task Force Update – Phil Hopkinson
In the past, EHV reactors that were failing in the field were passing factory test levels. Special Terminated Lightning Impulse Tests (STLI) were then incorporated and failures reduced dramatically.
Page 21 of 24 Annex J
Phil requested manufacturers data using RSG (recurrent surge testing) in order to understand the stresses on windings. Phil reminded the WG that many old transformers had electrostatic shields. Line shields increase series capacitance and greatly reduce capacitance to ground. In the past (for 34.5 kV and below) static shields added to the winding seemed to increase probability of surviving re-strikes
Shielding solves many issues with series resonance and is relatively easy to apply. The conclusion is that increasing the series capacitance and reducing the capacitance to ground should improve the design. Phil urged the group to focus on improving transformer designs and developing new test methodologies.
Mitigation methods with some success have included: higher BIL, open terminal special impulse test, and fast-front switching surge with a long tail time.
The Chair added that more communication is required between the end-user of the transformer and the manufacturer with regard to the potential for exposure to high-energy transients in the field. Advanced modeling will be necessary in order to mitigate these issues. Experts who can model/analyze disc and layer winding designs are necessary in order to move the WG efforts forward. Multiple mitigation methods are also being discussed and will be addressed in the Guide.
8) STLI Presentation by Mike Spurlock of AEP (will be posted on the WG website) using standard impulse waveforms (1.2 x 50 us)
Pierre Riffon asked if arrestors are used in the testing (on the X terminal) and if full voltage is applied on the H terminal. No arresters were used and full voltage was applied. Phil Hopkinson commented there was significant focus on the current traces in the presentation, but pointed out some significant collapse on the non-impulsed terminals. The chair commented that the significant point is how quickly the voltage appears on the non-impulsed terminals and that the arrestors are clamping.
Mike Spurlock added that the manufacturers tests show the stresses are higher and deeper into the winding than a standard impulse test. The chair added the STLI test better represents how the transformer is connected in service. Phil agreed this assessment matches prior failure modes and mitigation. Discussion by Amitabh Sarkar and others ensued regarding various testing arrangements (open versus terminated windings for example).
Manush Safar asked a question regarding whether an opening breaker versus closing breaker scenarios have been investigated and included in the Guide. Phil commented that different phenomenons (pre-strike and re-strike?) cause different stresses when opening or closing. The energy following a strike/restrike tends to move back-and-forth between the internal inductance and capacitance The Chair added that re-strike/re-ignition can cause severe issues and several examples are included in the draft guide.
Phil Hopkinson suggested shielded versus unshielded winding designs should be modeled and studied and further tested with the different STLI test configurations to gather more data. Mike Spurlock further commented that rather than arrester terminated, testing with capacitor terminated windings can be used to better simulate certain circuits (GSU’s for example).
9) Switchgear Liaison Update – Dave Caverly
Page 22 of 24 Annex J
The C57.142 Guide is a co-sponsored document between Switchgear and Transformers and run by Transformers Committee. The last Switchgear liaison meeting was held with 50 people present, There is now an official liaison TF between the Switchgear and Transformers committees. The next IEEE Switchgear Committee Meeting will be held April 28-May 2, 2019 in Burlington, VT.
10) JWG A2/C4.52 HF TDSF Modeling principles – Xose Lopez-Fernandez/Jim McBride TDSF for Transformer Modeling has been added to the monitoring circuit utilized by Jim McBride for High Frequency Transient Measurements.
Presentation topics included transformer modeling during Transformer Impulse Transients. Measured transients were then imposed on a detailed model of the transformer. The presentation will be posted on the WG website.

The Working Group for C57.164, the Guide for Establishing Short Circuit Withstand Capabilities of Liquid Immersed Power Transformers, Regulators, and Reactors:
Sanjay Patel – Chair, Raj Ahuja, – Vice Chair, Joe Watson - Secretary
The Working Group met Tuesday, March 26, 2019, 4:45-6:00 PM in the California Ballroom B with 31 guests and 22 of the 42 WG members present for a quorum. The agenda and minutes of the previous meeting were approved with no changes. The Patent question was asked with no responses.
A method of calculating short circuit forces was presented by Muhamad Ali Masood Cheema as a proposed addition to an Annex to the Guide. The method utilizes a flexible 2-dimensional model to calculate short circuit forces on windings. The details of the method were discussed and it was agreed to present a comparison of this method and the Andersen program and several other manufacturers’ methods at the next meeting. Volunteers from SPX, Hyundai and Smit agreed to help in these efforts.
The group voted to include the information on calculating short circuit currents, forces and stresses in the Guide. Whether all of these details will be included in the main body of the Guide or in Annexes, and the content of the force and stress sections has not yet been determined.
The group will meet again in Columbus.

Introductions of the Chair, Vice Chair, and Secretary were made. Attendees were asked to introduce themselves and indicate their affiliations when making comments or asking questions.
Chair Mike Spurlock introduced Poorvi Patel as the new committee vice chair and thanked Brian Sparling for this hard work and contribution to this working group.
Mike Spurlock also reminded the group that the PAR was approved in 2017 and expires December 31, 2021. That means we have 3 more meetings left to get this guide ready for balloting in December of 2020. We will need a year for balloting and commenting and this means the time is getting closer.
Mike Spurlock also recognized the numerous volunteers for all the work they have put into the revision and additions.
6 Annex K
A call for disclosure of any essential patent or patent applications claims was made. There were one patent claims identified.
A motion to approve the Spring 2018 Minutes was made by Joe Watson and seconded by Bill Whitehead. There were no objections or additions to the Minutes. There was no opposition to approval of the minutes.
A motion to approve the Fall 2018 Minutes was made by Joe Watson and seconded by Bill Whitehead. There were no objections or additions to the Minutes. There was no opposition to approval of the minutes.
An update on the working group activities around Chapter 5 work. 1. Bill Whitehead on the DGA, moisture, bushings, and GIC sections Bill is asking individuals for more support. The DGA portion is approximately 60% complete needing support in the fuel cell section for a technical and diagram. Volunteers are needed around solid state H2 sensor. The removal of the O2 sensor section was also discussed. Bill is also looking for installation and maintenance volunteers specifically around mounting, new/retrofit situations – Joe Watson offered to volunteer. Moisture looking at the .167 as terms to reference. Bushings need another last review. GIC is 60% complete and referencing the .163 guide instead of adding words to this guide. The question was asked about installation specifics for GIC. Luiz Cheim suggested including the sensors. Mike Spurlock volunteered to assist with the verbiage for the parameters to measure and type of sensors for GIC. AEP correlates GIC with transformer temperatures inside transformer. The use of a GEO-map instead of monitoring and use of calculations was also brought before the group. Luiz Cheim can assist this this. The NERC 007 standard was also brought up in this conversation. It was also noted that this standard assumes the transformer is young and in good working condition without considering the actual condition of the transformer.
2. Poorvi Patel’s update was on sections 5.1, 5.2, 5.3. They have had a couple of tele- conferences and almost complete with a need for volunteers to help. Section 5.1 (Winding temps) – need information and help with operating conditions, installation of sensor and maintenance requirements. Please reach out to Poorvi Patel to assist with this and it could be just a review of the existing wording from the old guide and simple refreshing only. Section 5.2 is in good shape. The installation section does it need to be here? What is the difference in the installation at the factory and the field? Section 5.3 is in good shape. Luiz Cheim and Poorvi Patel are reviewing it and this section does not need volunteers.
3. Emilo Morales-Cruz’s update section 5.4 (LTC) reviewed parameters on whole standard group them into sections. There is a need for volunteers around the motor drive control and several sections need to be reviewed to determine if needed. The .139 LTC gas guide was also brought up. The question of what is the difference between monitoring DGA
7 Annex K
online and does it need to be included? Since there are numerous vendors who have this technology it was suggested that this be added to the DGA section. Bill Whitehead noted that this should be as a reference to the values that can be monitored. This discussion was held between Luiz Cheim, Poorvi Patel, and Bill Whitehead and Poorvi Patel will review the LTC guide referenced earlier and give feedback on what to keep or take out of the LTC and DGA sections. Section 5.5 – transformer tank needs to be formatted. The PRD section is in progress with all areas assigned and formatting of words is mostly what is lacking. Also as a reminder, please make sure if given words from a supplier that permission is given in writing to use the wording and/or diagrams. We should not use any supplier internal material. Refer to standards lunch around this topic.
Mike Spurlock also noted that Chapter 4 is also under review. There is a new chapter #6 around asset selection, infrastructure, data collection and gathering. Also Chapter 7 need to be reviewed to determine if areas need to be removed. The appendix is also under review with updates needed. There was also mentioning of another new chapter for global manufacturing requirements.
The goal is to have a draft of the guide out for review by the Fall 2019 meeting in Columbus Ohio in October. There was no new business brought before the group.

TF on V/Hz Requirements
Kipp Yule – Chair, Ramsis Girgis, – Vice Chair, Joe Watson – Secretary
The Task Force on Volts/Hz Requirements met Tuesday, March 26, 2018, 3:15 – 4:30 PM with 10 of the 14 members present for a quorum and 30 guests. The Agenda was approved and there was no meeting in Jacksonville so no pending minutes to approve.
The Chair was unable to attend and participated remotely through a Skype meeting. Kipp Yule discussed the general purpose of the task force and then Ramsis Girgis gave a presentation on the origins and limitations of the commonly-used V/Hz curves. The presentation is attached to the end of these minutes. Most of the curves in use today are based on the original work done by William McNutt with GE in the 60’s. The data were obtained from a core form transformer design using standard cellulose-type insulation between the tie plates and core and is not accurate for other transformer designs such as shell-form types or core form designs using high temperature insulation.
Drew Welton also presented information related to V/Hz relay protection considerations and the challenges that relay engineers face.
The TF intends to develop a general process for manufacturers to use when establishing a V/Hz capability and damage curves that will be included in C57.116, the Guide for Transformers Directly Connected to Generators. The TF discussed the path forward and agreed that we should discuss the time/temperature limits that should be used for any new V/Hz damage curves with the Insulation Life SC and possibly others.
Joe Watson attended the Insulation Life Subcommittee meeting on March 27, 2019 and requested support to establish insulation damage criteria from short-time overheating and Jeff Ray volunteered to act as liason between the TF and the Insulation Life SC in this regard.
The TF will meet again in Columbus and intends to hold at least one web meeting before the Columbus meeting.

• Joe Watson emphasized the need for establishing a condition assessment guide. • Donald L, Mario L suggested the removal of word asset managers from the second paragraph. • Scott R felt the first paragraph was the scope and the second paragraph read more like the purpose. • Peter Zhao felt that big items should be excluded from the scope. • Jim Graham felt that the scope was sufficient to obtain a PAR and the purpose could be added later by amending the PAR. • Bruce F proposed that second paragraph be removed and first paragraph be adopted as scope. This was seconded by Scott R. • A vote was taken for retaining second paragraph as proposed by Joe Watson– this was voted down with 11-For and 32-Opposed. • Joe W moved a motion to withdraw his earlier proposal. • Then there was a suggestion and discussion to remove the words “development of indices” from the first paragraph. • Luiz Cheim felt the scope wording should include the word condition. • A vote on the scope without the second paragraph and deletion of the words “development of indices” from the first paragraph as follows: To present existing condition assessment methodologies that quantify the current condition of liquid immersed transformers, reactors and their components. • Vote passed with 41-For, 3-opposed and 4-absentees. • Joe Watson (Donald L seconded) proposed a vote to retain second paragraph as purpose. There were suggestions made to change the wording of the purpose as proposed. • After much discussion, it was decided to take a vote. 19 Annex K
• Vote did not pass with 16-for and 34-opposed. • Joe W moved a motion to withdraw his proposal to vote on a purpose.
Final Discussion: It was finally resolved that the Condition Assessment TF make the following recommendations to the Power Transformer sub-committee based upon the 41-3-4 vote as detailed above.
• Final Agreed Title (adopted at Louisville meeting):
A Guide for the Assessment of Liquid Immersed Transformers, Reactors and their components.

L.3 Working Group and Task Force Reports Standards Working Group on the Continuous Revision of C57.12.00
WG Chair: Steven L. Snyder
March 27, 2019
The purpose of this WG is to compile all the work being done in various TF/WG/SC’s for inclusion in the continuous revision of C57.12.00 in a consistent manner. This WG coordinates efforts with the companion Standard C57.12.90 so that they publish together.
The current standard was approved by the IEEE-SA Standards Board on December 5, 2015, with an official publication date of May 12, 2016. The standard is good for 10 years, but is under continuous revision and will be next balloted when sufficient new material is available. The PAR which covers the ongoing continuous work on the document is good through December 31, 2021.
As agreed at the Fall 2016 Standards Subcommittee meeting, any new material provide to me for inclusion in the next revision, will first be presented to this subcommittee for the “official” vote of approval. The following pages show two (2) new items that have been submitted to me for the next draft. Both have been fully vetted and approved by their respective subcommittees.
Based upon this and other work in process, I anticipate the next revision ballot to begin in 2020, with all the updates collected at the close of 2019.

6.8 Minimum external clearances of transformer live parts
Table 10 describes the minimum external clearances between transformer live parts to ground and to different phases. In the establishment of these clearances, it was recognized that bushing ends normally have rounded electrode shapes. It is also assumed that conductor clamps would be suitably shaped so that they would not reduce the withstand strengths, and the arrangement of the incoming conductors would not reduce the effective clearances provided by the transformer bushing. In other words, the clearances were established based upon electrostatic fields that were usually not divergent.
Where adequate previous experience has indicated that smaller clearances are acceptable, the smaller clearances may be applied when agreed upon by both the user and the manufacturer. The clearances in this section are for in service conditions. Factory test conditions may require larger clearances than those defined here. Minimum external clearances shall comply with Table 10 except where suitable grading of local stresses may allow smaller clearances. Any such reduction in clearances should be on the basis of agreement between user and manufacturer. The nominal clearance values indicated are subject to normal manufacturing tolerances. Normal manufacturing tolerances should not significantly increase the likelihood of a flashover because the clearances listed in Table 10 are conservative.

the table are based on lightning impulse. Clearances above 230kV in the table are based on switching impulse.
NOTE 2 – Transformers at nominal system voltages of 735kV, 765kV, and 1100kV are normally single phase so that clearances between live parts of different phases is not an issue. a The external clearances given are for transformers intended for operation at altitudes of 1000 m (3300 ft) or less. Refer to Clause 4.3.2 for operation at altitudes in excess of 1000 m (3300 ft). b Note that ANSI C57.12.34-2015 specifies a phase-to-ground clearance of 5.75 in (146 mm) and phase-to- phase clearance of 6.25 in (159 mm) for 125 kV BIL, 25kV nominal system voltage. ANSI C57.12.38- 2014 specifies a phase-to-ground clearance of 5.75 in (146 mm) for 125 kV BIL, 25kV nominal system voltage. The smaller clearances are acceptable since the bushings are always located within a metal enclosure and are not subject to the same conditions that occur with bushings exposed to the elements. cPhase-to-ground switching impulse clearances may be calculated using the following formulas. The values in this table were determined using a gap factor of 1.3, probability of withstand of 90%, and coefficient of variation of 7%. Refer to IEEE 1313.2 and IEEE 1427 for more information on these formulas.

L.3.3 WG Standards Transformer on Continuous Revision for C57.12.90 Standards Subcommittee IEEE/PES Transformers Committee WG Chair: Stephen Antosz March 27, 2019 INTRODUCTION This is a working group by committee of task forces, for continuous revision of C57.12.90. The purpose of the WG is to keep track of the work being done in various TF/WG/SC’s for inclusion in the continuous revision of C57.12.90 in a consistent manner.
Currently there are five Task Forces in three different Subcommittees, as follows: 1. PCS – Continuous Revision to Test Code C57.12.90 Clauses 5-9, & 12, TF Chair: Hakan Sahin 2. PCS – Audible Sound Revision Clause 13, TF Chair: Ramsis Girgis
Page 7 of 15 Annex L
3. Dielectric Test – Cont Rev to Impulse Tests in Clause 10, TF Chair: Pierre Riffon 4. Dielectric Test – Cont Rev to Low Frequency Tests in Clause 10, TF Chair: Bill Griesacker 5. Insulation Life – Cont Rev to Temperature Test Clause 11, TF Chair: Ajith Varghese/Bob Thompson
SUMMARY The revised document was published in March 2016 as IEEE Std C57.12.90-2015. Shortly after the document was published, one error and one omission were discovered, so a Corrigendum was done and published on March 23, 2017.
STATUS A new PAR was approved by NESCOM in December 2017, and has a life of 4 years.
We are planning to shut down work for this Standard (and C57.12.00 concurrently) at the end of this year 2019, and then balloting in 2020. So all Task Forces have until the October meeting and shortly thereafter to finalize their work outputs.
FUTURE REVISIONS AND PENDING WORK As agreed at the Fall 2016 Standards Subcommittee meeting, any new material provided by the various Task Forces to this WG Chair for inclusion in the next revision, will first be approved by the responsible technical subcommittee (Diel Test, PCS, Dist, IL, etc) and then presented to the Standards Subcommittee for the “official” vote of approval.
Since this is a continuous revision document, there continues to be ongoing work in the various Task Forces.
Changes already approved for the next revision:
· Changes to 9.3.1 Wattmeter-voltmeter-ammeter method from Mark Perkins’ PCS TF for Revision of C57.12.90. Final survey approved in Nov 2015 in both the TF and PCS. The following text is to be added just prior to Figure 18 for three-phase transformers: An alternate method for either single phase or three phase transformers is to provide capacitive compensation for the transformer impedance at the terminals of the transformer so that the AC source need only supply the real power for the test. Figure 18 shows the apparatus and connections for a single phase transformer for this alternate method and the method can also be used in a three phase configuration. In this case, the wattmeter will measure the real power of the transformer under test plus the power of the capacitors, which will be very small compared to the power in the transformer. The load loss in the transformer is determined by subtracting the loss in the capacitors from the measured loss. For modern oil film capacitors, a loss of 0.2 watts per actual kVAR may be used unless a specific capacitor bank loss is known. This method requires a separate CT or set of CTs at the transformer for setting the current and measuring the transformer impedance. The advantage of this alternate method is that the phase angle between the voltage and current at the wattmeter is low (closer to zero degrees) due to the capacitor compensation, so any phase angle errors in the loss measurement circuit are much less significant.
· Add in subclause 10.3.1 and 10.3.1.1 Lightning Impulse, the following words in red; by Pierre Riffon’s WG Revision to Impulse Test in Dielectric Test Subcommittee. Submitted on 11/4/2016. These subjects have been surveyed within the Dielectric Tests SC and within the TF. The 4th survey got a 100% approval rate.
Page 8 of 15 Annex L
10.3.1 Impulse tests shall be made without excitation. The impulse waveshape parameters such as peak voltage, front time and tail time are determined on the test voltage curve which is obtained after having processed the recorded curve using the test voltage function method, as defined in IEEE Std. 4.
10.3.1.1 Full-wave test The test wave rises to crest in 1.2 µs and decays to half of crest value in 50 µs from the virtual time zero. The crest value shall be in accordance with the assigned basic impulse insulation level (BIL), subject to a tolerance of ± 3%; and no flashover of the bushing or test gap shall occur. The tolerance on virtual front time should be ± 30%, and the tolerance on time to half of crest should be ± 20%. However, as a practical matter, once the manufacturer has proven that they have test equipment limitations, the following shall be considered: a) If the standard impulse shape cannot reasonably be obtained because of low winding inductance or high capacitance to earth and the resulting impulse shape is oscillatory so that the relative overshoot magnitude exceeds 5 % then the front time may be increased to reduce the overshoot amplitude. In all cases, the front time shall not exceed 2.5 µs regardless of the overshoot amplitude. Note 1: The overshoot can be reduced by increasing the front resistor value of the impulse generator. The use of low inductance connections between the impulse generator and the tested transformer are also recommended.
· New wording in subclause 10.3.1.3 Chopped-wave test, approved by the TF and SC following the Louisville meeting in Fall 2017. 10.3.1.3 Chopped-wave test A chopped wave is inherently a full lightning impulse wave, except that the crest value shall be at the required level and the voltage wave shall be chopped at or after the required time to flashover (time to chopping) but not later than 6 μs after virtual origin. The virtual front time of the chopped wave may be different than the virtual front during a full-wave test because of the presence of the chopping gap. Nevertheless, the tolerance on the virtual front time for the chopped-wave test should remain as defined for full-wave test. The gap or other equivalent chopping device shall be located as close as possible to the terminals of the transformer without disrupting its electrical field distribution. The distance between the chopping device and the test object shall not exceed a lead length greater than the total height of the transformer (tank + bushing). The impedance between the tested terminal and the grounded end of the chopping device shall be limited to that of the necessary leads. The voltage zero following the instant of chopping should occur within 1 μs. However, for some winding and transformer designs (particularly low-voltage windings of high stray capacitance, layer windings, high capacitance windings, UHV transformers requiring large clearances, etc.), the circuit response after chopping may not be oscillatory it may be overdamped or may collapse to zero with a lower frequency (slower voltage collapse). For such cases, the time interval to the first voltage zero after the instant of chopping may be significantly greater than 1 μs and this deviation shall be accepted if the chopping gap is located as described above. In order to have a common procedure for the determination of the steepness of voltage collapse, the steepness of the voltage collapse shall be the time interval between the instant of the voltage chopping to the instant where the applied voltage is 20% of the voltage level at instant of chopping. This time interval should be equal to or less than 0.8 µs. Only for cases…(this paragraph and the last paragraph remain as they are in the 2015 edition, including the three NOTES)…"
· Add the following text in red to subclause 10.8.2 Test Procedure (for Induced Test). This work was done in Bill Griesacker’s (formerly Bertrand Poulin) Task Force. The work started in 2015 and after
Page 9 of 15 Annex L
several surveys was approved by the TF and SC in October 2018. It stipulates a limit of overpressure applied inside a transformer tank during induced voltage test. 10.8.2 Test procedure The voltage shall first be raised to the 1 h level and held for a minimum of 1 min or until a stable partial discharge level is obtained to verify that there are no partial discharge problems. The level of partial discharges shall be recorded just before raising the voltage to the enhancement level. The voltage shall then be raised to the enhancement level and held for 7200 cycles. The voltage shall then be reduced directly to the 1 h level and held for 1 h.
During this 1 h period, partial discharge measurements shall be made at 5 min intervals. Partial discharge acceptance criteria shall be based on each line terminal rated 69 kV and above. These measurements shall be made in accordance with 10.9.
The pressure inside the transformer tank during induced test shall not be increased by artificial means for the purpose of reducing the PD level. The liquid level and pressure inside of the transformer tank and/or conservator tank shall be configured such that oil head pressure during the induced test does not exceed the pressure under usual service conditions. Any exceptions that increase tank pressure by more than 3.5 kPa (0.5 psi) over normal operating pressure, such as the use of an elevated test facility conservator tank, requires customer approval prior to test. A note shall be added to the certified test report confirming this approval. Note: Increasing the pressure for diagnostic purposes, such as to identify and possibly reduce suspected bubbles in the liquid, may be done as a remedial step to diagnose a source of high PD. To be considered valid, the test shall be repeated with no added pressure as stated above.
· Other revisions to subclauses 10.2 to 10.4 from Pierre Riffon’s TF for revision of impulse tests. Ongoing work continues. This text was approved by the Task Force and SC in Spring 2019. Add the following text in red to subclause 10.3.2.1 Connection of tertiary bushings during impulse test 10.3.2.1 Terminals not being tested
Neutral terminals shall be solidly grounded. Line terminals, including those of autotransformers and regulating transformers, shall be either solidly grounded or grounded through a resistor with an ohmic value not in excess of the values given in Table 3.
Tertiary winding terminals shall be considered as line terminals. When buried stabilizing winding terminals which are buried and have been temporarily brought out of the tank for testing purposes only, they shall be kept connected in the same way condition as they will be in service during impulse tests (grounded or in open circuit) as foreseen for service. When a stabilizing winding terminal is brought out of the tank for the purpose of grounding purposes the winding, this terminal shall be grounded during the entire impulse tests sequence. When stabilizing winding terminals are brought out of the tank for the purpose of grounding the winding and for closing the delta, these terminals shall be grounded and connected as required intended for use in service for during the impulse tests sequence. The rest of the clause remains as is. This text was approved by the Task Force and SC in Spring 2019. Add the following text in red to subclause 10.2.4 Tap positions during Switching Impulse Test
Page 10 of 15 Annex L
10.2.4 Tap connection The choice of the tap connection shall follow the following rules: · The tap position shall be selected in order to induce, as close as possible (preferably within ±3%), the rated switching impulse withstand voltage value on the LV winding terminal; · If the LV winding has no rated switching impulse level, the tap position shall be selected in order to induce, as close as possible (preferably within ±3%), 83% of the LV winding rated BIL value on LV winding terminal. It should be noted that for some cases, the LV winding may receive a voltage which is less than its rated switching impulse level or 83% of its rated BIL and this shall be accepted. It should be also noted that for some other cases, the LV winding may receive a voltage which is higher than its rated switching impulse level or 83%of its rated BIL, this shall be accepted and the transformer shall be designed for it. For transformers having a preventive autotransformer, the tap changer shall be in a bridging positing if this operational mode is permitted for continuous operation." pending work · Possible future addition of a new clause for a Load Tap Changer Performance Test, from Hakan Sahid PCS TF for Revision of C57.12.90. This TF also is considering: a) to add a new clause 4.5 in General Section that a transformer be tested with the same insulation liquid that it will use in service. For example, a unit to be filled with ester liquid should (or shall?) not be tested with mineral oil in the factory. Or this requirement may be put into C57.12.00 Clause 8.1 General Testing. This work was to be forwarded after Fall 2018 to Standards SC. However, I am not sure I saw it on that SC’s agenda. b) Load Tap Changer performance 8.7 voltage test and 9.6 current test. Text seems to have been approved in Fall 2018, and moved up to the Perf Char SC. Spring 2019 this work was not on TF or SC agendas, so the result is not clear. Was it surveyed in TF and SC? c) Addition in 5.4.1 new wording for winding resistance test requirement on wye connected transformers with neutral bushing brought out. Fall 2018 meeting minutes not clear as to disposition of this issue. Spring 2019 this work was not on TF or SC agendas. Was it surveyed in TF and SC? d) Number of short circuit tests under clause 12.3.4. Spring 2019 this work is ongoing. e) Altitude correction under clause 11.4.2. Spring 2019 this work was not on TF or SC agendas. Note that clause 11 is out of scope of PCS. f) OLTC continuity tests. Spring 2019 this work was not on TF or SC agendas. g) Request to change frequency bandwith in 7.1.2. Spring 2019 New Business.
· Other possible revisions to subclauses 10.5 to 10.10 from Bill Griesacker’s TF (formerly Bertrand Poulin) for revision of low frequency tests. Ongoing work continues. • A TF has been formed to look at reducing the limit for PD level Failure Detection in 10.8.5, along with the PD test procedure. In Spring 2019 the TF approved lowering from 500 to 250 pC limit, and from 150 to 50 pC increase, both during the one-hour test. It will be moved to the SC. • Text for venting bushings during PD test, Fall 2018. Dave Geibel Study Group
Page 11 of 15 Annex L
“If partial discharge is observed during the induced testing of the transformer and appears to be generated within an OIP bushing(s), it is permissible to “vent” the bushing(s) to atmosphere using the bushing manufacturer’s instructions to allow for the dissipation of gas bubbles in the oil. Gas bubbles sometimes form following a temperature rise test during cool down or may be present for other reasons. Reestablishment of the bushing gas space blanket and resealing of the bushing must also be performed in accordance with the bushing manufacturer’s instructions following completion of the induced test.” • Clarification of measuring voltage during low frequency tests – Bertrand Poulin • Class I transformer PD test revision to the test procedure – Don Ayers · Possible additions from Phil Hopkinson to detect improper core grounding in 10.7.7 for Special Induced-Voltage partial discharge Test for distribution and class I power transformers with a wound core, L-H winding construction and HV >15 kV. PD is to be measured as apparent charge in pico- coulombs (pC). One reading shall be made at the end of each interval. Minimum test duration and application of voltage: 1. Voltage shall be raised to 100% of rated volts for 30 seconds and PD shall be measured and recorded. 2. Voltage shall be raised to 110% of rated volts for 30 seconds and PD shall be measured and recorded. 3. Voltage shall be raised to 150% of rated volts, held for 1 minute and PD shall be measured and recorded. 4. Voltage shall be lowered to 140% of rated volts, held for 1 minute and PD shall be measured and recorded. 5. Voltage shall be lowered to 130% of rated volts, held for 1 minute and PD shall be measured and recorded. 6. Voltage shall be lowered to 120% of rated volts, held for 1 minute and PD shall be measured and recorded. 7. Voltage shall be lowered to 110% of rated volts, held for 10 minutes and PD shall be measured and recorded.

L.3.4 Task Force to create a PAR for Revision of C57.152, IEEE/PES Transformer Committee
The Task Force for revision of the C57.152 met on Monday, March 25th, 2019. The Chair, Marcos Ferreira called the Group to order at 9:30am and explained purpose and scope of the TF. There were 40 attendees and all automatically become members. The TF meeting was well attended. The Attendances were registered in a paper roster and listed at the end of this document.
The Agenda as proposed was approved.
Page 12 of 15 Annex L
The Chair presented the purpose of this task force to review the existing Title and Scope of current version for C57.152, in order to create a PAR. Therefore, a working group will be formed and approved by the Standards SC Officers to add a new revision.
The original Title, “IEEE Guide for Diagnostic Field Test of Fluid-Filled Power Transformers, Regulators, and Reactors”,
The original Scope, “This guide describes diagnostic field tests and measurements that are performed on fluid-filled power transformers and regulators. Whenever possible, shunt reactors are treated in a similar manner to transformers. The tests are presented systematically in categories depending on the subsystem of the unit being examined. A diagnostic chart is included as an aid to identifying the various subsystems. Additional information is provided regarding specialized test and measuring techniques.
Interpretive discussions are also included in several areas to provide additional insight on the particular test or to provide guidance on acceptance criteria. These discussions are based on the authors’ judgment of accepted practice. It should be noted that the results of several types of tests should be interpreted together to diagnose a problem. Manufacturers’ acceptance criteria and other standards in the IEEE C57™ series take precedence over the content of this guide.”
Brian Penny formulated a motion to approve the original title. Robert Thomson second it.
Discussion: Jerry Murphy informed that recent IEEE documents uses the terminology “Liquid Filled” instead of “Fluid-Filled”. Mario Locarno said that the fluid/liquid means excluding dry type transformers that many of test methods in the guide are well suited for. Susan McNelly pointed out that remove Fluid will significantly extend the work revise/update the document. Craig Stiegemeier, Don Platts, Robert Thomson and Jeff Murphy also participated in the discussion.
Susan McNelly formulated a motion to delete “fluid-filled” in the original title. Craig Stiegemeier second it. Discussion: similar to above Susan McNelly withdraw the motion, Craig second the withdraw
Craig Stiegemeier formulate a motion to a title with fluid-filled replaced by “liquid filled”. Seconded by Robert Thomson.
Vote: All vote in favor, except 1 abstain
Decided Title: IEEE Guide for Diagnostic Field Testing of Liquid Filled Power Transformers, Regulators, and Reactors.
Motion was proposed by John Harley and seconded by Robert Thompson to delete the three bold sentences in the scope below.

Vote: All in favor, but except 1 abstain
Motion was proposed by Bernard Kurth and seconded by Robert Thompson to delete the last sentence of the scope (in bold). Remaining part of Original Scope, “This guide describes diagnostic field tests and measurements that are performed on fluid-filled power transformers and regulators. Whenever possible, shunt reactors are treated in a similar manner to transformers. The tests are presented systematically in categories depending on the subsystem of the unit being examined. A diagnostic chart is included as an aid to identifying the various subsystems. Additional information is provided regarding specialized test and measuring techniques.
Manufacturers’ acceptance criteria and other standards in the IEEE C57™ series take precedence over the content of this guide.”
Vote: 22 in favor, 3 against, 1 abstain
The following text of the Scope was decided: This guide describes diagnostic field tests and measurements that are performed on liquid filled power transformers and regulators. Whenever possible, shunt reactors are treated in a similar manner to transformers. The tests are presented systematically in categories depending on the subsystem of the unit being examined. A diagnostic chart is included as an aid to identifying the various subsystems. Additional information is provided regarding specialized test and measuring techniques.
TF Chair, Marcos Ferreira, after reported the meeting minutes of his meeting took place on Monday, informed to the SC Standards that he will request to the group to initiate a PAR for a working group to do a revision of the IEEE Guide for Field Tests, C57.152. Therefore, Standards SC Chair approved the request and assigned Marcos Ferreira as a Chair for the new WG of C57.152.

The meeting was called to order at 9:30 am in the Capistrano Room at the Hilton Anaheim on Tuesday March 26, 2019. In the Chair’s absence, Dan Mulkey filled in. George Payerle served as secretary. Dan presented an agenda. Kent Miller moved to approve it. Tom Dauzat seconded. The minutes were approved unanimously again with Kent Miller making the motion and Tom Dauzat seconding.
Introductions were made. The Chair noted that the Par for this group was approved. It now expires December 23, 2023.
At the previous meeting, Israel Barrientos and Jeremy VanHorn took on the task of revising Table 6 to harmonize the metric and English values. Israel presented their suggestion for the new table of minimum tank thicknesses. Tom Dauzat mentioned that there is testing going on in 12.32 that is relevant here as it will overlap with this standard.
Dan explained that for normal corrosive areas, whatever your substrate is, it has to meet or beat the weight loss criteria of 409 stainless steel. If you are in a heavily corrosive area, then your bare substrate has to meet or beat 304 stainless steel.
C57.12.40 and C57.12.44 call for CU bearing steel. There is probably a minimum thickness that will have less weight loss than 409 or 304. There will probably be 2 different thicknesses. Currently GE is running tests to make that determination. Tom Dauzat stated that the testing will take 6 to 10 months. He expects to have results for the spring 2020 meeting. Tom suggested that another manufacturer do the same testing. We will proceed with the decimal change in table 6 for now and await the test results. Dan noted that the standard needs to go to ballot by fall of 2022.
Brian Klaponski noted that in C57.12.40 we got a negative comment by a corrosion expert that has kicked off a good effort in adding significant helpful information to several standards.
Table 2 was discussed. The title should be changed from “Primary Insulation Level” to “Winding Insulation Level”. Additions should be made for insulation levels above 600 volts.
The figure under 7.1 needs to have a figure number. The tables under 7.1 need to have numbers. It was noted that IEEE would want two separate numbers in this case, Table 3 for rectangular transformers and table 4 for round transformers. These new designations will of course change the figure and table numbers below that point. Also, add 5000 kVA under 150 kV BIL. That line will also need dimensions. Brian Klaponski will help with table revision. There is a figure for rectangular transformers. Should there be a figure for round transformers?
Page 3 of 11 Annex M 3/28/2018
There was a discussion as to whether table 2 should include winding voltages above 600 volts. It was determined that the BIL of winding voltages above 600 volts should be in table 2. Below 600 v the BIL should be 30 and these numbers should be either in another table or added to table 2. If anyone wants to add voltages to table 2, they should sent them to George or Giuseppe. Also send any desired changes to table 3 impedance voltages to George or Giuseppe.
Also, we should change the title of table 2 to ‘Winding Insulation Level”. And make other changes within the table to match the table in C57.12.00.
We need to amend Table 6 minimum thickness to take into account the minimum thicknesses to roll round tanks.
Table 3, impedance, members should also send any changes or additions. We will also have to change the table title as well. Carlos Gaytan said to see the impedance table in 12.34 3ph pads and copy data from there. We will need to add a column.
Will Elliott then presented an excellent corrosion presentation that he and Tom Dauzat created. Liz Sullivan said that she has data on corrosion that she can supply. Tom Dauzat suggested that each utility find 5 vaults and record potential differences in them. A methodology for this would have to be developed.
After the presentation Brian Klaponski suggested that a task force be created at the subcommittee level to continue work on this and make an appendix that will be useful to many different working groups.
The meeting was adjourned at 10:52 AM. The next meeting will be in Columbus, OH on October 29, 2019.

4) The Chair announced that due to late submittal of the PAR, this is not officially a Working Group meeting.
5) The Chair briefly noted that the PAR was submitted late and was not approved prior to this meeting.
6) The Chair opened up the meeting for discussion on topics to be addressed in the next revision of C57.12.40 and the following suggestions were made and discussed:
a. It was discussed that the formation of a Task Force on Corrosion and Cathodic Protection should be brought up at the SC meeting on March 27th as that discussion and findings would be applicable to both this WG and C57.12.24. This topic is seen as potentially included in the next revision of both standards, but more likely the revision after. This is a potential continuation from the TF created at the previous meeting in Jacksonville, FL. b. Taking up a discussion on the standardization of throat and tank sizing to include potential figures in the standard. c. Further improvement on Bushing Connection standardization and documentation within the standard. d. It was also discussed that we should visit the addition of the primary switch location in the next revision of the standard. Among items applicable to this topic are allowing user choices of locating the switch in the tank, separate from the tank, and locating the switch in its own tank; the standard should provide guidance for all three. A concern was raised that the WG should focus on maintaining the safety aspect of the previous revisions when considering how to address these potential additions as work practice vs. equipment safety. e. 7) The meeting was adjourned at 11:39 AM with the next meeting set for Columbus, OH on October, 29, 2019.

Questions/Comments:
There was a discussion about a conference call presentation that was done but not everyone was able to participate. There was interest in having time set aside at this meeting for the presentation but Gary didn’t want to take away from WG activities. There was a suggestion to either arrange for a Thursday tutorial at a future meeting or arrange for a Thurs/Friday time slot.
N.1 Old Business Nothing needed to be revisited
N.2 New Business The chair mentioned that Don Platts raised an issue during the AdCom session about the use of “Liquid Immersed Transformers”. It technically is not an accurate description and he used a photograph of a transformer that was dropped into a river to show what a “Liquid Immersed Transformer” looks like. This issue will be raised to the Standards Committee.
A motion was made by Brian Klaponski based on discussions coming out of the PC57.12.24 and PC57.12.40 meetings. The motion requested that a TF to be approved by this SC to continue the ongoing activities on corrosion during the Tuesday meeting schedule. The motion was presented on the overhead for the group to consider:
“I motion that this Subcommittee establish a new Task Force regarding corrosion prevention (including cathodic protection) associated with Network transformers, Submersible Transformers, and Network Protectors. The objective is to create a Guide or a Standard or an Annex on corrosion prevention for the equipment in our SC standards. Part of my motion is to allow this new TF to recommend whether the publication resulting from their work should be a Guide, Annex, or a Standard. Also as part of my motion is that in creating this TF we recognize that this TF is not a short term TF so the TF will exist for several years. To facilitate this work, this SC will request an ongoing slot for this TF to meet on Tuesday afternoons during our semiannual meetings starting in the Fall of 2019."
During the discussions Fred Friend from AEP offered to look into having his company make/sponsor a presentation during the Fall 2019 meeting in Columbus. Brian also noted that input from the other working groups, 12.24, 12.40, and 12.44 on the exact title for the new task force would be welcomed.
The motion was seconded by David Blew and was passed without opposition.
It was already determined that Will Elliott would Chair and Justin Minikel volunteered as Secretary. Additional volunteers were Jennifer Corvigno, Brad Kittrell and Jason Atard.
The meeting was adjourned at 11:37. Tom Dauzat made the motion and Jim Dorsten seconded. The next meeting will take place on October 30, 2019 in Columbus, Ohio.
Respectfully submitted,
