Membership Code CM – Committee Member CM – LM – Committee Member – IEEE Life Member AP – Active Participant II – Interested Individual SP – Spouse / Companion GT – Guest 1.0 Chair’s Report IEEE PES Transformers Committee Spring 2011, San Diego Meeting

1.1 Transformers Committee Highlights

1.1.1 Subcommittee Chair reappointed for the calendar year 2011 Meetings Planning Gregory Anderson Standards William Bartley Dielectric Test Loren Wagenaar Distribution Transformers Stephen Shull Dry-Type Transformers Charles Johnson HVDC Richard Dudley Insulating Fluids Susan McNelly Insulation Life Bruce Forsyth Performance Characteristics Stephen Antosz Power Transformers Tom Lundquist Underground Transformers & Network Protectors Carl Niemann

1.1.2 Consistent with the Transformers Committee’s O&P manual, Damir Novosel, Chair, PES Technical Council was notified of the Transformers Committee, Subcommittee reappointments for the calendar year 2011.

1.1.3 The Audible Sound and Vibration Subcommittee was disbanded and the one Task Force (Task Force on revisions to Clause 13 of C57.12.90) was moved to the Performance Characteristics Subcommittee. The Sound Measurement Guide C57.151 is on hold, while waiting for the revisions to Clause 13 of C57.12.90 to be done.

1.1.4 I have confirmed that our current “approved” Transformers Committees Operation & Procedure Manual (O&P) and the Working Group Practices & Procedures Manual(P&P), documents have and 5 year life without requiring revision. However I think it’s important that we move forward with establishing a plan for the revision process. Therefore, I am establishing a Task Force for the “continuous revision” of the Transformers Committee’s O&P and P&P Manual.

The basic Organization and Details are as follows. . . .

Task Force Purpose The purpose of this Task Force is to maintain and update the Transformers Committee Operation and Procedures Manual and Working Group Practices and Procedures Manual.

Task Force Chair I have asked and Peter Balma has accepted the responsibility to Chair this Task Force. This Task Force will report to, and fall under the direction of the Transformers Committees Vice Chair.

Task Force Membership Task Force members will consist of the following. . . . Permanent Members Committee Chair Committee Vice Chair Committee Secretary Standards Coordinator Committee Treasurer Immediate Past Chair Members at large Members at large should come from the Administrative Subcommittee and past Chairs of the Transformers Committee (at O&P & P&P Task Force Committee Chairs’ discretion)

Task Force Meeting Schedule The Task Force will be assigned a meeting slot at each of our future Transformers Committee meetings. I will ask Greg to assign a specific meeting time and location at each one of our meetings (to be coordinated with the O&P & P&P Task Force Committee Chair)

1.1.5 A request has been received from Wayne Beaty, Editor, McGraw-Hill Publications to update the Transformer section (section 10.1) of the Standard Handbook for Electrical Engineers, 16th. I discussed this issue with Tom Prevost and we both agreed that it would be inappropriate for our group to edit and or revise Technical information from published authors. The appropriate direction would be for McGraw-Hill to make contact with the original authors and request an technical update.

1.1.6 Consistent with the PES Technical Council requirements the following information for the 2011 Transformers Committee Officers and Committee meetings was sent to Damir Novosel, Chair, PES Technical Council.

1.2.3 Technical Council Meeting Highlights Technical Council Meeting, Thursday, January 13, 2011, 8:00am – 11:00am, Atlanta, Ga Discussion Summary: There was a motion made to disband the Policy Development Committee and to handle all policy issues on a case by case basis by establishing a Adhoc Committee. This action will implement immediately following the 2011 General Meeting. The motion passed unanimously. Jeff Nelson reminded all Technical Committee Chairs that they need to submit their ADCOM Member rosters for the calendar year 2011. Also requested was a list of future meetings of the Transformers Committee. This is an ACTION ITEM Completed

1.2.4 Damir reviewed the 2011 and 2012 PES Goals and Objectives presented by Al Rotz. See Appendix C (In Chairs Report for slides)

1.2.5 General Discussion The 2011 General meeting will basically be structured similar to the 2010 Minneapolis General Meeting. No large or noteworthy changes.

Michael Lindsey, IEEE SA Legal Council could not be in attendance because of weather. He delivered a great program in Minneapolis on The Responsibility of attendees - members not promoting and pushing their personal or corporate agenda’s.

Matt Ceglia discussed the IEEE SA requirement for the O&P Manual and P&P Manual. AUDCOM approval requires that the O&P and P&P address the “Standards Development” process and all Technical Committee organization and procedures be removed. This new format requires the approval of AUDCOM. Our own Peter Balma in a member and Chair of AUDCOM. A separate document for both the O&P and P&P is required to cover the Technical Committee’s organization and procedures. These manuals only require the approval of the Technical Committees Administrative Subcommittee.

See Attachment A (In Chairs Report) for the Technical Council Meeting Agenda

1.2.6 O & P Manual Committee Meeting Highlights O & P Manual Committee Meeting, Thursday, January 13, 2011, Atlanta, GA

Discussion Summary: 1) AudCom realizes that significant time and effort was put into work on the P&Ps for the Power & Energy Sponsors and that AudCom, in changing course of direction midway through the review process, has added to the time necessary (not to mention the frustration) for submitting procedures which will be accepted by AudCom and the Standards Board.

2) The following changes have occurred in AudCom requirements and/or expectations for P&P submittals since the PES Transformer Committee P&Ps were accepted:

a) AudCom now requires separate Working Group P&Ps and requires all material pertaining to these WG procedures to be removed from the Sponsor procedures. (This was taken into account for the O&Ps that we approved in July and and were subsequently submitted to AudCom for approval)

b) Any material pertaining to subjects outside of Standards Development should be removed from the document. The rationale for this change is, AudCom and the SASB do not want to be on record as endorsing –sponsor practices that are outside of the scope of standards development.

c) AudCom would prefer the format and numbering of sections to match the AudCom baseline as much as possible.

3) Using PE/SWG as a model, it appears necessary to include subcommittee scopes in the Sponsor P&P document.

4) AudCom will meet on 6 December 2010. AudCom has told me they will discuss the status of all Power and Energy P&Ps and give clear direction on the expectations going forward. Matt and Lisa will attend the meeting prepared with a list of clarifications needed and make sure guidance is given for each point. I am also making plans to be in attendance at the AudCom meeting. AudCom will also vote on granting PES an extension for all of our P&P documents, which shouldn’t be an issue.

5) Following the meeting, AudCom's position will be put in writing for PES and I will communicate this information to you. Then we can develop a plan of action going forward. The AudCom Chair said he looks forward to resolving the confusion and moving forward so that PES can continue with its business of standards development. See AudCom’s meeting minutes below . . . .

1.2.7 The Wednesday CIGRE meeting was cancelled due to the Atlanta weather. The International CIDRE representatives could not get in. The Luncheon was still held but no formal meeting.

Jodi Haasz updated the Technical Council members on the IEC development work. She specifically pointed out the very recent IEC approval of our own C57.15 Step Voltage Regulator Standard. The working group is Chaired by Craig Calopy

1) It was noted that, at the IEC General Meeting, Jim Matthews, the incoming Chair of the IEC Standardization Management Board (SMB) is interested in leveraging IEC's agreement with IEEE

2) There are currently 25 documents adopted under the agreement, two of which came from PES - One from SWG, the other from TR

3)There are currently 18 projects undergoing joint development and maintenance - of these 18 projects, 13 are from PES (one project is forthcoming). The breakdown of these projects are as follows:

3 from SWG (Two are actually joint, one is a maintenance project) 1 from ED&PG (which is actually a maintenance project under the agreement) 6 from NPEC (three of which should obtain final approval by June 2011 1 from TR We are awaiting for IEC approval on one from PSR COMTRADE (PSR) is undergoing a revision via the maintenance agreement with IEC.

4) A guidance brochure has been drafted by both IEEE (with volunteer input) and IEC to explain all procedures for the IEC/IEEE Dual Logo Agreement. This brochure should be published by mid-2011. It was pointed out that the PES Awards Committee is basically falling apart (their words) due to very poor, indecisive leadership. A new Chair is being considered. The PES is also requesting that all the Technical Committees review their Committee for opportunities for PES awards. Emphasis should be placed on outstanding work, significant accomplishments, special recognition, and other reasons for recognition.

The Transformers Committee currently has three general categories of participation in our activities. These are: Interested Individual, Active Participant, and Committee Member. Anyone can join our 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. 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 minimum of three WG or SC chairmanships. Detail of the application requirements and approval process by the Administrative Subcommittee is outlined in our O&P manual.

The following table contains a recent count of the participants grouped by the three general categories. October 2010 April 2011 Interested Individual 843 997 Interested Individual - IEEE Life Member * 6 2 Total Interested Individuals 845 999

Active Participant 227 230 Active Participant - IEEE Life Member * 7 5 Total Active Participants 234 235

During the week of April 4, I sent email messages to 80 Committee Members who had not signed into any of the past 4 General Session meetings. Several members responded that they should be removed from the list. Many others feel that they do not get any value from the Thursday meeting, and since they are paying their own way to the meeting, they choose not to stay for Thursday. So this is an old ongoing topic of discussion. If we don’t resolve this, we will have a problem getting a quorum if we need to take a vote at a Thursday General Session.

There are 11 new member applications to be reviewed. After the review of member’s attendance at the Thursday meetings, I checked and found that about ½ of the new applications have not attended. This is not a criterion to be met by new applicants. It is a requirement after they become a committee member. We agreed to note that information for each applicant, but not to factor that into the decision to approve the application. Dudley pointed out that none of the applicants are users. This led to continuing discussion of the issues related to getting more user participation in our meetings. Greg Anderson reported that we have 16 new users who took advantage of the promotion to allow new participants to attend with a free registration.

New Member Applications Eleven new applications for Committee Membership have been received since our previous meeting in Toronto, ON. They were reviewed for approval at the San Diego, CA meeting. Details of the membership applications and sponsors are listed in the following table.

Nine of these applications were reviewed and approved at the Spring 2011 Administrative Subcommittee meeting. Two were held for clarifications of their applications

Mr Brender is not listed as a member of any WG in the AMS system. Mr. Locarno is listed as a member of just 1 WG in the AMS system.

The Committee welcomes and encourages active participants to become Members of the Committee. Requirements and application forms can be found in the Organization and Procedures (O&P) Manual, accessible on the Committee website. Subcommittee Chairs are encouraged to recommend new members, and to communicate the process of attaining membership through active participation and contribution in Committee work at the WG and SC level. WG and SC Chairs are reminded also that signing an application sponsoring a new member signifies their sponsorship that the applicant has met the requirement of membership and active participation for at least one year in the WG or SC they Chair. New member applications may be submitted to the Committee Secretary’s attention at any time. Applications will be collected for review and approval in batches at each Administrative Subcommittee meeting. For an application to be reviewed at the next meeting, the application will need to be received by the Committee Secretary a minimum of one week prior to the start of the that meeting.

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. Our 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.

A similar main committee roster has also been developed to track attendance for the Main Committee meeting on Thursdays. The data will be used to update participant’s membership profile.

Meeting Minutes The minutes of the Toronto, ON Spring, 2010 Transformers Committee meeting were posted to the committee website on March 5, 2011.

Subcommittee Chairs are requested to submit their SC Minutes from the San Diego, CA meeting by June 15, 2011. The minutes should be submitted via e-mail to the Committee Secretary at [[email protected]], with a copy to Susan McNelly [[email protected]] for posting on the Committee website.

S-11 AdSubcom_Minutes.doc Page 8 of 13 The submittal should be formatted in Word 2007 (or earlier versions) and should be formatted similar to this report, and as shown in the recent assembled Minutes. The numbering for your report should match the numbering as indicated in the Main Committee Meeting Agenda. Please indicate total attendance count for each Subcommittee, Working Group, and Task Force meeting in your Minutes. Please do not send a copy of the attendance listing for this attendance count.

If a SC Vice-Chair, Secretary, or other SC member is preparing the SC Minutes, please advise them of these details regarding the Minutes submittals. Please do all you can to get the minutes in as soon as possible. Collecting the minutes from each subcommittee is the most difficult and time consuming part of this job. Your full corporation and support in this matter is greatly appreciated.

3.6Treasurer Report – Greg Anderson Greg Anderson passed around a recent account ledger showing the various funds deposited and expenses for the committee business, and a balance sheet. He stated that overall the committee funds are in good shape. Greg will be submitting the filings required by IEEE. It is overdue.

3.9Standards Report – B. Bartley Bill Bartley discussed the highlights of the draft report of standards activities since the October, 2010 Meeting (Toronto, ON).

Matt Ceglia will no longer be the program manager for Transformers Committee activities. Erin Spiewak is temporarily assigned to handle standards liaison for all PES activities. She is not our new program manager. Contact info: [email protected] 732-465-7806.

Major change in IEEE Ballot Procedure has been proposed. Standards Board of Governors to vote. Reaffirmation and Stabilization options will be eliminated. Starting in 2012 every standard will have a 10 year life, not 5. All of them must be revised at least every 10 years.

A key concern is the IEEE risk that develops when comments are not addressed in a reaffirmation ballot. Or the ballot resolution group simply dismisses comments on technical flaws by stating “reaffirmation doesn’t allow changes”.

S-11 AdSubcom_Minutes.doc Page 10 of 13 ANSI still has a 5 year limit on standards. May be able to satisfy ANSI with a 5 year extension. Some of our documents are also ANSI standards, so they may require extra efforts.

Subcommittee Chairs asked to review Standards Database to ensure that the information provided is correct.

Presently have approximately 90 documents, and 43 active PARS. Many (23) documents will expire at the end of the year, if we do not act.

Further details of the standards activities are listed in the Standards Report and it is included in the Appendix C - Transformer Standards Development Status and Transformer Committee Organizational Chart. 2 new standards have been approved. No document revisions have been approved.

The Standards Board submission dates for this year are: DEADLINES for upcoming NESCOM and REVCOM Submissions: June Meeting May 6, 2011 September Meeting July 29, 2011 December Meeting October 17, 2011

3.10 New Business

Continuous Review of O&P and the P&P Manual revisions Task Force Chair Peter Balma Operations and Procedures Manual approved in 2009, and published. Valid until 2014 Policies and Procedures for Working Groups approved and published. Valid until 2015

Any procedures listed in the documents must be followed. The documents must contain only information related to developing standards Special publications Special Tutorial type booklets, etc. WG or TF can publish a technical paper. Follow the normal PES paper process. But the Complete Transformers Committee must approve it, if there is a reference to it as a Transformers Committee paper.

Historical information We now have minutes back to 1981. If we can find any older minutes we will gladly accept any of them, or old technical papers.

We will publish an update of our standards documents on CD, by the Boston meeting. All active documents will be published. Motion Shull. The CD should include the latest published standards available as of the date it is submitted for publication. Motion carried unanimously. There was no additional new business

IEEE Power & Energy Society Author’s Kit (Part 8 last revised December 2005) Part 8: Reviewer and Editor Guidelines

Transactions Papers The Editors and Editors-in-Chief must make decisions on which works submitted to our journals are printed and become part of our archived literature. We reiterate that the reviewers are ultimately responsible to the Authors and the invisible college of our readership for ensuring that the content of the Transactions represents the evolution and progress of our discipline. We need your assistance to accomplish this task. The following guidelines are offered in the hope that they will aid the reviewers toward the composition of what we hope to be outstanding technical journals.

Content of IEEE Power & Energy Society Transactions The purpose of the Transactions is to disseminate technical information that signifies new and evolving thoughts. We are among the best in the business, but we do have competition. If we are to maintain our place on library, university and corporate bookshelves, the content of our journals should be refreshingly new, different, novel, and, at times, even controversial. Because of the intellectual content of the printed articles, they should represent the evolution of the state of the art. Thus, our journals will be of long-term value. These attributes are somewhat subjective, but their definitions need no further debate. However, it is important to agree that accepted articles should be more than being correct or accurate. A very ordinary piece of engineering can be correct but may not necessarily be of archival importance, for it might just be a new twist on an old idea. The articles in our Transactions must be of unquestionable value to the reader. In turn, this means that the reader should not be able to find the equivalent content in another journal or conference proceedings of our Society, or of any other organization. In essence, our criterion should match what the publisher of any high quality journal wants to provide — thought or information which is unique and cannot be found in another place in this form, or as a variant of it. The above requirements suggest the following criteria for papers that should and should not appear in the Transactions. Papers of archival value should: 1. Present new methods of analysis or experimentation. 2. Present a new process, design, or technology. 3. Discuss and provide fresh thoughts on the effects of evolving public and environmental policies on the technologies we address and operate. 4. Be written in clear and understandable language. 5. Be of interest to the reader of our journals. 6. Be of long-term value for the profession because of the above attributes.

Such papers are not those that: 1. Plagiarize or regurgitate old and well-proven thoughts. 2. Represent a minor variant of an old thought or analysis. 3. Are written exposing the same or similar ideas in other journals or proceedings. 4. Have copied others’ ideas without proper acknowledgment. 5. Are poorly written, or written in an obscure manner.

What the Editor-in-Chief Needs in a Review The Editor-in-Chief must make decisions on what papers are to be printed in the Journal. Our page budget is limited and can include only about one third of the papers that are currently being submitted. Reviewers are urged to seriously consider the criteria outlined above when reviewing a paper. If a paper satisfies all the above criteria, it should be accepted. If corrections of minor errors such as undersized captions, font size, and misspellings would make the paper of longer-term value, it should be accepted after the corrections. Otherwise, it should be rejected.

Timeliness The journals of the Power & Energy Society have adopted a goal of 90% of paper decisions within 90 days of submission. This does not appear unreasonable as PES uses a web based system that allows papers submitted to be in the hands of reviewers within only a few days of actual submission. If the authors of submitted papers can’t have a decision within a reasonable time they will take their work to one of our competitor journals. Besides, professional courtesy demands that we review the papers in a reasonable time — just as we expect our papers to be reviewed by others quickly. Please do review the paper right away. Don’t put it off, or put the paper in a pile of stuff ‘to be done’.

Specific Instructions to Access Papers Reviews are carried out through Manuscript Central, a web based system that is reached over the Internet using a browser. The web sites are http://tec-ieee.manuscriptcentral.com, http://tpwrs- ieee.manuscriptcentral.com and http://tpwrd-ieee.manuscriptcentral.com. All who interact with these web sites have a user account. This includes all authors. The Editor-in-Chief or headquarters staff appoints reviewers for fixed or indefinite terms, and once assigned, a reviewer can access that paper on the web site. The paper can be either downloaded for printing or read directly in your browser, but you will need some mechanism for reading documents in ‘Page Description Format’ (PDF) files. Most personal computer systems have a reader and if yours doesn’t, you can download a free reader from the Adobe web site. The review consists of two parts: a numerical rating which is based on several multiple choice elements implemented as ‘radio buttons’ on the web site. This numerical rating is important, but more important is the subjective rating of the reviewer in the form of a few paragraphs of text. In writing such review comments about the paper the reviewer should ponder the above criteria. Does the paper present a new method for design, analysis or experimentation? Is that technique good? (Is it useful?) Is it interesting? Does it have long-term value for the profession? If the answers to those questions are not all ‘yes’, the paper will probably be turned down. The reviewer should address each of these questions in the written analysis of the paper. Here are two situations in which a paper should be returned to the author for revisions: 1. If the paper is not written in clear and understandable language. In this case the authors should have the opportunity and the obligation to make the paper understandable. Returning a paper under these circumstances does not imply that the paper will eventually be accepted.

2. If a paper is otherwise acceptable but has minor issues such as figures being too small to be read, awkward syntax, etc. The author should be asked to fix these defects. In such situations the paper may not need to be reviewed again.

Returning the paper to an author with a request for revisions is not appropriate if there are any major problems such as lack of experimental verification, explanation of a major point, etc. In other words, if the contents and the theme of a paper do not meet the above criteria of archival value, revisions to a paper would not make it acceptable. Such shortcomings are grounds for rejection. If a paper is rejected, Editors are requested to provide the following directions to the authors: 1. If the paper does not fit within the scope of our Transactions it should not be resubmitted as a revision. 2. If major changes are required the paper may be submitted considering the reviewers’ comments. It must not be resubmitted with a few cosmetic changes. In its revised form it should meet the criteria for a Transactions paper.

If the contribution is considered to be only incremental over existing published literature the paper should NOT be revised and resubmitted. However a new paper based on additional work done by the authors will be considered. It is important that reviewers indicate in their review not only what is wrong with a paper, but also what is right. The reviewer of a good paper should indicate why it should be accepted, just as the reviewer of a bad paper should indicate why it should be rejected. We, the Editors and Editors-in-Chief are very appreciative of the time and effort put into preparation of papers for the Transactions. We wish to ensure that each work submitted to us gets a fair, complete and timely review. We are also grateful to the reviewers without whom we could not publish a credible journal. Specific directions for web-based review on the Manuscript Central web site can be obtained by sending an e-mail to [email protected].

Power Engineering Letters The responsibility for the review of Power Engineering Letters rests with the Editor-in-Chief and the Editors who make up the Power Engineering Letters Editorial Board. The review process is the same as that outlined above for Transactions papers. The Manuscript Central web site for the review of Power Engineering Letters is located at http://pesl-ieee.manuscriptcentral.com.

Proceedings Papers REVIEW OF PROCEEDINGS PAPERS IS BEING DONE VIA THE WEB FOR MOST CONFERENCES. SEE THE PES WEB SITE (http://www.ieee.org/power) FOR DETAILS FOR SPECIFIC CONFERENCES.

Technical Committee Program Chair Responsibility The responsibility for the review of Proceedings papers submitted to a Technical Committee is assigned to the Technical Committee Program Chair (TCPC) for a specific meeting. The TCPC may elect to review the papers personally or be assisted by reviewers. The number of reviewers for Proceedings papers is at the discretion of the TCPC. The TCPC is responsible for obtaining prompt and authoritative peer review(s) of each paper from qualified expert(s) and for evaluating and summarizing the review(s) within the deadline assigned by the Technical Committee. The TCPC for the reviewing committee has the obligation to reject a paper without further review if it does not meet the requirements outlined in this guide. The TCPC is also responsible for putting together the technical sessions sponsored by the committee at the meeting.

Reviewer Responsibility The reviewer of a Proceedings paper has the responsibility to determine if the paper will impart practical, usable information of contemporary interest to the industry. The subject need not be unique or unprecedented, though the theme should be in general keeping with the goals of the meeting for which the paper is submitted. Regardless of the quality of the paper, a paper must be rejected if it exceeds the eight-page limit, inclusive of references, notes, and biographies. The review must be completed and reported within the published time frame.

Acceptance or Rejection Proceedings papers are published as part of the Conference Proceedings of the PES General Meeting where the paper is presented. In addition to meeting the criteria outlined above, a Proceedings paper will only be accepted for the meeting if it: • is submitted in keeping with the published schedules • is submitted in the required formats with the required paperwork • addresses the topic in an appropriate manner • is of a technical rather than commercial nature • is more than simply a restatement of well-known technology • is judged to exceed a qualitative criterion of being elementary or trivial in its presentation • does not exceed the eight-page limit.

The Transformers Committee currently has three general categories of participation in our activities. These are: Interested Individual, Active Participant, and Committee Member. Any one can join our 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. 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 minimum of three WG or SC chairmanships. Detail of the application requirements and approval process by the Administrative Subcommittee is outlined in our O&P manual.

5.3 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. Our 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.

A similar main committee roster has also been developed to track attendance for the Main Committee meeting on Thursdays. The data will be used to update participant’s membership profile.

5.4 Meeting Minutes The minutes of the Toronto, ON Spring, 2010 Transformers Committee meeting were posted to the committee website on March 5, 2011.

See the Treasurer’s Report in Item # 3.7 7.1 Standards Subcommittee Meeting April 13, 2011 San Diego, CA

1. Opening Remarks Following welcoming and introductions, Chair, William Bartley summarized the recent activities of the Transformer Standards activity for the six-month period of Oct 1 2010 to April 1, 2011. The Transformer Committee is responsible for approximately 90 active standards, plus 43 projects for new standards and revisions. For the full STANDARDS REPORT see the TC website (The link is: http://www.transformerscommittee.org/meetings/S2011-SanDiego/Minutes/S11-StandardsStatusReport.pdf). There have several changes at the IEEE to be aware that include changes to the Ballot Process, Changes in personnel with IEEE Staff Liaison - Matt Ceglia having been moved up within the IEEE. Matt’s expert advice and contributions to the Standards SC and TC was recognized by the Chair and our appreciation was noted. The temporary IEEE-SA Staff Liaison is Erin Spiewak. Also, the IEEE International Coordinator is Jodi Haasz. The Chair announced that Vice Chair, Steve Antosz, will be directly involved with the interface for the Standards SC regarding the International Standards coordination. The IEEE TC requirements to have quorum present was reiterated. 2. Meeting Attendance The Standards Subcommittee met on Wednesday, April 13, 2011, at 4:30 PM. A role call showed 25 members in attendance constituting a quorum. Over all 50 attended with, 25 quests including 3 that requested membership. 3. Approval of previous meeting minutes The Chair asked if there were any comments or corrections to the previous meeting minutes, and motioned for approval. There where no comments to the meeting minutes from the Fall 2010 meeting in Toronto, Ontario, Canada; and the minutes were approved. 4. Working group reports.  Cont. Revision of C57.12.00 – Steve Snyder reported the following: This is essentially a working group of one person. There are no meetings. The purpose of the WG is to keep track of and 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 goal is to issue new Standards every 2 to 3 years. Standard C57.12.00 was published September 2010. At present there are no new items known to me. Once it is decided to move ahead with new revisions to C57.12.00-2010 and C57.12.90-2010, then a PAR will be submitted and a revised draft document will be created. Respectfully submitted, by Steven L. Snyder, WG Chair, on April 9, 2011

 Cont. Revision of C57.12.90-2006 – S. Antosz reported the status of as: Introduction This is essentially a working group of one person. There are no meetings held. The purpose of the WG is to keep track of and compile all the work being don in various TF/WG/SC’s for inclusion in the continuous revision of C57.12.90 in a consistent manner. This WG coordinates efforts with the companion Standard C57.12.00 so that they publish together. The goal is to issue new Standards every 2 to 3 years. Past Revisions The most recent publication of C57.12.90 was done in October of 2010. Here is a list of the significant revisions:

Page 1 of 5 7.1 Standards Subcommittee Meeting April 13, 2011 San Diego, CA

 Subclause 5.3. Resistance measurement methods has been changed to promote the voltmeter- ammeter method over the bridge method.  Subclause 5.4. Resistance measurements connections and reporting have been added.  New subclause 9.5.5. Provides a test method for zero-sequence impedance measurement on transformers with interconnected windings.  Subclause 10.2.2.1. Switching impulse wave polarity has been changed to require negative polarity instead of an option between positive or negative polarity.  Subclause 10.3.1.1. Full-wave impulse testing has been completely rewritten.  Subclause 10.3.1.3. Chopped-wave impulse testing has been completely rewritten.  Subclause 10.3.2.5. Nonlinear protective devices has been completely rewritten.  Subclauses 10.5 to 10.10. Low-frequency tests have been revised.  Former subclause 10.10.5. Deleted temperature correction factors of insulation power factor.  New Annex B. Factors for conversions from 50 Hertz to 60 Hertz and vice versa. Future Revisions Changes already approved for the next revision:  New sub-clause 10.2.5 Connection of neutral terminal during switching impulse tests by Pierre Riffon’s WG Revision to Impulse Test in Dielectric Test Subcommittee. Submitted on 4/27/09.  Revisions to Clause 12 Short-circuit tests and new Annex on Connections diagrams for testing three-phase transformer using alternate single-phase source by Marcel Fortin’s Task Force in the Performance Characteristics Subcommittee. Submitted in Fall 2009.  Revision to sub-clause 10.3.2.4 Tap connections during lightning impulse test by Pierre Riffon’s WG Revision to Impulse Test in Dielectric Test Subcommittee. Submitted on 10/28/10. There has been ongoing work in several groups which may result in changes for the next revision. Timetables for completion are not known.  Revision to Clause 11 Temperature-rise tests by Paulette Payne Powell’s WG in the Insulation Life Subcommittee.  Revision to Clause 13 Audible Sound by Ramsis Girgis’ TF/WG in the Performance Characteristics Subcommittee.  Possible revisions of Clauses 6 & 7 Polarity & Phase-relation and Ratio tests from Mark Perkins’ PCS WG for Revision of C57.12.90 in the Performance Characteristics Subcommittee.  Other possible revisions to Sub-clauses 10.2 to 10.4 from Pierre Riffon’s WG for Revision to impulse tests.  Other possible revisions of Sub-clauses 10.5 to 10.10 from Bertrand Poulin’s WG for Revision of low frequency tests.  There was an old action item from 2004 about adding a new clause on Single-Phase Excitation Tests chaired by Bruce Forsyth in the Dielectric Test Subcommittee. This special dielectric test keeps getting lost even though all discussions seem to produce agreement to add the test. Status unknown. Just noting here, if in case someone wants to revive this yet again. Summary As can be seen from the above lists, most of the major clauses of the document have been recently reviewed or are presently in the process of review; therefore, the Standard can be considered to be in pretty good shape.

Once it is decided to move ahead with new revisions to C57.12.00-2010 and C57.12.90-2010, then a PAR will be submitted and a draft revised document will be created. Until then, this WG of one will just wait for the ongoing work to proceed to conclusion. Respectfully submitted, by Stephen Antosz, WG Chair, on April 4, 2011

 PC57.12.70 Terminal Markings Revision – S. Shull – The Chair explained the invitation to ballot on PC57.12.70 Standard Terminal Markings and Connections for Distribution and Power Transformers would be issued this week (actually was issued on Thursday, 4/14/2011) and all are encouraged to participate. WG on Revision of IEEE C57.152 (old 62) –Jane Verner – This was the ninth meeting for this Working Group. After introductions, the attendees totaled 95, (65 Guests, 30 of 53 the Members, and 7 requesting membership) allowing for a quorum. It was asked if any patents were related to the work of the group; there were none. The fall 2010 Toronto meeting minutes were approved. Committee membership was reviewed with regard to quorum rules. Draft 4.1 has been issued and posted on the website. Dan Sauer has offered many comments. We held one web meeting since the Toronto meeting when we discussed the following: Section 6.1.2 - Ratio/ Polarity/Phase: A team comprised of John Herron, Ajith Varghese, Brian Penny, Mario Locarno, Tauhid Ansari and Peter Werelius contributed to the section. This section needs to be added to the draft. John Herron gave presentation on Induced Voltage Testing. Power electronic testing equipment is now available to allow more frequent induced voltage testing of power transformers in the field. Previously this test was primarily a factory test. John provided a preliminary copy of text for the guide. Mark Perkins and Craig Stiegemeier provided comments on the document as well. After comments are finalized they will be added to the Guide. We agreed to add a new section on Applied Voltage Testing. A small task force was nominated to author this section on Applied Voltage. The task force will be comprised of John Herron, Polo Rodriquez, Bill Chiu, Mark Perkins, Bo Blackmon, Charles Garner and Roger Hayes On other new business a request was made to eliminate data such as power factor for new transformers being test. After much discussion it was agreed to include this data as it provides benefits for the users and many test sets are programmed with these limits anyhow. Jerry Corkran also noted several editorial areas where the Draft 4.1 is now different than the parent standard. The WG agrees these items require resolution prior to ballot; and once the PC57.152 guide is published, the continuous revision process should remain synchronized with parent standards to avoid the condition that IEEE 62 is in. The Work Plan spreadsheet has been updated to show progress. All sections have been presented, reviewed and revised except Induced Voltage Testing and Applied Voltage. The document now comprises 35 sections which are authored by many different persons. The document will be reorganized to put Safety closer to the beginning and to flow more logically. For example the core, coils and insulating fluids will be grouped together. Each section that has a parent standard will be sent to the Working Group Chairman for that Standard to review and insure that the proposed draft is in line with parent standard. A 60 day reply period will be given. The WG hopes to finish basic comments and final edits with a ballot among the WG before Boston. Oleg Roizman mentioned that the Moisture in Oil Section has been updated to reflect work of this specific Task Force of relative saturation. He and Miak Koch provided comments and their proposed changes will be discussed in a web meeting in the near future.

 TASK FORCE on IEEE-IEC CROSS REFERENCE – J. Sim - the following was reported: The IEEE-IEC Cross reference report is complete and posted to the website. The report link is: http://www.transformerscommittee.org/subcommittees/standardsc/IEEE-IEC-CrossRef/S11-IEEE-IEC- ComparisonReport.pptx and it will be made available to the IEC, especially TC14, TC36 and a few other committees. Note the report has an embedded completed comparison adobe file that is also separately posted with the following link: http://www.transformerscommittee.org/subcommittees/standardsc/IEEE- IEC-CrossRef/S11-IEEE-IEC-ComparisonDocument.pdf TF Report Summary The comparisons are based on the latest published standards unless identified otherwise It is the directive of the Standards Subcommittee to publish this comparison study each time a major standard (IEEE C57.12.00, C57.12.90, or IEC 60076-1, 2, 3, 4, 5…) is approved and published The purpose of this study is to provide list of major differences between IEEE and IEC standards to the members of the group working on these documents In addition to these major documents, we will include comparisons of other standards and guides commonly used for Power Transformers It is hoped that the readers would consider harmonizing the standards as best as they can as they develop these standards for the industry. Submitted by Jin Sim, in March 2011 The TF Chair recognized the contributions of the TF members ask requested those present to stand and expressed his appreciation of their efforts. The Standards SC voted to accept the report and was so moved, seconded and accepted.  TASK FORCE on IEEE-IEC Harmonization – Jeewan Puri - The TF Chair explained there no meeting and that initial draft of the harmonization procedure that is the action item for the IEEE (Ms. Jodi Haasz) has not yet been received by the TF Chair and there is little to report at this time. Jeewan will continue follow through to determine progress and promote the development of the procedure. The Chair noted the newly appointed Standards SC IEC coordinator will also be to assist in this effort.

5. Old Business No old business was raised. 6. New Business There are two requests for new business was raised.  There was a proposal for new Task Force, presented by Dr. Valery Davydov to development new document called: Moisture in Insulating Systems of Gas Insulated & Liquid Immersed Transformers & Reactors (The link to the presentation is: http://www.transformerscommittee.org/subcommittees/standardsc/NewBusiness/Valery'sProposal- Moisture-NewTF-UnderStdsSC-Extended-ForWebPageOfStdsSC_28Apr11.pdf , in the New Business of IEEE TC Standards SC webpage). Following the questions and suggestions discussion it was agreed the presentation would be posted to allow time for review and then be an agenda item for the Fall 2011 meeting Boston.  There was a proposal by Patrick McShane for a Task Force to create a reference white paper to be used to harmonize the use of fluid, oil, and liquid terminology across all the transformer standards. The motion to vote to form the TF that was seconded & the motion passed. The SC Chair asked if C Patrick McShane agreed to the TF Chair when asked by the SC Chair.

8.3 IEEE Standards Association (SA) Awards and Recognition

The IEEE SA sponsors additional awards besides the WG Chair Awards reviewed above. Discussion of these awards can be found on the IEEE SA Awards web pages (http://standards.ieee.org/sa/aw/). Note particularly the IEEE SA Standards Medallion. Excerpting from the website: “The Standards Medallion is awarded for major contributions to the development of standards. Examples of such contributions may include leadership in standardization of new technologies, assuring achievement of standards development goals, identifying opportunities to better serve the needs of standards users or other such contributions viewed as deserving of this award…” Please review, and if you have suggestions for nominations see our Committee Awards Chair.

8.4 PES Transformers Committee Distinguished Service Award

We will continue to present our PES Technical Committee Distinguished Service Award each year to one of our members who is recognized by his peers as having contributed significantly and consistently to Committee Standards activities. Excerpting from the PES Awards website:

FILE: S11-Awards.doc 2 4-9-2011

AWARDS SC REPORT – Spring 2011 – San Diego, California

“Each Technical Committee is encouraged to make one award for outstanding service. This personal recognition acknowledges the efforts of those individuals whose sustained performance, over many years, has contributed to the advancement of the committee technology.” Please see the Awards Chair if you have suggestions for future recipients. We are seeking nominations for this award.

8.5 PES Working Group Recognition Awards

In addition to the Technical Committee distinguished service Awards, PES sponsors Working Group Recognition awards. The awards are related to “outstanding and timely” publications of technical reports, or of standards and guides. Excerpting from the PES website (http://www.ieee.org/portal/site/pes/) Awards pages: “The PES Working Group Recognition Awards recognize “the most outstanding and timely publications” by a PES Working Group (or Committee or Subcommittee) from among the nominations. The PES Recognition Award is divided into two categories: 1) for technical reports; 2) standards and guides. Each Technical Council Committee may nominate one report from each category, published by IEEE, during the previous three year period.” This award consists of a plaque which will be presented to the Working Group Chair at the PES Summer Meeting Awards Luncheon. A framed certificate will be presented to each Working Group member at a designated meeting of the parent Technical Committee. Each Technical Council Committee is urged to submit one electronic copy of nominations for each of these awards no later than November 27. Please forward suggestions for nomination for the next (2011) PES WG Recognition Award to my attention, ASAP, so a nominee can be selected and forwarded to PES. 8.6 Transformers Committee Meritorious Service Awards

In 2008 we initiated a process of additional recognition for Meritorious Service and Outstanding Contributions to the Committee. Suggested qualifications have been developed from a review of similar awards presented by other IEEE Technical Committees or Societies. General examples for qualification for the awards include the following: • To recognize continuing exemplary service in notable technical contributions to multiple Committee projects/documents over a sustained period of time • To recognize an achievement of major value and significance to the Committee. The achievement can be a specific, concisely characterized accomplishment, as opposed to a collection of different efforts. • As with the IEEE Education Society Meritorious Service Award – “to recognize pioneering contributions to the administrative efforts of the Society over a period of years, as evidenced by dedication, effort, and contributions.” If you have any additional thoughts on qualifications for Meritorious Service Awards, and if you have potential nominees to suggest, please contact me. Award nominees will be reviewed by the Awards Chair and the SC Officers.

AWARDS SC REPORT – Spring 2011 – San Diego, California

8.7 Member Certificates

We will continue with the process of providing a framed Certificate, certifying Membership in the Committee, to new Members. The intent is to provide a symbol of recognition of Membership status, in a format suitable for display. The Certificate will indicate date of acceptance into the Committee, and will be signed by the Committee Chair. We will also send a framed certificate to everyone who is currently a member of the Transformers Committee. It was originally intended to hand these out at the Thursday main committee meeting however in the interest of time we have decided to mail these directly. You should receive your plaque by the end of this year (2011).

This program is one small way of recognizing your support for the Committee. The Certificates represent the appreciation of the Committee, and of your Committee Officers, for your service to the Committee, to IEEE, and to our Industry. We hope you will display your Membership Certificate proudly at your place of business, and encourage others to join us in our work.

8.8 Nominations for IEEE, PES, and Technical Council Awards

There are no nominations in these categories at this time. Regarding IEEE Fellow Nominations, we have missed the opportunity for preparation of nominations for the 2011 Class of IEEE Fellows. We need to think about nominations for 2012. Borrowing from the IEEE Awards web pages (http://www.ieee.org/web/membership/grade_elevation/grade_elevation.html): “The grade of Fellow recognizes unusual distinction in the profession and shall be conferred only by invitation of the Board of Directors upon a person of outstanding and extraordinary qualifications and experience in IEEE-designated fields, and who has made important individual contributions to one or more of these fields.” Nominations, including references by at least five present IEEE Fellows and optional additional endorsements, must be completed and submitted by March 1 of each year for the following year’s Class of Fellows.

10 Subcommittee Reports 10.1 Distribution Transformer Subcommittee Report Chair: Stephen Shull Secretary: Jerry Murphy Meeting Date: 04/13/2011 Time: 9:30 – 10:45 Attendance:

Members 34 Guests 36 Guests Requesting Membership 2 Total 71

Meeting Minutes / Significant Issues / Comments: Steve opened the meeting; rosters were passed out, introductions were made & a roll call of members showed we had quorum with 34 of the 46 members in attendance. The minutes of the fall 2010 meeting of the subcommittee were presented and a motion was made by Ron Stahara, seconded by Said Hachichi to approve the minutes; the motion carried by unanimous acclamation. The following is the reports that were submitted by the Working Groups and Task Forces.  C57.12.20 – Overhead Distribution Transformers The membership requirements of the WG were reviewed. Attendance at 3 of the last 5 meetings or last 2 consecutive meetings is required for membership. Since the Fall 2010 meeting, 4 members have been removed and 7 new members added. Membership stands at 32. Attendance of the membership was taken and 27 members were present and a quorum was established. There were no patents disclosed that impact the work of this WG. The minutes of the Fall 2010 Toronto meeting were approved as submitted. The Chair reported that a one-year PAR extension has been granted by NESCOM. The Chair reported the results of the recirculation of the IEEE Sponsor ballot of PC57.12.20-D7 dated March 2011. • Ballot Open Date:16-Mar-2011 • Ballot Close Date:26-Mar-2011 • RESPONSE RATE: This ballot has met the 75% returned ballot requirement; 92 eligible people in this ballot group. 71 affirmative votes, 5 negative votes with comments, 0 negative votes without comments, 2 abstention votes • 78 votes received = 84% returned 2% abstention • APPROVAL RATE: The 75% affirmation requirement is being met. 71 affirmative votes 5 negative votes with comments • 76 votes = 93% affirmative • Comments: Document should be published by the end of 2011 pending REVCOM approval. • Discussed possible considerations for the next revision including; 1) gasket temperature limits, 2) natural ester fluids, 3) other ratings (e.g. 600Y/347 Volts), 4) tank pressure TF recommendations, 5) bushing requirements, and 6) weights and dimensions. Meeting adjourned at 10:00am

Page 1 of 10 Distribution Transformer Subcommittee Report

 C57.12.28 – Enclosure Integrity Introductions of members and guests No comments were provided to any patent relationships to the standard. A quorum of the Working Group's members was present (22 out of 33). The minutes of the March 9, 2010 and October 26, 2010 working group meetings were approved. A line item review of the C57.12.28 standard was then started. The definition of the Padlock was altered to state that the device will be specified and supplied by the user. Mounting procedures for the installation of pad mounted units were discussed based on a negative ballot received in 2005. Alternative methods were presented and reviewed. However, it was decided by the working group membership, that including an installation procedure was beyond the scope of this standard. Therefore, the security between the mounting surface and the unit will remain the responsibility of the installer-user. A concern was expressed by one of the members related to the security of the locking nut in a case where the penta-head bolt was not included in the closing of a device in the field. A wire could be inserted past the padlock and through the nut allowing contact with high voltage components on the front plate. A statement will be prepared requiring the back of the nut or the threaded bracket be sealed or covered. Two of the working group members reviewed the tools and component parts included in the standard to conduct the enclosure integrity tests. All of these devices and parts are still available for purchase and no changes were recommended. The working group was asked to review a test requirement for the doors to latch when the unit is closed and a lift and place test be added to the standard. After a discussion period, it was decided that the working group chairs would contact the requester and ask for further clarification. A modification was made to section 5.3.2 to require the coating systems to be retested when changes are made to the process or every two years. A problem was identified with the ability of Munsell to provide consistent pad mount green color standards. In Toronto, members were requested to bring samples of the colors currently applied to their products. Several companies provided samples which will be evaluated. Results will be presented at the next meeting. An alternative color standard company was also provided which will be investigated. The meeting came to a conclusion at 9:18 AM.  C57.12.29 – Enclosure Integrity-Coastal Environment The C57.12.29 standard was not discussed at the meeting due to time constraints. However, all of the enclosure integrity tests and requirements were covered during the review of the C57.12.28 standard. These two standards are very closely related and share many of the same features. The membership will be contacted by e-mail related to one issue. There is only one source for outdoor coastal testing since the closure of the LaQue test site in North Carolina. Members will be asked to search for an alternative site and present their findings at the next meeting.

 C57.12.34 –Three Phase Padmounted Transformers Ron Stahara called the meeting to order. To establish a quorum, the member list was displayed on the screen and those who saw their names were asked to hold up their hand. From this count of hands, a quorum was declared. Ron asked that everyone introduce themselves by giving their name, company and location. Also, an attendance roster was circulated. The IEEE Patent Policy was presented to the group by Ron Stahara. The group was asked if there were any patents that needed to be disclosed. None were announced to the group. A motion was made by Jerry Murphy and seconded by Gael Kennedy to accept the minutes of the past meeting. It was approved by acclamation with no corrections. The impedance levels were reviewed for the new sizes of 7.5 and 10 MVA. There was some discussion but only concerning the impedance ranges of the smaller unit sizes. Ron Stahara pointed out that there was a footnote that asked the user to insure that their requirements would be met when using this impedance range or value. There was some discussion concerning the correctness of the table reference but it was generally agreed that these values were acceptable. Steve Shull said he would verify this reference. The next item that was discussed was reference to the 600 A cable termination. Steve Shull explained that Ali Ghafourian had asked the question concerning the arrangement of a 600A elbow (TBody) in the cabinets. This would include proper clearances both horizontally in the cabinet and with the cabinet’s depth. Gary King stated that it appears that the dimensions works now or the users were making it work. The Chair asked that task force be formed to determine what these dimensions should be using the following manufacture’s products a reference: Elastimold, Hubbell Power, Cooper Power System and Richards Manufacturing. As well this group would verify that the secondary cabinet will handle the necessary cabling for these larger sizes. The leader of this group will be Jerry Murphy, and he will be assisted by Gael Kennedy and Chuck Simmons. They will report back to the group in the fall meeting. Gary King brought up the concern of the configuration of the H0/X0, X0, and H0 terminal. He said that his company had a request that they provide a deadfront elbow for this terminal. The group discussed this and determined that operationally this could provide a danger to operating personnel by them getting confused and terminating a neutral on hot phase. The consensus of the group was that a bushing should be used as it now is currently specified currently in the standard. This concluded the meeting.

 C57.12.35 – Bar Coding for Distribution transformers and Step-Voltage Regulators The working group met on Tuesday, April 12, 2011 at 9:30 am in the Toucan Room of the Catamaran Resort in San Diego, CA. There was a quorum present. The chairman reviewed the patent legal issue and asked whether there were any patents or patents pending that would affect the working group or standard. None were identified. The minutes from the previous meeting in Toronto, CA were approved. The chairman gave a summary of the results of a bar code and RFID survey sent to the working group and the distribution subcommittee. A general discussion of the results was held. The chairman asked for a motion NOT to amend the PAR to include RFID requirements in the standard; Bob Olen made the motion, Ron Stahara seconded it and the motion was approved. The chairman asked the group if a task force within the group was necessary to address the RFID requirements. The general consensus was not to form a taskforce because of

Page 3 of 10 Distribution Transformer Subcommittee Report

the results of the survey and the end-users in the meeting did not see the benefit of RFID at the present time. There was a discussion on the use of different type’s scanners. Bob Olen volunteered to propose a modification to Section 4.1.6 to address the use of different types of scanners. The meeting adjourned at 10:30 am.

 C57.12.36 – Distribution Substation Transformers Jerry opened the meeting at 8:00 AM on Monday April 11, 2011, in the Boardroom of the Catamaran Resort Hotel in San Diego; introductions were made, and the attendance rosters were circulated. No new patents were disclosed. Quorum was reached with 12 of the 23 members present. Regarding the status of this working group, Jerry informed everyone that a PAR had not been approved yet, and therefore, anybody in attendance had the opportunity to request membership in this soon to be Working Group. There was a question of whether the present standard could be reaffirmed. Steve Shull informed the group that IEEE was in the process of changing the policies for revising standards. The proposal effective Jan. 1, 2012 is the reaffirmation process would be eliminated. He recommended that a new PAR be obtained. The minutes of the fall 2010 meeting were presented and a motion was made by Ron Stahara and seconded by Gael Kennedy to approve the minutes. Motion passed unanimously. Jerry mentioned the work for the new revision would be based on the comments made during the past balloting process. It was anticipated that most of the discussion would be focused on reviewing the requirements of accessories, considering the requirements of this standard, as well as those of the recently published C57.12.10-2010 standard for power transformers. Carlos Gaytan made a comment concerning the tank designs of these 2 standards regarding tank withstand and pressure relief. He pointed out that a comparison would be presented at the meeting of the Task Force on Tank Pressure Coordination. Jerry asked the group if they had any comments to send them to him, and he would work on having the PAR approved for the next meeting in Boston. The meeting was adjourned at 8:40 AM  C57.12.37 – Electronic Test Data Reporting The meeting was called to order at 1:45pm in the Board Room at the Catamaran Hotel, San Diego, CA. Introductions were done. Roster was taken, and a quorum was not met. The Chairman will work to reduce the membership to those who are involved before the next meeting. Minutes were reviewed but could not be approved because quorum was not met. The chairman asked if anyone was aware of any patents that might affect the development of this standard. No patent disclosures were made. Old business: The changes to the standard were reviewed. It was asked if any other changes were known. None were offered. The document will be sent to ballet and review before the next meeting. New Business: None We adjourned at 2:05pm.

Page 4 of 10 Distribution Transformer Subcommittee Report

 C57.12.38 – Single Phase Padmounted Transformers The meeting was called to order by Ali Ghafourian. A roll call was conducted to determine if a quorum was present. Twenty-four (24) of the thirty-four (34) working group members were present. Therefore, a quorum was present. The members were asked if there were any patent issues that needed to be identified associated with the work on this standard and none were identified. The minutes from the October, 2010, meeting in Toronto were presented for review and were approved. Significant changes made in Draft 1.2 were discussed as follows:  In Figures 1C and 2C, the last two lines of the tables were revised to reference the applicable figures in IEEE 386 for the small (Figure 7) and large (Figures 8 and 9) interface connectors. This was in response to a suggestion from the Fall 2010 meeting. The change was deemed acceptable except that since referencing tables in another standard, the date of the standard referenced should be used. This will be done in the Normative References.  Figure 5 was added to the standard which shows low voltage bushing arrangements for the various low voltages now covered by the standard. At the Fall 2010 meeting there was discussion about whether or not the 240/480 volt and 120/240 volt bushing arrangements should be included. No decision was reached at that meeting. A motion was made (Ron Stahara) to include Figure 5 in the standard with the addition of 277/480 volts, which was missing, and seconded (Gael Kennedy). The motion passed with no opposition.  There was additional discussion about the possibility of including in the standard information on the amount of weight that the low voltage bushings can support. A group consisting of Justin Pezzin, Giuseppe Termini, and Chuck Simmons will study information available on this subject from bushing and transformer manufacturers and report back to the working group.  It was pointed out that Figure 4, Detail C for the low voltage terminal stud sizes had not been revised to reflect that the standard now covers up to 250 kVA units. It was also pointed out that since the standard now covers more low voltage levels, the stud size requirements need to be based on amperage rather than kVA size. This will be reviewed and incorporated before the Fall meeting. The meeting was adjourned at 11:40 p.m.  C57.15 – Step Voltage Regulators At our last discussion at the C57.15 Fall meeting in Toronto we indicated an informative ballot in the IEC community for consideration of IEEE C57.15 for the IEC IEEE dual logo process laid down in AC 138, 2002 was given in May 2010. The purpose of this circulation was to make sure there were no inconsistencies between C57.15-2009 and any existing IEC TC 14 standards or projects. The result (14/642/INF - May 2010) of the inquiry (14/637/DC) was to adopt IEEE C57.15 as a dual logo standard. Nine (9) countries provided comments in addition to their vote while 18 countries voted without additional comments. 12 countries did not respond at all. Our Working group for C57.15 provided formal responses back to the countries that had provided comments regarding consideration of C57.15-2009 being a dual logo candidate. Discussion regarding these comments on C57.15-2009 acceptance and a dual logo candidate was discussed at the TC 14 plenary meeting in Beijing, China - November 2010. The chairman of IEC TC14, Paul Jarman, proposed that IEEE C57.15 should be submitted for vote for adoption as a dual logo standard under the IEEE/IEC agreement. All members present at the TC 14 meeting, except Japan, agreed to this proposal.

Page 5 of 10 Distribution Transformer Subcommittee Report

Under the terms of the IEC-IEEE Agreement, the General Secretary submitted the following IEEE products to the SMB (STANDARDIZATION MANAGEMENT BOARD) Submission Procedure. This submission to the SMB of the IEEE product is in accordance with Stage 2 of the procedure for the IEC-IEEE Agreement. As background information, Stage 1 was the submission of C57.15-2009 to the IEC General Secretary by the IEEE. This circulation to the IEC Standardization Management Board (SMB) is for a Question of Principle (QP) ballot. This ballot asks the members of the IEC SMB if the document should be submitted to IEC TC14 for vote as a Final Draft International Standard (FDIS). The closing date for this ballot was 1 April 2011. This was the next to last step in having the document adopted by IEC TC14. A Report (SMB/4456A/RV - 2011-04-04) of voting on document SMB/4456/QP was provided. Decisions of the Standardization Management Board taken by correspondence requires a two thirds majority of those voting, abstention is not considered as voting. In this case, 8 members of the Standardization Management Board voted in favour, 4 voted against with 2 abstentions and 1 no reply. The SMB has therefore approved the 1 IEEE Product Std C57.15-2009, submitted under the IEC - IEEE agreement for publication as a double logo IEC/IEEE standard under the work programme of IEC TC 14, for its circulation under the fast track procedure at FDIS Stage, the last stage of the process. For information only, comments on the QP for the Submission of IEEE product IEEE Std C57.15, under the IEC/IEEE agreement for publication as a double logo IEC/IEEE standard for consideration as dual logo candidate under the work programme of IEC TC 14 was as follows.  The Japan National Committee was not in favor to support this document because limits of temperature rise of a power transformer indicated in Clause 5.2, Table 2 of the document under consideration, which is based on an IEEE Standard, are different from those of the IEC International Standard 60076-2. The IEC International Standard under consideration shall not define different values from those of the other IEC International Standard on the same subject.  The Italian NC is interested in the document because a similar document does not exist in IEC TC 14. Anyway, we do not support the IEC-IEEE dual logo process, because the document requires a review to adapt it at IEC world (for example voltage levels, temperature rise limits, tests values shall be adapted for IEC standard values).  Countries who voted for IEC acceptance of C57.15-2009 for dual logo were Austria, Canada, Germany, United Kingdom, Korea, Mexico, Netherlands and United States.  Countries who voted against for IEC acceptance of C57.15-2009 for dual logo were China, France, Italy and Japan.  Countries who abstained from the vote regarding IEC acceptance of C57.15- 2009 for dual logo were Spain and Sweden. No reply from Brazil. Stage 3 is submission to IEC: If the result of the vote on the FDIS is positive, then the document is published. Steve Shull stated that this was the first dual logo IEC/IEEE International Standard and asked the Committee to give Craig a round of this accomplishment.

There was no new business. The next meeting is planned for the fall in Boston. The meeting adjourned at 4:43 PM.  TF – Tank Pressure Coordination Carlos opened the meeting at 3:15 PM on Monday April 11, 2011, in the Boardroom of the Catamaran Resort Hotel in San Diego; introductions were made, and the attendance rosters were circulated. No new patents were disclosed. Quorum was reached with 22 of the 30 members present. The minutes of the fall 2010 meeting were presented and a motion was made by Ron Stahara and seconded by Marcel Fortin to approve the minutes. Motion passed unanimously. Under Old Business, the status of the definition of Static Pressure Requirements was reported. The Standards C57.12.36 and C57.12.10 were added to the comparison table. In the fall 2010 meeting there was a discussion about the concerns that users had expressed about the PRV’s flow rate for large distribution transformers. On the updated comparison table of particular interest from C57.12.36 and C57.12.10 was the consideration of Pressure Relief Devices (PRD). PRD flow rates are based on standard air (SCFM), but will typically release a combination of both oil and air. There is no conversion available to estimate true flow for mixed fluids (air / oil). Carlos asked the TF if there was a need to define an additional device for medium power transformers with flow rates between the PRV’s used in distribution transformers and PRD’s used in power and large distribution transformers. Carlos formed a group of PRV manufacturers for evaluation of PRV flow rates, and the following people agreed to participate:  Christopher Sullivan - Heartland  Josh Herz - Qualitrol  Justin Pezzin - IFD Corporation This group will convene sometime before the next IEEE committee meeting via a conference call. Carlos will coordinate this call. Participation from other transformer manufacturer’s representatives is welcome. Giuseppe Termini mentioned there are no specific requirements for PRDs on single and three phase submersible transformers but he asked if this task force could cover this type of transformer. Carlos included this in the Task Force’s scope of work. He asked that they consider all types of distribution transformers. Under New Business, the TF discussed Dynamic Pressure Requirements. Marcel Fortin made a presentation on Arc testing in distribution transformers as discussed in C57.12.22 which was specified originally for cover retention and oil spill testing. There was some discussion about the construction characteristics of the different types of distribution and power transformers. It was pointed out distribution Transformers have flexible walls, while Power Transformers have very rigid walls because they are required to withstand full vacuum filling. A copy of this document as well as the other documents on static pressure will be posted on the website of the Distribution Transformer Sub-Committee. Pad mounted fusing practices were discussed and comments from two manufacturers in the TF estimated that approx. 20% of padmount transformers built use a bay-o-net fuse and current limiting fuse (CLF) for protection, while the rest use a bay-o-net fuse and isolation link. A summary of the status of the WG Tank Rupture & Mitigation PC57.156 was presented. There was some discussion about how this task force could work in coordination with the PC57.156 Working Group.

Page 8 of 10 Distribution Transformer Subcommittee Report

Steve Shull asked the group if it would be beneficial to establish a scope and purpose before the next meeting and attempt to move the TF into a WG. Dan Mulkey felt it would be good to keep all the requirements in one standard. (i.e. combined with Power transformers). John Herz commented that the TF which had now become the PC57.156 WG may include in its version tank design or other methods for mitigation of tank rupture. He asked if this TF really wanted to expand our scope to include these types of items. Ali Ghafourian suggested the task force keep the PARs separate to ensure this TF can keep some control of development of this new distribution guide. Alan Wilks, Steve Shull, and others agreed that for distribution transformers we didn't need to mirror the scope of the PC57.156 WG. Ali Ghafourian made the motion to create a PAR for the TF to move it into a working group, and define the title, scope and purpose for this new WG. This would be presented for review at the next meeting. Motion was seconded by Marcel Fortin. Motion carried with no one opposed. Carlos will prepare these items with the input of other these members to be presented at the Fall 2011 meeting. The meeting was adjourned at 4:25 PM. Old Business: Steve addressed the changes coming from the Standard Board as they will be eliminating the Reaffirmation and stabilization options. The reason was Ballot resolution groups simply dismiss comments on technical flaws by stating “reaffirmation doesn’t allow changes”. First, we don’t have any stabilized standards. Any reaffirmation must be done now. Starting in 2012, standards will have 10 year life. They must be complete ballot in the 10 year time frame. Details will be worked out later this year but the indication is the PAR extension will not keep the Document active. Brian Klaponski questioned this plan. He stated that he was concerned that the distribution transformer standards will lose their continuity and the individual knowledge that we currently retain by doing our standards through continuous revision. He asked that we express this concern and ask this plan be reconsidered. Not other action was taken on this comment. Steve made a request and encouraged all attendees who were not members of the IEEE, Power and Energy Society, Standards Association, Transformers Committee and the Distribution Transformers subcommittee to please consider doing so. Steve pointed out for those who think they are members to check their badges. If they find they don’t have Committee Member ribbons on their nametags, they are not Transformer Committee members. New Business: Jerry Corkran brought up some safety information for those working in wind farms as ice which formed on the turbines and turbine blades has fallen and has caused significant damage to padmounted transformers located at their bases. This can be a very real hazard to those working near this location. Jerry Corkran made a motion to request a change of the language in C57.12.90 so as not to require back to back heat run tests. He requested that this be in the form of a letter from this subcommittee to the Working Group (Paulette Payne). Brian Klaponski brought up the history behind this in that many members of the Dist SC do not attend the C57.12.90 meeting and are likely not aware of these issues. Marcel made a motion to amend this motion to add a comment requesting Paulette to include the Distribution Transformer SC members in any survey that she would issue on this standard, Said Hachichi seconded and 22 members voted in favor thus carrying the motion and adding the amendment. Phil Hopkinson pointed out that back to back heat runs are the most realistic testing method for simulating actual operations. Said Hachichi commented that at Quebec Hydro they have compared the two methods and found no difference in the testing. 27 members voted to pass the amended motion with no negative votes. Therefore Steve Shull, will send a letter to the Subcommittee chair with a copy going to the Working group chair requesting that this test not be mandatory and change

Page 9 of 10 Distribution Transformer Subcommittee Report

the wording from “preferred method” to “alternate method” and also request that the Distribution Transformer Subcommittee be included in any surveys that C57.12.90 may issue. Marcel questioned how we can improve the communication between the other subcommittee meetings. Steve and Jerry recommended that the best way is to attend the Thursday full committee meeting. A motion was made and seconded to adjourn the meeting with unanimous consent. The meeting adjourned at 10:41am.

10.2 Dielectric Tests Subcommittee – Loren Wagenaar, Chair; Thang Hochanh, Vice- Chair; Dennis Marlow, Secretary

The Dielectric Tests Subcommittee (DISC) met on Wednesday, April 13 at 11:00 am in the Catamaran Hotel, with 174 persons in attendance. There were 75 of 119 members, and 99 guests present. 13 of the 63 returning guests who requested membership will have their participation status reviewed prior to acceptance

10.2.1 Chair’s Remarks

1. The Chair briefly reviewed highlights of the Administrative Subcommittee meeting held on Sunday. He indicated that it is possible that the review period for standard renewal may change to 10 years and that the reaffirmation process may be eliminated. He also indicated that our present IEEE program manager, Matt Ceglia has been promoted and we will have a temporary replacement. The last day for Revcom submissions is Oct 17, 2011, and this date may be critical if the new changes are adopted later this spring.

2. The Chair indicated that next meetings of the TC are:

a) Fall 2011 October 30-November 3 (Renaissance Boston Waterfront $159) – Boston, MA - hosted by Omicron b) Spring 2012 , TBA USA

3. The original roll call of committee members showed 47 members were in attendance at the start of the meeting. The new quorum requirements were not met originally and it was decided to perform another role call later. This was done after the report on Impulse test procedures and with 68 members in attendance the quorum requirements were met. The membership participation will be again reviewed prior to the next meeting to include only active members. All WG and TF should update their rosters prior to the next meeting.

4. The minutes of the Fall 2010 meeting in Toronto were approved with a correction to the spelling of one members name and are available on the IEEE Transformers Committee Web Site.

10.2.2 Working Group Reports

10.2.2.1 Task Force on External Dielectric Clearances Eric Davis, Chair; Dennis Marlow, Secretary

The TF met on April 11, 2011 at 9:30 am at the Catamaran Resort Hotel, San Diego CA. with . 74 people attended this seventh meeting, 6 members and 66 guests (26 repeat guests) were present with 5 requests from repeat guests for membership. Membership stands at 20. We did not have a quorum. Consequently, the minutes from the Toronto meeting in Oct 2010 could not be approved .The membership list will be verified further to include only those participants who have attended 2 of the last 4 meetings.

The minutes from the fall 2009 meeting in Lombard, IL and the spring 2010 meeting in Houston was sent to the active members for approval by email but we only received by 8 replies. The secretary will follow up with the unresponsive members to obtain official approval by email.

S11 Dielectric Tests Subcommittee Page 1 of 7 Dielectric Tests Subcommittee – Unapproved Meeting Minutes April 13, 2011, San Diego CA

The IEEE patent disclosure requirement policy was discussed. Reference to the package posted on the IEEE Transformers Committee Web site was made. None of the members and guests present during the meeting was aware of any patents related to the work of this TF.

The Chair apologized to the membership for not circulating the survey which will be sent out to the members and interested guests plus the DI SC for review so that comments can be obtained about the proposed clearance table.

As there were many first time guests we reviewed some of the points that had been discussed at previous meetings. The following points were also discussed during the meeting:

 The clearances we are developing are not the required clearances determined by an engineered device such as the bushing to bottom flange ground nor the surge arrestor phase to phase clearances. These clearances are determined by the manufacturer of these devices.  The surge arrestor and bushing can influence each others field if they do not have sufficient distance between them.  Suggested clearances for two particular manufacturers of surge arresters were received from Juan Castellanos. This document gives good examples of the necessary arrester phase to phase, arrester top to bushing top and arrester bottom to bushing mounting flange clearances.  The TF felt that the clearances provided in the table should govern unless the transformer manufacturer received approval from the Purchaser. A note will be added to the table indicating that in certain cases it may be permissible to use clearances from surge arresters and bushing less than those contained in the table.  The table will indicate phase to ground and phase to phase clearances for various voltage classes based on required BIL and Switching surge values.  A C57.12.00 ballot comment was referred to this TF. The comment was: Table 11: It is the only place that requirement for 1100 kV nominal system voltage are given. Such networks are not in service yet. It is premature to make any standardization regarding this system voltage level.  The general consensus of the TF was that the TF should propose phase to ground and phase to phase clearances for 1100kV. The SC does not have to include these clearances in C57.12.00  It was noted that the present table 11 did not show any phase to phase clearances for 765 and 1100 kV system voltages. Loren Wagenaar suggested that we do not included them since most transformers of this voltage class are single phase. The following note already address this point: o c Power transformers, at nominal system voltages of 765 kV and 1100 kV, are usually single phase so that clearances between live parts of different phases are not an issue

Meeting adjourned at 10:25 am. Respectfully submitted, Dennis Marlow

Loren Wagenaar indicated that since this TF has indicated that changes are necessary to C57.12.00 Table 11 that it will become a WG and that the change of status to a WG should be initiated. A PAR is not required since the resulting work will be included in the next revision of C57.12.00.

10.2.2.2 Task Force for Partial Discharge in Bushings and Voltage/Current Transformers –Thang Hochanh, Chair; Arturo Del Rio, Secretary

The Task Force minutes are included in the WG for Low Frequency

10.2.2.3 Working Group for Revision of the Impulse Test Guides C57.98 and C57.138 Art Molden, Chair; Joe Melanson, Co-Chair

1. The meeting started at 9:30 AM on Tuesday April 12th, 2011 with 57 attendees present, of which 7 were members and 50 were guests.

2. The IEEE Patent Policies were presented and reviewed with the group. The group was polled to see if there were any known patent issues to disclose relative to this standard. None were indicated by any of the attendees.

3. There being 7 members present a quorum was declared and the minutes of the fall meeting in Toronto were approved.

4. The results of our first ballot were that of the 203 comments received, 22 were negative. Of those 22 negative comments 20 have been resolved, 2 still remain outstanding.

5. The negative comment resolutions as proposed by Chair Art Molden were presented to the members and the members agreed with the wording of those proposed resolutions. The two outstanding negative comments were then discussed.

6. One of the two outstanding negative comments was in regard to the use of a lower case “e” and an upper case “E” used to represent voltage in an equation included in the Guide. The negative voter had suggested that “V” should be used in all cases. General consensus is that either “V” or “E” can be used to represent voltage in an equation but that “E” is generally used to represent voltage sources where as “V” is generally used to represent a circuit voltage response. The members were all of the opinion that we should be consistent with our terminology and continue to use “E” and “V” as is the case elsewhere in the document.

7. The other outstanding negative was regarding the naming of a function used in the Annex section of the Guide on “Advanced Processing of Digital Records” and named a “Reliability Indicator”. The negative voter believed that the function so named was in fact the “Coherence Function” and should be named as such. Bertrand Poulin, the author of this document provided an explanation of the difference between the two functions which will be passed on to the negative voter in the hope it results in approval.

8. On receiving affirmation of approval on the two outstanding negative votes the Guide will be revised and sent out for a recirculation.

9. This completed the presentation of ballot responses, there being no more business the meeting was adjourned at 10:19 AM

COMMENTS FROM SC MEMBERS

Loren Wagenaar thanked Art Molden and his working group for the work done in the completion of this guide.

10.2.2.4 Working Group on Revision of Low Frequency Tests – Bertrand Poulin, Chair; Bill Griesacker, Secretary

The WG met on Tuesday April 12th at 1:45 pm with 14 members and 46 guests in attendance. The quorum was not met. Minutes of the past meetings could not be approved.

The report on the task force on partial measurements on bushings and instrument transformers was presented by Thang Hochang. The main topic of the TF meeting was a presentation by Alexander Kraetge on possibilities offered by processing of pd signals digitally acquired. Several ways of extracting meaningful data from noisy environments were shown. Next, Thang presented his view on the layout of the future document. Some discussions followed and several people agreed to contribute to the document. It is hoped that some of the sections would be ready for discussions before the next meeting.

Next, the Chairman mentioned that the tutorial session on partial discharge measurements would be held at the next meeting in Boston. Three members volunteered to make presentations at the tutorial.

As old business, the Chairman mentioned that a proposal for induced test on 69 kV transformers would soon be surveyed within the Subcommittee stating that 69 kV transformers must receive low frequency test as Class II transformers since a recent survey showed that the majority of transformer manufacturers were actually testing those as Class II transformers nowadays.

There were no items of new business.

The meeting was adjourned.

10.2.2.5 Working Group on Revision of Impulse Tests – Pierre Riffon, Chair; Peter Heinzig, Vice-Chair

The WG met on April 12 26, 2011, from 3:15 pm to 4:30 pm. Twenty members (20) members and eighty-seven (87) guests attended the meeting. Required quorum was met. Eighteen (18) guests requested membership. The meeting was chaired by Pierre Riffon, chair of the WG.

The agenda has been reviewed and two New Business items were added. The agenda has been approved as modified.

S11 Dielectric Tests Subcommittee Page 4 of 7 Dielectric Tests Subcommittee – Unapproved Meeting Minutes April 13, 2011, San Diego CA

Revision1 of the minutes of the Toronto meeting were approved as modified (name spelling corrected).

The IEEE patent disclosure requirement policy was discussed. None of the members and guests present during the meeting were aware of any patents related to the work of this WG.

The first technical item of business was to discuss the results and comments received from the 2nd survey made within the WG and the Dielectric Tests SC on the number of impulses to be applied during impulse tests. The proposal requests to increase the number of full impulses from one to three as required by IEEE and IEC standards on insulation coordination and HV testing and to align the impulse testing procedure with IEC 60076-3. This survey was made in March 2011. The return rate was 25.9% and approval rate was 82.7%.

Comments received were discussed and the following decisions were taken:

- Coordination with the Bushings SC will be made;

- No specific time interval will be specified between the last chopped-wave and the following first full-wave. The wording will only say that this time shall be minimized;

- Front time for impulses applied on neutral terminals will be put as a New Business for future meetings;

- Tail time tolerances for impulses on neutral terminals will be added;

- Tap position for impulses applied on neutral terminals will be put on New Business for future meetings;

- Two full-wave impulses will be specified after chopped-wave tests during the lightning impulse test sequence defined when protective devices are an integral part of the transformer. This modified proposal will be surveyed within the WG and the Dielectric Tests SC prior to the next meeting;

- Both chopped-wave tests and full-wave tests will be required for design, duplicate units and routine tests;

- Most of the negatives received cannot be resolved because there is no compromise possible;

The majority of WG members presents during the meeting agree to send the proposal to Steve Antosz for inclusion in the next draft of C57.12.90 that will be circulated for ballot.

On new business, there were two subjects. The first was related to the comments received on the last C57.12.00 ballot. Comment received from Kimberly Mosley was discussed and the WG agreed that proper references to clause 5.10.7.2 to be added. A proposal will be circulated to the WG prior to the next meeting.

The second new business was related to a request from Dennis Marlow to discuss the need or not to specify a mandatory order between lightning impulse tests and switching impulse tests. This subject has been slightly discussed but the WG ran out of time and this discussion will be resumed at the next WG meeting in Boston.

The meeting adjourned at 4:30 pm on April 12, 2011.

10.2.2.6 Task Force on Electrical Partial Discharge Measurements Guide C57.113 - E. Lemke Chair

The TF did not meet as the document is being published

10.2.3 Liaison Reports

10.2.3.1 High Voltage Test Techniques (HVTT), IEEE Standard 4 - Arthur Molden

The latest draft of the revised IEEE Standard 4 and 4 of the 5 Annexes that will be included with it, are presently being reviewed by the members of the working group. Depending on the outcome of the members review the document will then be prepared for its first ballot.

Respectfully Submitted: Art Molden.

Bertrand Poulin noted that the new method of analysis of the oscillations on the impulse wave is being changed by both IEC and IEEE. The software for the K factor will need to be changed when the new impulse standard is approved. A member from Europe indicated that there may be some delay in issuing this change in the relative IEC standards and also that the manufacturers may have a delay in updating the software. It is thus anticipated that there may be a period of grace before it is compulsory to adopt the new K factor

10.2.4 Old Business

10.2.4.1 There will be a tutorial on PD measurements at the Fall 2011 meeting.

10.2.4.2 George Frimpong is chairing a new TF for Dielectric Frequency Response Testing presently under the PCS SC. The purpose of the TF is to establish whether the science involved is ready to be put into a guide or a standard, and if so, the TF will recommend the proper SC in which the resulting WG will be placed. He has been given a time limitation of 3 meetings to complete his report and has made good progress after only one meeting. George will give a liaison report at the next meeting.

10.2.5 New Business : There were several comments received from the last revision of C57.12.00 ballot. Pierre Riffon and Eric Davis are addressing these comments in their WG/TF sessions at this meeting.

S11 Dielectric Tests Subcommittee Page 6 of 7 Dielectric Tests Subcommittee – Unapproved Meeting Minutes April 13, 2011, San Diego CA

10.2.5.1 There were 3 comments about the Dielectric Test Tables which still need to be resolved. Phil Hopkinson will address these comments with an Ad Hoc committee and report back to the SC at the next SC meeting

10.2.5.2 Thang Hochanh brought to the attention of the SC that there appears to be a problem with the calibration of new PD equipment when used for RIV ( microvolt reading) This should be calibrated according to NEMA 107. He has offered to organize an inter laboratory comparison method and will provide a standard means of making this comparison between test labs. He has seen results which can be as high as 6 times the actual at 100 microvolt reading..

S11 Dielectric Tests Subcommittee Page 7 of 7 MINUTES OF THE MEETING OF THE HVDC CONVERTER TRANSFORMERS & SMOOTHING REACTORS S.C. IN SAN DIEGO, CALIFORNIA, APRIL 11, 2011

On April 11, 2011, the HVDC Converter Transformers and Smoothing Reactors S.C. met at 1:45 p.m., in the Rousseau E-W Meeting Room of the Catamaran Resort Hotel, in San Diego, California. There were 12 members and 13 guests present. The total membership of the SC is 26, but includes 3 corresponding members. Therefore there was a quorum. The following are the highlights of the meeting:

1. Introductions were made and the attendance list circulated.

2. The minutes of the Toronto, Ontario meeting were approved.

Note: The minutes of the San Diego SC meeting will not be approved until the SC meeting in Boston.

3. IEEE patent policy was reviewed and no issues were raised.

4. The Chairman provided a synopsis of the Administrative SC meeting.

5. The Chairman, as a follow up to e-mails, stated that he was retired from full time employment and that it was his intention to step down from his position as chairman of the HVDC SC at the end of the year or at the latest at the end of 2012. In preparation for this action the chairman asked for a volunteer to become vice chairman/secretary of the SC. As no one volunteered the chairman stated that he would ask SC members to consider the position and let him know if they were interested. The chairman also stated that he would talk to long time SC members re this position.

6. The converter transformer standard IEEE C57.129 will reach its “end of life” at the end of 2012. Discussions took place re future revision work. Since HVDC projects are now in service at 666kV and 800 kV it was agreed that the focus of this revision work should be to extend the applicability to 1100 kV. Should the voltage test tables be extended to these levels or should test levels be specified on a project basis. Another alternative may be to include equations to calculate test levels. IN order to provide more background Ulf Radbrandt volunteered to make a presentation at the Boston SC meeting on test levels; with a focus on higher HVDC operating voltages. At this point in the meeting more discussion took place re IEEE”s proposed new 10 year life for standards. The chairman stated that he would attempt to find out more re the details.

6. Les Recksiedler made a PowerPoint presentation on converter transformer failures that he was in the process of investigating. The purpose of the presentation was to provide background re possible future SC work projects or modifications to test code in IEEE C57.129. To-date Les had insufficient information from the failure investigation re root cause to define any possible test code changes. However this presentation prompted discussions re other possible work areas for the SC. Since there are many old HVDC systems in operation life assessment is an issue. CIGRE are doing work in this area; life assessment of converter transformers and oil-immersed SMRs. Should the SC consider a life assessment guide or can this be handled in an annex? Design review was also discussed as a possible vehicle to prevent premature failures such as those experienced and covered in Les’ presentation. CIGRE has published a design review guide in booklet format. Should the SC consider producing a design review guide or should the subject be covered in some detail in an annex in both IEEE C57.129 (Note that a brief annex is included in the current version.) and IEEE 1277? This presentation will be posted on the Transformers Committee website with the minutes.

The Chairman requested that SC members prepare presentation material on future work for the Boston meeting as a basis for discussion and to provide more direction for future revision work on IEEE C57.129 and IEEE 1277 and/or guides on design review and life assessment.

The meeting adjourned at 3:00 p.m.

10.4.1 Task Force Report: PARTIAL DISCHARGE IN BUSHINGS AND VTs/CTs

The task force on Partial Discharge in Bushings and VTs/CTs met on Monday April 11th, 2011, at 3:15pm with 45 attendees. Of those, 10 were members and 35 were guests with 7 guests requesting membership.

The meeting was opened with a request for patent disclosures and introductions. The minutes for the F10 Toronto meeting were presented. The next item in the agenda was a presentation by Alex Kraetge: De-noising and pulse separation approaches based on synchronous multi-terminal frequency measurements. A request was made to have all the presentations delivered to date in the TF meetings posted on the Transformer Committee webpage; the request was accepted since the material is considered public domain. After the presentation by Mr Kraetge, the TF Chair presented a preliminary scope and a proposed outline for the guide. Among the comments to the preliminary scope presented by the Chair were: o The scope limits the guide to wide band detection, whereas narrow band could also be suitable considering the simpler propagation patterns found in the equipment under test. o Both wide band and narrow band detection are presently being used in laboratory settings by manufacturers. o The scope should be limited to laboratory settings for now and consider field PD measurements for future work. o The scope needs to be re-worded to address the above comments. Regarding the proposed outline, the following comments were made: o What instrumentation is appropriate for PD testing needs to be addressed. o The proposed outline includes a separate sections for CTs, PTs and bushings. Is it really necessary as CTs and bushings are very similar regarding PD testing? o Most of the material that it is currently part of the annexes such as calibration, test procedures and PD pattern recognition should be moved to the main body of the guide and decide later if an annex is needed for additional information. TF Chair Thang Hochanh requested volunteers to start drafting the different sections of the guide. Additional volunteers willing to contribute to the guide can contact Mr. Hochang:

10.4.2 Working Group on Current Transformers with mA range (PE/TR/PE/TR/Instrument-WG C57.13.7) - Henry Alton

The WG met on April 12 at 11 AM. There were 16 in attendance and there are now twelve members.

The agenda was as follows;

1. Introduction 2. Patent Issues 3. Personnel a. Vuong Nguyen has retired b. Adnan Rashid is not Attending 4. Acceptance of the Agenda 5. House Keeping Henry Alton of Triacta Inc. a. Henry Alton to get a copy of C57.13.6 - completed b. Henry Alton distributes latest Measurement Canada spec. - completed c. Henry Alton Generate a Draft framework of C57.13.7 - completed

6. Presentations. a. Brief Discussion CT type suitable for this standard by Dave Wallace ABB Inc. b. Draft Review Comments i. Proposal to remove the parallelogram Randy Mullikin MERAMEC Electrical ii. Paul Millward wanted to test the CT samples provided by Triacta iii. Entertain Transducers?

7. Next Steps a. Look for other values of CT under 250mA secondary or expression thereof b. Close any further testing i. Express results ii. Express methodology c. Timelines for a draft availability for formal reviewing d. Submit for formal reviewing before the next meeting e. open

Old Business The Housekeeping of the previous meeting actions were reviewed. • A copy of C57.13.6 was acquired • The Draft of C57.13.7 included the latest version of the Measurement Canada requirement and was distributed to the team, two weeks prior to this meeting for comments from within the working group.

New Business The topic of seeking coverage of a wider range of CT with 250mA secondary current and below was introduced and Dave Wallace spoke about a component that ABB makes that would be accurate and usable below 250mA secondary. There was some debate about the fact that this device was still a 5A nominal output design. More investigation is required to look for CTs that have secondary output below 250mA. If no more applicable CTs can be found in this category, the first formal reviewable draft of C57.13.7 would be offered up for review with the present content.

Randy Mullikin raised the question of being able to express the limits of the parallelogram in a different form. This was discussed. Paul Millward stated that the present parallelogram most completely expressed the limits. This will be kept open to see whether it should be changed.

Standard burdens were also discussed and a point was made about specifying impedance based on VA instead of these standard burdens. There is a need to investigate the test fixtures being developed by the National Research Council of Canada (NRC) to see whether there would be any impact in using this alternative (any considerations of standard burdens that may have been designed into the fixture). The burden rating numbers in the table should be clarified. This will be dealt with in the actions.

There were comments made with respect to the classes of accuracy given in the draft document that would potentially be very hard to meet. It was further mentioned that cable length could significantly influence the measurement accuracy of a metering device with CTs presenting such low secondary currents. Concerns about the operating environment being included in the test set-up was mentioned. The Measurement Canada regulatory requirement addresses some of this and will be re-iterated. There was also a question about what kind of materials were used in these CTs. There was some feedback that there were typical materials used. Some information on this will be provided.

How accuracy calculations were performed was also raised. A specification TFDEX 27575 was mentioned as an accuracy calculation method.

Paul Millward asked about the Power Factor limits that the 80mA CTs had been tested against. This item will be dealt with in the actions later in this document.

Actions from this meeting These are the actions from this meeting. The dates shown are targeted dates that the action item will be completed by. • Dave Wallace to recover the CTs and forward them directly to Paul Millward. o Status/Date: As soon as possible. A definite date will be sought. • Dave Wallace to provide some test data on the CTs previously tested by Vladimir Khalin. o Status/Date: TBD - a reasonable date needs to be fed back for this. • Henry Alton to provide some information on the materials used. o Status/Date: Apr20/11 • Working Group to provide some more clarity on the burdens and make them more “Real World”. • Henry Alton Some background clarifying the standard burden numbers will be given to support the previous action. o Status/Date: Apr28/11 • Henry Alton to provide the specification limits for signals immunity tests that would be present when an energy measurement is being made. o Status/Date: Apr28/11 • Paul Millward to provide some test results on the same CTs that were being evaluated by Dave and Vladimir. o Status/Date: TBD – Paul to provide a time frame based on receiving the CTs

Schedule Perspective for Completion This perspective was provided on the time still needed to complete the first draft for formal review. • Triacta will conduct formal testing against the Measurement Canada requirement for 200A – 80mA CTs. o Target Completion - June 30/11 o This information can be summarized and shared with the working group • The C57.13.7 document can be left open until the above date to look for other values of CTs that fit this category and demonstrate their results in the same time frame. • The document will be ready for and begin it’s formal IEEE review process after this date.

10.4.3 Working Group for Revision of IEEE C57.13 Instrument Transformers – R. McTaggart

This working group met for the first time on April 12 with 24 people present, 18 of whom became WG members under the 1st meeting rule. Membership expectations were discussed and agreement reached that Survey responses etc would be due 6 weeks after being sent out. The first one, which is for each member to review a portion of the standard, was presented and explained. P. Riffon requested that the Standard be made available in WORD format to facilitate cutting and pasting for this exercise.

The general objectives for the revision, based on previous discussions were discussed: • Improve format – separate VT & CT clauses. o This will be addressed after substantial agreement on content • Resolve differences between C57.13 & C57.13.5 o See below • Add appendix on Bushing CT’s o Draft available for comments • Replace clauses 8.1.7 to 8.1.10 o Draft available for comments • Eliminate obsolete information • Improve PD requirements section • Clarify various clauses o 3 items above to be accomplished through review & discussion

The key issue of how to resolve the differences between C57.13 and C57.13.5, which has been a topic in the last couple of ITSC meetings, was discussed again. The options appear to be: • In C57.13, refer to C57.13.5 for all test requirements for units 115 kV & above • Copy all requirements of C57.13.5 into C57.13 • Define 2 classes of test requirements within C57.13. One class would have test requirements defined in C57.13 and the other class would be compliant with the requirements of C57.13.5 This question will be resolved in a survey as part of the first assignment

Some suggestions for areas for improvements received prior to the meeting were discussed, including: 1) Adding the accuracy class designation 0.15 o Should requirements of C57.13.6 be included? 2) Current transformers with capacitance tap o Cap tap requirements for HV CT’s should possibly be added 3) Voltage transformer used for power supply (PVT's or SSVT’s) o There are requirements up to at least 300 kVA – some with metering or protection requirements as well. There was some debate about the use of a device to compensate for the power loading to maintain metering accuracy. These transformers are generally supplied by Instrument Transformer manufacturers but are in effect small power transformers so they could possibly be addressed in C57.13 or another existing standard or may be best addressed by a stand-alone standard – either under C57.13 or C57.12. D. Wagner & D Wallace will collect spec’s etc for review. 4) Ground fault CT's o Requirements for GFCT’s for insulation failure detection on HV CT’s should possibly be added 5) It was noted that no wet tests (either AC or switching) are required for units of 362 kV or above (see Table 2) 6) Table 15, subsection c (Voltage transformer burdens) – needs clarification o Items 5 & 6 above to be accomplished through review & discussion

Other subjects discussed included Transient Performance requirements, which are seldom specified in the USA. A simple solution is to make reference to IEC 60044-6 as is done in C57.13.5.

The issue of sensors for distribution system control was discussed. These sensors may be conventional instrument transformers as covered by C57.13 or non-conventional instrument transformers. Typically they need to have 0.6% to 1% accuracy and sometimes need to have protection accuracy as well. A clause defining this dual performance could be added to our standard. Marcel Fortin mentioned that there is a WG in the Switchgear Committee which might include this. Following the meeting he looked into this and found that there is a draft for C37.68 being worked on. However it is for microprocessor based controls for distribution equipment and does not take in voltage and current sensors. The general question of non-conventional instrument transformers also came up but this cannot be addressed in this revision. A separate standard or adoption of IEC would be more appropriate - with deviations if necessary. If we want to proceed with this a TF should be created.

The IEEE Patent disclosure requirements were discussed and a request was made for disclosure of any patents that may be related to the work of the WG. There were no responses to the request for disclosure.

Approval of minutes from the Fall 2010 Toronto, Ontario meeting was requested. The minutes were approved as written.

Report of work done since last meeting:

Rick Ladroga gave a recap of the chairs of the various TFs that have been initiated. 1. Arc Furnace – Chair Tom Lundquist 2. Framework – Chair Jim Dukarm, Vice-Chair Dave Hanson 3. Data – Chair Norman Field, Vice-Chair Pierre Feghali 4. Case Studies – Chair – Paul Boman, Vice-Chair Arturo Nunez 5. Diagnostic Methods – Chair Michel Duval, Vice-Chair Dave Wallach 6. Bibliography – Chair Jerry Murphy, Vice-Chair Tom Prevost Rick indicated that he would like to have short regular meetings with these groups to help keep the Guide on track.

1. Discussion Forum: Claude Beauchemin

Claude discussed the on-line forum for discussion of issues that has been set up. He encouraged members to sign up on the e-mail that he had set up. The next step will be to open the forum up to guests as well.

2. Data Analysis: Norm Field and Jim Dukarm

Norm Field gave a recap of the work done to day. He indicated that he had underestimated the time that this would take by a considerable amount. Much of the time has been spent cleaning up the data rather than analyzing it to date.

The data so far comes from 10 sources and has recently added a couple more. They began with 590,000 DGA samples. After editing , they have 292,000 high integrity DGA samples representing approximately 97,000 transformers.

Editing included removing blank or nonsence items, removing non-mineral oil entries, removing duplicate entries, removing OEM lab data (factory test), and verified that an ID#, Sample Date, Breathing Type, kV, and MVA were included.

For comparison to Table 1 of 104, the individual gas concentration data was analyzed with respect to percentile values.

Presented first, a simple calculation showing the 90th, 95th, and 98th dissolved gas percentile points. The data below is before any outliers were removed. The values are provided in ppm. There is much that needs to be refined, stray gassing also needs to be addressed.

A request for other percentile points was requested to allow comparison to what CIGRE has put together.

Norm indicated that he would welcome any help that he can get. Luiz Cheim offered to help.

Jim Dukarm also gave a report on the exploratory statistics that have been done as the data has been cleaned up. He indicated the goal will be to have a large, clean database that can be archived to support the values eventually used within the Guide. This would then be available for any future revisions to the guide.

3. Case Studies: Paul Boman

Paul provided four case studies.

The first was for a Turn-to-Turn Winding Fault, No-Load Tap Changer Fault, Unintentional Core Ground Fault, and a High Voltage Phase-to-Ground Fault. He also has put together instructions for using the Roger’s Ratio and Duval Triangle methods.

Paul requested that if there are any other case studies that anyone wishes to suggest, to please let him know.

Sue McNelly volunteered to review the writing portion to make sure that the case studies are clearly written and understandable to the user.

The meeting was adjourned at 4:30 pm.

10.5.2.2. C57.130 Trial-Use Guide for Dissolved Gas Analysis During Factory Temerature Rise Tests for the Evaluation of Oil-Immersed Transformers and Reactors. WG Chair Jim Thompson

The WG Report Given at the Sub-Committee Meeting:

Presented by Tom Prevost. No patent declarations. The document was on Draft 18 when the decision to let expire was made. The WG will begin where the previous group left off and will be starting with a new Draft 19. A listing of variables were listed, including winding types.

The Minutes (unapproved) of WG Meeting as Submitted:

Unapproved Minutes of WG Meeting

The working group meeting was called to order by Chair Jim Thompson on Tuesday, April 12 at San Diego, California with 64 people in attendance, including 15 of 30 members present.

There was a request for patent declarations regarding the PC57.130 document and none given.

This document was in draft 18 when the decision was made to let the PAR expire in 2009. A new PAR was approved on June 17, 2010 and is labeled Draft 19.

The current document was placed on the overhead media projector and members volunteered for Sections 1 through 6 of the document. Sue McNelly volunteered to export the draft document into an IEEE template. The data request for DGA during factory temperature rise tests was discussed in terms of the various parameters of interest. These included: MVA, cooling type, test duration, voltage class, oil volume, different loading rates over time of the test, identification of laboratory used, permanent overload specifications, no load losses, and the difference between C57.90 and C57.119 regarding the factory tests at greater than one per unit rated load.

Jin Sim mentioned that the previous guide draft issues included – limiting the trial-use guide based on minimum gallons, gassing differences related to winding types (e.g. disc versus layer designs), various loading rates during factory tests, and relatively small gas values as opposed to reproducibility between labs.

The Power Point© presentation, the current draft of the document, and the previous negative ballot comments will be posted on the Insulating Fluids Subcommittee web site. Respectively submitted,

Chair Jim Allen Thompson Vice Chair TV Oommen

C57.139 - Draft IEEE Guide for Dissolved Gas Analysis of Load Tap Changers

Tuesday, April 12, 2011 San Diego, California Minutes of WG Meeting

Fredi Jakob called the WG meeting to order at 11:00am. WG Vice-Chair Dave Wallach and Secretary Susan McNelly were also present. There were 20 of 35 members (Quorum requirement was met). There were 59 guests present with 7 guests requesting membership.

Guests requesting membership were:

Josh Herz Arturo Nunez George Forrest Dan Sauer Jesse Inkpen Prabhu Soundarrajan George Leinhauser

Fredi thanked the group for its efforts in getting the Guide through the ballot process. Fredi indicated that he can no longer guarantee that he would be able to attend. He has asked Dave Wallach to take over as chair of the WG.

Agenda: 1. Welcome and Introductions 2. Patent Disclosure Request 3. Approval of Minutes from Fall 2011 Toronto, Ontario, Canada 4. Guide Status 5. PAR to revise 6. Items for consideration in the next revision 7. Review Work Assignments.

Approval of minutes from the Fall 2011 Toronto, Ontario, Canada meeting was requested. The minutes were approved as previously submitted.

Guide Status: IEEE Std C57.130-2010 was published February 18, 2011. PAR

PAR for revision has been drafted. The plan is to submit the request for PAR in the coming weeks and on approval, continue work in Boston in the Fall of 2011.

The need for the project: There are presently no industry guidelines to support user’s trending of DGA data for load tap changers. The WG proposes the next revision to consider data collected in the industry from the initial issuance and further develop some concepts the WG could not consider with the development of the initial guide.

Concepts for the next revision:

Ballot comments that were not incorporated into the last document will be reviewed for inclusion in the next version.

Data - Additional data from the WG members will be needed to develop generic design category norms.

Is there a variation of norms between utilities (users) with the same type of equipment? Temperatures Loading practices Maintenance practices

What about inclusion of graphical interpretation methods? Triangle (Duval) Nomograms (Jakob-Dukarm)

Past suggestion; presence of Benzene and Toulene: The high ratio of Ethylene to Acetylene indicates problem of overheating. Then it is necessary to check for Benzene and Toulene. Presence of Benzene and Toulene indicates the contact wear and deformation of the metal contact in the Diverter chamber, which may be the cause of overheating (Submitted by Vijayakumaran, Senior Technical Expert, AREVA, Allahabad, India 211008).

A comment was made by Fredi that he would need to see some real justification for the addition of Benzene and Toulene.

General comment from ballot Just as we do with transformers we liberally use the word “fault” to encompass lots of things, some of which aren’t faults in the truest sense (like coking, that’s not a “fault”). We propagate this in the standard (there is a long history here). Should we consider “anomaly”, a “potential hot spot” anything but a fault. Any discussions here would have to be coordinated with C57.104 and other DGA guides (e.g. Natural Esters).

Direction should come from Insulating Fluids Committee

Presentation by Jim Dukarm on Where do we go from here?:

Kinds of Statistical Limits: The current statistical method for deriving LTC DGA limits provides a way to classify gas concentrations and gas ratios as: Unexceptional or Unusually high or Extremely high relative to a specific population of LTCs. In a clean population, "unusually high" might signify a fly speck. In a dirty population, it might signify a near-failure condition. What we would like is something more like this: Normal or Medium or High (probability of failure in near future) This would require a good amount of failure data.

Use of Statistical Limits: Some with LTC field experience believe that it is advisable to require a certain amount of gas (beyond 10 ppm) before a gas ratio is taken seriously. Very low gas levels probably signify low operation frequency, so even if a ratio indicates bad contact condition, perhaps the actual risk of failure is still low. Confirmation of ratio-based fault indication is continued increase of ratio beyond "warning" level. We conjecture that this may be a way of distinguishing non-fault- related high ratios in resistive LTCs from fault-related ones. C2H4/C2H2 and CH4/C2H2 ratio limits can be plotted as straight lines on the LTC Duval Triangle as indicators of when an abnormal condition is "interesting" enough to motivate action.

Graphical Methods: The C57.139 Guide as it stands does not provide much guidance on fault detection. Duval Triangles (LTC for arcing-in oil and Transformer for vacuum types) may be useful for this. A gas ratio nomogram is also available.

There was discussion that in addition to DGA, a sentence or two should be added to the Guide regarding the fluid quality.

10.5.2.5. Task Force (Study Group) PC57.147 Guide for the Acceptance and Maintenance of Natural Ester Fluids in Transformers

TF Chair Patrick McShane, Vice-Chair Clair Claiborn, Secretary Jim Graham

The Group Report Given at the Sub-Committee Meeting:

Patrick McShane presented at the meeting. He presented the background of the formed group for the purpose of developing a PAR submittal for the 1st revision of IEEE Standard Guide C57.147. There was some confusion on the proper term for such a group formation. Traditionally for existing standards reaffirmation and revisions they have been called WGs within the TC, but according to IEEE SA they should be called Study Groups until a PAR is issued, which should occure within 6 months of forming the SG. The plan is to finialise the PAR application and submit to IEEE SA asap. It will require at least one additional webcast meeting.

There was some discussion on whether the PAR should include synthetic esters. However, an IEC Standard exists specifically for synthetic esters and due to the limited use in North America, it was suggested that this may be a possiblitity for collaboration with IEC.

Non-Approved Minutes of TF Meeting:

The Task Force meeting was called to order at 8:15 AM on April 11, 2011. Introductions were skipped due to time limitations, and an attendance roster was circulated. As this was the first meeting of the task force, membership has not yet been established. There were 61 meeting participating, 21 of which requested joining the new Study Group for the development and submittal of a PAR to revise the current standard published in 2008. The chair asked if there were any patent disclosures, and none were disclosed. The chair gave a summary of the issues raised in the balloting of the document, and the status of the ester fluids related task forces created by the original working group. The task force for field application of natural ester fluids submitted a PAR for working group status, but the application was rejected. The chair presented a proposed scope for the revised document and asked for comments. Bill Chiu suggested deleting the last sentence re precedence of the guide’s recommendations vs. manufacturer's instructions. This suggestion was supported by an affirmative straw vote. Tom Prevost raised an objection to including diagnosis of apparatus single this document is primarily a fluids guide. After a lively discussion pro and con, it was pointed out by John Luksich and confirmed by Loren Waagnar that field testing and diagnosis of ester fluid filled apparatus is being addressed by the C57.152 working group. The scope was amended to resolve Mr. Prevost's objection. The revised scope was affirmed by a straw vote of the attendees. • Draft 1 Scope: This guide recommends tests and evaluation procedures, as well as criteria and methods of maintenance, for natural ester-based insulating fluids. These base fluids are also known as vegetable seed oils. Methods of reconditioning, field applications and diagnostics of natural ester-based insulating fluids are also described. The chair then presented the proposed purpose, but due to time constraints only a limited discussion took place. The only comments from the floor suggested the purpose should be simplified and reduced in length. No action was taken. The chair discussed the issues from the last ballot in more detail and outlined a plan to create a set of sub-groups each assigned to review and amend certain portions of the existing document. Sub-group members and chairs will be established once working group status of the parent task force is achieved. Suggest Task Forces Pending PAR approval: • TF 1: Section 4 - Fluid tests & … significance • TF2: Section 6 - Handling & evaluation of NE as received • TF3: Section 7 - Evaluation of NE as received in new equipment and after filling … on site. • TF4: Section 8 – Field Maintenance of NE • TF5: Annex B – Additional Technical Info • TF6: Field Application Guide and Equipment Evaluation • TF7: Miscellaneous - All other Sections The meeting adjourned at 9:15 AM.

10.5.2.6. PC57.155 – Guide for Interpretation of Gases Generated in Natural Ester and Synthetic Ester Immersed Transformers

Chair Paul Boman, Secretary John Luksich

Report given at the Sub-Committee Meeting by Paul Boman:

Paul requested additional data be submitted to the WG on any DGA of Natural and Synthetic Esters. One area of special interest is data from any failed power class transformers with esters, as reported at the last WG meeting, only one is on record that involved severe overheating after the first operation of a stuck non-energized tapchanger in a aged retrofilled GSU transformer. He thanked David Hansen for his presentation in Toronto on TJH2b’s experiments with DGA analysis of natural esters.

Minutes (unapproved) of the WG meeting as submitted:

Meeting Date: April 12, 2011 Time: 9:30 AM

Attendance: Sixty attended, including 14 members out of 46 members. 5 people requested membership.

- Quorum not present - intend to approve minutes on-line or at next meeting with quorum - No patents - review fall 2010 minutes; no comments or corrections

Continued business

- Fluid OEMs supplied fluid samples to TJ|H2b, Weidmann Diagnostic Services, and Doble Engineering. Some samples needed to be re-sent.

- Jerry Murphy supplied unused fluid from a 5-year old tote kept in his transformer yard. The tote was under a tarpaulin for the first three years, then in direct sunlight.

Presentation: Michel Duval showed a stray gas ternary plot using hydrogen, methane, and ethane and plotting soybean transformer fluid stray gases at various temperatures from unrelated sources. At 55C, mostly hydrogen was present. At 200C, mostly ethane was present. Michel suggests that it may be possible to detect overheating using these stray gases only.

Presentation: Dave Hanson showed follow-on results to data shown at the last meeting. Fluid from a tote exposed to diffuse sunlight for 2 ½ - 3 years showed low concentrations of gases attributable to photo-effect oxidation. Fluid exposed to direct sunlight for one week had significant concentrations of stray gases attributable to photo-effect oxidation. Discussion - Claude Beauchemin: The fluid exposed to sunlight for one week had quite high gas levels. Would exposure of a syringe to sunlight for an hour be enough to alter the gas concentrations?

- Chairman: Perhaps have a sunlight warning for post sample container handling in the guide. - Fredi Jakob.: A first assumption is that the effect is linear. A week’s worth of sunlight is about 70 hours. An hour’s worth would be 1/70 of the concentration seen in the one-week sample. This is probably not significant. Ultraviolet light will not penetrate the glass syringe.

Dave Sundin.: The acid value in one of the samples seems high.

Michel Duval.: What was the temperature of the tote?

Jerry Murphy.: Probably around 30C.

Chairman: Tote samples went to two other labs. We’re waiting for those results.

Update on 200 MVA transformer failure

- Michel Duval: the transformer was retrofilled with natural ester fluid, had complications (overheating) due to higher viscosity and required water spray, a frozen tap changer was forced, and elevated gas levels resulted shortly thereafter.

- John Luksich: The transformer was manufactured in 1968. Was told by the owner that the transformer was overheating shortly after installation and required water spray.

- Jim Graham: Is familiar with the transformer. It was not overheating. Someone put their hand on the tank, thought it was too hot, and added water spray. He could never convince maintenance that the transformer was not overheating and did not require water spray.

Other Items - Marc Cyr: Have Ostwald coefficients been adequately established? - John Luksich: EPRI presented their findings early on but have not yet issued a final report. Jocelyn Jalbert published a paper with his findings.

Jalbert, J., Gilbert, R., Tétreault, P., El Khakani, M.A., "Matrix effects affecting the indirect calibration of the static headspace-gas chromatographic method used for dissolved gas analysis in dielectric liquids", Analytical Chemistry, Vol. 75, No. 19, October 1, 2003, pp. 5230-5239

- Michel Duval: For method C, CIGRE recommends using gas-in-oil standards to calibrate the equipment rather than using published partition coefficients.

- Marc Cyr: It would be helpful to include the coefficients calculated using the gas-in-oil standards along with the dissolved gas data so that WG members can review them. Labs should get the same coefficients if they operate using the same conditions (temperature, pressure). Including the coefficients with the data will allow the WG members to critique or correct the gas data we end up publishing in the guide.

C57.637 – IEEE Guide for Reclamation of Insulating Oil and Criteria for Its Use

Tuesday, April 12, 2011 San Diego, California, USA Minutes of WG Meeting:

The meeting was called to order by Chair Jim Thompson at 8:00 am on Tuesday, April 12 at San Diego, California with 31 people in attendance and with 12 of 19 members present. This document was reaffirmed in 2007 and the PAR for revision was approved December 10, 2008. Working Group member Jim Thompson (Chair) conducted the meeting. There was a request for patent declarations regarding the PC57.637 document and none given.

There was a motion to approve the October 26, 2010 Working Group minutes by Dave Sundin and a second by Don Cherry. The approval of the minutes was unanimous. The discussion of the meeting included use of the IEEE template; deletion of dates associated with referenced published standards unless a specific document text was unique; referencing the moisture parameters in the C57.106- 2006 guide that are similarly referenced in the IEEE C57.637 guide; moving the Askarel trade names to the appendix; and adding a footnote to the ASTM 4059 test method to make readers aware of additional PCB isomers that are not listed in that test method. There was also discussion about the media used in reclamation and possibly separating that text into different sections in the guide. The Power Point© presentation will be posted on the Insulating Fluids Subcommittee web site and Draft 2 will be emailed to working group members.

Respectfully submitted,

Chair Jim Allen Thompson Vice Chair TV Oommen

10.5.2.8. TF on Particle Count Limits in Mineral Oil

Mark Scarborough– Chair, T.V. Oommen- Vice-Chair , Paul Boman - Secretary

The Report given at the Sub-Committee Meeting:

Mark Scarborough presented. There is significant interest in the issue of particle count in insulating fluids as there were 67 in attendance of the TF meeting, of which 8 requested membership. Mark briefly reviewed the purpose and scope of a potential PAR application. He then went into detail regarding the result of a survey on the topic sent to 475 persons, of which 71 responded. There was discussion about the possible posting of his Power Point presentation of the survey results. It was observed that 66% of the responders do not have particle limit requirements.

Discussion at the TF included pros and cons of setting a standard for new insulation fluids as received, new fluid in a new transformer, and limits for in service. A motion was made, but not seconded during the TF meeting to dismiss the TF. Clair Claiborne clarified the origins of the ASTM standard related to particle count. Harold Moore stated that it can be useful as a diagnostic tool. TF meeting minutes (unapproved) as received:

Mark Scarborough– Chair, T.V. Oommen- Vice-Chair, Paul Boman - Secretary

Meeting Date: April 11, 2011 Time: 1:45 – 3:00 PM

Attendance: 19 members out of 36 members were in attendance, total attendance was 67 and 8 people requested membership. At the beginning of the meeting during roll call we only had 16 members present, so the meeting proceeded as without a quorum.

The meeting was called to order at 1:45 PM. Attendance rosters were circulated.

The following agenda was followed:

1. Introductions & Roster 2. Patent Disclosure 3. Origins 4. Activities Since Fall 2010 Toronto Meeting 5. Member List / Quorum 6. Approval of October 27, 2010 Minutes 7. Purpose / Scope 8. Survey / Survey Results 9. Summary of Survey 10. Next Steps / Discussion 11. Adjournment The IEEE Patent Disclosure policy was reviewed. No patents were disclosed. Attendee introductions were made by group. Since we did not have a quorum at the beginning of the meeting, we were not able to vote on the approval of the October 27, 2010 Fall Meeting Minutes as written. The Chair sent out a survey request to all TF Members and asked them to vote. Only 5 have responded. All responses were positive. TF Members are requested to access survey sent via e-mail and vote on the approval or disapproval of the meeting minutes from October 27, 2010. Purpose and Scope were reviewed and an on-line survey vote was e-mailed to TF Members. TF Members were requested to access the survey and respond by April 22, 2011. The on-line Particle Counting Survey issued October 18, 2010 to 475 individuals received 71 responses as of 3/24/11. Chairman reviewed particle count on-line survey responses question by question showing the results. The presentation has not been made available on the IEEE Transformer Committee – Insulating Fluids web site. Further discussion with the Insulating Fluids Chair on posting the results is needed. The survey results have been normalized by the chairperson contacting individual respondents asking for clarification on responses. Not all respondents replied and it was noted on the presentation. Sample bottle cleanliness standards were discussed. Additional review of this information needs to be performed by the TF. Discussion comments after presentation: Marc Cyr supplied information on bottle cleanliness as listed in ASTM D6786-08 Section 8.1 as repeated below.

ASTM D6786-08 does have a sampling procedure. This is to be reviewed by the TF. TF is to looking into feeding back comments to ASTM on the standard. Don Platts made comments concerning survey: • About 66% of the respondents do not have particle limits. • Does not agree with many of the results of the survey. • Large number of survey questions invites confusions (>6 questions) and conflicting results. • Respondent #4 under Question #24, 25, and 26 cited purchaser’s specification has been written to help manufacturer to pass acceptance testing. • Purchasers should not be dictating particle count limits to manufacturers. There are other tests such as ASTM D1816 that is sensitive to particles and particle counting should not be used as an acceptance test parameter. • Supportive of particle counts as a diagnostic tool but not supportive using particle counts as part of an acceptance test. Don Platts put forth a motion to disband the Task Force. No one seconded the motion to disband the Task Force. Others in the audience suggested that the Task Force step back and look at what is really valuable from particle counting. Chair asked for origins of ASTM D6786 - Standard Test Method for Particle Count in Mineral Insulating Oil Using Automatic Optical Particle Counters Clair Claiborne provided historical background on the ASTM method. Harold Moore commented that particle counts are an important diagnostic tool but does not believe limits are needed at this time. A request has made to several labs to mine their data bases samples that have been tested for particles. Two other attendees stated that particles are very important to HVDC transformers.

10.5.2.9. TF on Moisture in Oil

Chair: Bob Rasor

The TF Report given at the Sub-Committee Meeting:

Sue McNelly presented for the TF. Congratulations were expressed for the TF Secretary Hali Moleski’s new arrival, Ella. The meeting achieved a quorum. He stated that the TF has been reviewing a lot of data that has been submitted including both from on-line monitors and lab results. Also several presentations of various studies have been made to the TF. The goal for the next meeting is present a summary of the information received to date. It was mentioned that additional data would be welcome, especially including temperature of the mineral oil at time of sampling and the dissipation factor.

The TF Meeting Minutes (unapproved) as Received:

TF on Moisture in Oil Monday, April 11th, 2011 3:15 pm San Diego, California U.S.

The meeting was called to order by Chair Bob Rasor at 3:20 pm. There were 72 attendees. 29 of the 48 members were present. Four requested membership.

Members attending were: Bob Rasor Dennis Allan Claude Beauchemin Paul Boman Dinesh Chhajer Stephanie Denzer James Gardner Jorge Gonzalez de la Vega Gary Hoffman Tony Pink Donald Platts Jin H. Sim Brian Sparling Jim Thompson Mark Tostrud Mike Cau Juan Castellanos Donald Cherry David Hanson Zan Kiparizoski Terence Martin Thomas Melle Oleg Roizman Barry Ward Shuzhen Xu Stephan Brauer Beugh-Olof Stemestam Jesse Inkpen Ray Bartnikas Valery Davydov

Attendees requesting membership were: Clair C. Claiborne Jitendra Mamtora Paul Caronia Marc Cyr

Agenda 1. Roster was distributed 2. No patents were disclosed after the documents were posted and the question posed 3. Role call was taken 4. Reviewed scope 5. List of recent conference calls were given 6. Presentation was given that included i. Brief description of task force ii. Review of minutes from previous conference were displayed (unanimously approved) iii. Summary of moisture in standards/guides iv. Review of past data 1. Data from EPRI study from Drs. Roizman and Davydov with temperature, ppm an saturation 2. KF and temperature data from Bob Rasor v. New data presented 1. Data examples from both online monitors, % sat, and moisture removal and calculation from Bob Rasor 2. On-Line monitor and Karl Fischer results were presented by Claude Beauchemin

In summary, the TF presented data to demonstrate the many trends that can be seen with moisture and how all data parameters may need to be considered.

Data was presented from online monitors and Karl Fischer testing. It was noted that top oil relative saturation can be much different than bottom oil relative saturation.

Data examples also demonstrated that moisture content (ppm) responds to temperature and that that season affects moisture data. Relative saturation was shown to stay relatively stable as compared to moisture content on these graphs. Data also supported that relative saturation could be more consistent when compared to only the water content (ppm).

When oil temperature increased, water content also increased dramatically, often shifting between acceptable and unacceptable levels within days.

7. A summary of concepts and plans for future data 8. Discussion and questions followed 9. Meeting was adjourned at 4:30pm

Comments provided at the end of the meeting regarding the presentation include the following:

• It was asked if is it possible to take dissipation factor (tan delta) into consideration with moisture data to observe correlation.

• It was suggested to perform a saturation study on a single transformer at various different and extreme temperatures in addition to the various transformer data.

• The shifts in calculated ppm vs. relative saturation appear to be different in the presented graphs. This is possible due to the time period of data, a larger time period graph will look different.

• It was asked if there was a standard deviation in the graphs demonstrating seasonal differentials.

• Some emphasis should be placed on what temperatures are being used for analysis (i.e. top, bottom or average oil temperatures).

• The increase in saturation after a demonstrated increase in temperature and ppm was explained because the temperature drops faster than the water reabsorbed- thereby increasing the saturation reading for a short period of time.

10.5.3. Old Business:

Patrick McShane is reviewing TC Standards and Guides for the various nomenclatures used for transformer dielectric coolants with the intent to create uniformity, obvious omissions of various alternative fluids in existing C57 standard, and areas where revisions may be necessary in existing standards based on the suitability, or unsuitability, of alternative fluids based on typical property differences with the standard mineral oil. The SC home for such a task force, while focused on insulating fluids, belongs in the Standards SC and the subject is scheduled to be discussed as new business at the 4-13-11 Stds SC meeting. 10.5.4.

There were 28 of 55 members present (a quorum was achieved) and 44 guests. New requests for membership will not be entertained due to the Guide having gone to ballot. However, anyone who has volunteered to work on the ballot resolution group will be added to the membership list.

Agenda: 1. Roll Call/Introductions 2. Patent disclosure announcement 3. Previous meeting minutes approval 4. Status of the present Guide 5. Adjournment

Introductions of members and guests were made.

Minutes from the Spring 2010 meeting in Houston, Texas and Fall 2010 meeting in Toronto, Ontario, Canada were approved.

Status of the present Loading Guide: The Guide was set to expire and be withdrawn at the end of 2010. A PAR extension until the end of 2011 was requested and approved at the December NESCOM meeting.

Draft 9 Ballot summary: Draft 9 was balloted with 218 comments, 82 as must be satisfied. The ballot met the 75% return requirement with 97% affirmative rate. Draft 10 has incorporated many of the comments that were received.

Don indicated that the next step will be to form a ballot resolution group to review the remaining technical comments received during the ballot process. A request for a ballot resolution group (BRG) was made and the following have volunteered: Don Duckett, Carl Arpino, Sue McNelly, Dave Wallach, Juan Castellanos, Don Platts, Craig Colopy, Peter

2 Balma, and Tom Prevost, and Roger Verdolin and Tim Raymond will be contacted to see if they are willing to help out.

Brett Sargent volunteered after the meeting to review Annex J and propose updates. Depending on the extent of the proposed changes, any revision may need to wait for a future revision.

Since there was time during the meeting, the WG went through most of the remaining technical comments from the ballot and resolved all but about two or three. This will make the work of the BRG much easier and will help push the document forward after a quick review of the changes made since the last ballot by the BRG. Don Duckett will be making arrangements for conference call with the BRG in the near future to go through any remaining comments and the changes made to the document.

10.6.3.2 Working Group On Thermal Evaluation Of Power And Distribution Transformers (C57.100) – Roger Wicks

The Ballot Resolution team has met a number of times since our ballot closed in order to develop a revised document that can be successfully recirculated.

We met Monday during the working group scheduled time to continue this work. We have a plan on the elements to complete this revision, but the “devil is in the details”. These details are still in the process of being worked out.

Specifically, we are addressing standardizing the sealed tube test (adding specificity) as well as documenting a process for assigning new life curves (based on IEEE 1) for new insulation systems. This was outside of the scope of our document in previous versions of this document, and in our balloted document wasn’t as clear as it needed to be. This is of importance today due to the interest in new insulation systems for our power transformers.

The ballot resolution group should be commended for all of the work in this effort – Don Platts, Tom Prevost, John Luksich, Terry Drees and Jin Sim.

10.6.3.3 Task Force on High Temperature Liquid-Immersed Transformers (PC54.154) – Richard Marek

The sixth meeting took place on Monday, April 11, 2011 in the Rousseau Center Meeting Room at 1:45 pm, at the Catamaran Resort Hotel, San Diego, Califonia. Introductions were made and attendance sheets were circulated. The new IEEE patent policy was discussed and there were no concerns regarding patents. At 36 members, a quorum was established with 20

3 members and 70 guests present. The minutes from the Toronto meeting were approved as submitted.

Waldemar Ziomek presented the results of the Task Force assigned to resolve issues with Fig 3 of Draft 5, which has now become Fig 5 in Draft 6. The recommendation included revisions to the sketch and Waldemar will provide a marked up copy according to the Task Force agreement along with the results of a series of questions.

George Frimpong presented data that showed a temperature advantage of aging of cellulose in the natural ester over mineral oil. He is supporting the Task Force charged with developing an informative annex that presents a convincing argument for this thermal enhancement. The Task Force Chair, Jin Sim then addressed the group noting that the results will be prepard by August. This is important to make sure the content is included in the upcoming survey of the Insulation Life Subcommittee.

The Chairman then reviewed the changes to Draft 6: - The number of insulation systems was reduced to three - The use of windings was introduced as a means of explaining these systems A comment was made by Hasse Nordman questioning the need for high-temperature stress rings. The Chair ageed that this was a mistake and it would be corrected. A discussion followed on the tables with allowable temperature rises, methodology, temperature classes of individual components and rules for combining materials - Notes concerning shell type were added - The revised temperature limits tables were reviewed

The question was again raised whether the document is a standard or a guide. Gary Hoffman asked if he could make a motion to vote on the question. The Chair declined his offer for a vote but agreed to add this question to the upcoming survey of the Insulation Life Subcommittee which is scheduled to be competed before the fall meeting. His reason for declining was that an earlier show of hands indicated that very few of those present had read the latest draft and so it made no sense to ballot the working group on this topic.

Two guests asked why they were not granted membership. The Chair noted that since the work is well over half complete no new member were being accepted. He also noted that all documents go to all guests as well as members, so membership is not necessary. However, several guests said that they did not receive the last mailing. The Chair said that he uses the List Server and agreed to check the cause.

The meeting adjourned at 3:05 pm.

10.6.3.4 Working Group for Temperature Rise Test Procedures Section 11 of C57.12.90 - Paulette Powell

The Working Group met at 11:00am April 12, 2011 in Kon Tiki room of the Catamaran Resort Hotel in San Diego, California USA. Introductions of members and guests were made. The chair reviewed requirement for quorum and took count of the membership. The group has

4 thirty-one members; a quorum was established. In attendance there were twenty members and sixty-one guests.

There were no patent disclosures.

The minutes of the March 9, 2010 meeting in Houston were approved as written. The minutes of the October 26, 2010 meeting in Toronto were approved with correction that a quorum was not present so no action pending from the meeting could be addressed.

Projects:

TF – Sub-clause 11.2.2e - Addressing scenarios wherein hot-resistant time data unsuitable for fitting to an exponential decay curve: (There was no discussion on this topic.)

Unfinished Business

1. Proposal Circulated from the Fall Meeting modifying sub-clauses 11.2.2 c, d and f for distribution transformers: The results of the previous survey was shown on the screen, opening the floor to comments. Mr. Marcel Fortin commented that the time constant of a winding varies a lot, and is in function of design and construction. The Chair remarked that the intent of the proposed sub-clause 11.2.2d was to have only one method. The group was polled with a majority preferring alternate 2 (11 vs. 1). The Chair will re-circulate the survey to the WG for approval.

• Add to 11.2.2.c - At least one resistance measurement shall be taken on all terminal pairs within a time less than half the coils shortest time constant after shutdown. • Add to 11.2.2d: Alternate 1 - A series of at least 10 resistance measurements shall be made on one terminal pair corresponding to a phase of a winding in less than 10% of the bulk oil time constant. Alternate 2 - At least 10 resistance measurements shall be made on one terminal pair corresponding to a phase of a winding. All resistance data points shall be recorded at no longer than 30 second intervals and no less than 10 second intervals. • 11.2.2f: Modify to agree with timeframe specified in 11.2.2c.

2. Average oil rise in distribution transformers – The group revisited a presentation previously made by Mr. Hasse Nordman for determination whether to form a TF for determination of average liquid temperature in distribution transformers without external oil circulation. Mr. Marcel Fortin made a comment explaining that the higher than expected gradients were related to the height difference between the core & coils, and the top of tank/radiators, anticipating a lot of different design consfigurations. As there were only two persons present having performed the measurements in order to possibly derive a correlation between internal oil temperature and external temperature, the task could not be pursued. The Chair stated that she will poll the attendees in the future to see if the proposal merits re- visiting.

5 3. Comments made by Marcel Fortin in a previous C57.12.90 ballot: Marcel Fortin has proposed a rewrite of 11.1 and 11.1.2.2 with reference to the back to back method. The Chair will send a survey to the group comparing the existing text to the proposed for consideration.

7 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

10.7 Performance Characteristics Subcommittee – Stephen Antosz, Chairman; Ed teNyenhuis, Vice-Chair; Craig Stiegemeier, Secretary

Introduction / Attendance The Performance Characteristics Subcommittee (PCS) met on Wednesday, April 13, 2011 at 3pm with 56 members present at the start of the meeting. Prior to this meeting, the total membership of PCS was 87 members; therefore with 56 present, we did have in excess of 50% of the membership, meeting the requirements for a quorum.

Chairman's Remarks

Administrative Subcommittee Notes a) Upcoming IEEE – PES Meetings • PES General Meeting: July 2011, Detroit, Michigan. • PES General Meeting: July 2012, San Diego, California. • Next Transformer Committee meeting: Fall 2011, October 30Novemeber 3, Boston, MA; Renaissance Boston Waterfront Hotel; hosted by Charles and Mary Ann Sweetser and Omicron USA b) New Program Manager from IEEE for Transformers Committee: • Matt Ceglia has moved on to a new position. His temporary replacement is Erin Spiewak, [email protected], 7324657806.

Git ‘er done A frequent complaint we all have of our IEEE activities is that the work drags on for years and years. I doubt if many people disagree with this. So I want to encourage all PCS WG & TF Chairs (Members, and Guests) to: • Avoid scope creep, by consciously considering why the group is formed, what is our objective, timetable, etc. Take a moment at future meetings to add to the agenda a review of the scope of your WG/TF to make sure you are on track to complete. There are many other good projects in the pipeline that we could move on to. Don’t be afraid to finish. • Promote efficiency by better time management at the meetings and in between meetings. Push a little harder to make group decisions quickly.

General Comments The chair requested that all chairs and coordinators send reports to the PCS officers for incorporation into the meeting minutes.

Approval of Meeting Minutes The minutes of the last meeting in Toronto, Ontario, Canada were approved as written. Working Group (WG) and Task Force (TF) Reports

S11PCSMinutes Page 1 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

10.7.1 WG on Loss Evaluation Guide C57.120 – Don Duckett, Chair; Alan Traut, Vice-Chair PAR Status: PAR Approved PAR expiration Date: 12/31/2014 Current Draft Being Worked On: None The meeting was called to order at 11am on Tuesday April 12, 2011. Attendance of membership was taken. Attendance: 54 total; 18 of 27 Members present, establishing a quorum. 34 Guests, of which 2 requested membership The minutes of the Fall 2010 Toronto meeting were approved as submitted. A request was made for disclosure of any patents that may be related to the work of the WG, and there were no responses to the request for disclosure. The WG began a review of PC57.12.33/D9 which will be used as the basis for the first draft of the revised loss evaluation guide. Clause 4 covers the basic formulae used to calculate the loss evaluation A and B factors for utility users. We decided to include cost of emissions in the capacity and energy cost determinations. We will also include a discussion of the uncertainty in the assumptions used to determine A and B factors and the means to address the uncertainty, ie, Band of Equivalence (BOE) and Monte Carlo simulations. The chair also reported on the Department of Energy (DOE) work on evaluating revised efficiency levels for distribution transformers. This material will be made available to the WG and considered at the next meeting. There was no other new business. The WG adjourned at 12:15 pm and will need a meeting slot at the Fall 2011 Boston meeting.

10.7.2 PCS WG on “Test Code C57.12.90” – Mark Perkins, Chairman; Craig Stiegemeier, Secretary This working group met on Monday, April 11, 2011 at 9:30am in the Kon Tiki Room 1. Kirk Robbins has requested that someone else take over the WG Secretary duties. Craig Stiegemeier agreed to become the WG Secretary. 2. Introduction of members and guests 3. Membership quorum – 44 of 83 members of were in attendance, adequate to qualify the meeting for conducting official business. Membership rosters were circulated. After review and addition of 20 people requesting membership, the Working Group now numbers 103 members, of which 54 attended the meeting. There were also61 guests at the meeting. 4. Patents – no one identified any patent issues. 5. Approval of minutes of the Fall 2010 Meeting in Toronto • Motion and second, minutes approved unanimously 6. Old Business • A suggestion for subtractive and additive polarity in Section 6.1 was reviewed. Steve Antosz provided suggested diagrams presented as Figures 25, which were reviewed with the attendees. No comments were made, and the Chair announced that these figures would be used.

S11PCSMinutes Page 2 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

• Section 6.2, Polarity tests for single phase transformers was reviewed. Ratio meter is listed first as the most common method. The inductive kick and alternating voltage methods were reviewed and included as sections 6.2.2 and 6.2.3, respectively. • The Chair covered Section 6.3, which describes the Polarity and phaserelation test methods for polyphase transformers. Figures 7 and 8 were reviewed and noted unchanged from the current standard. • Section 7, Ratio tests was reviewed. It was noted that outdated methods have been removed and the wording simplified. The voltage and frequency for the ratio test in 7.1.2 was clarified to reflect the use of available power frequency for the ratio test. The wording in section 7.1.3 and 7.1.4 was reviewed. The method for testing transformers with inaccessible neutrals in 7.1.4 and covered in Figure 9 was reviewed and discussed. It was suggested that words be added to the notes in Figure 9 to clearly state which terminals should be shorted. The majority of the members thought adding “short H1H3” and “short H1H2” should be added to the notes in Figure 9. The motion passed 330. • Section 7.3, Ratio test methods (voltmeter and transformer ratio meter) were reviewed. The current standard limits the method to transformers with ratios of 30 or less. Since there was no alternate method for transformers with a ratio greater than 30 and the method works, this limitation has been removed. • The working group made a motion and voted to continue and survey to the PCS Subcommittee with the changes as reviewed today. The motion passed 410. 7. New Business • A question on the status of Clause 12. It has successfully passed a survey and is waiting for total review with the balance of the C57.12.90 document. • The portions of C57.12.90 that fall under PCS are in good condition. Clauses 8 and 9 (no load and load loss/impedance) are possible topics for review at the Fall 2011 meeting in Boston. 8. Motion for and unanimous agreement for adjournment at 10:20am.

10.7.3 PCS TF on Dielectric Frequency Response – George Frimpong, Chairman; Poorvi Patel, Secretary This was the first meeting of this TF; which will review the current existing practices for DFR to see if there is a need to develop a paper, guide, or standard. TF has been challenged to complete its work in 3 meetings or less, and the TF Chair has accepted this timeframe. The TF met on Monday, April 11, 2011. The meeting was called to order by the chair at 3:15 PM. There were a total of 51 attendees; 22 requested membership and 29 guests. 1. Introduction of members and guests 2. The IEEE Patent disclosure requirements were discussed and a request was made for disclosure of any patents that may be related to the work of the TF. a) Mark Perkins indicated that ABB has a patent that may be applicable. The chair will send the requisite form to ABB to secure a Letter of Assurance. 3. The scope of the task force as described by the PCS chair was presented, as follows: a) Review existing practices of Dielectric Frequency Response measurement techniques, to determine:

S11PCSMinutes Page 3 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

• if the technique has technical merit • if the technique is proven and commercially available • if the technique IS (not "can be", but "is" already) a practical useful tool for the industry b) Review the relationship of DFR measurements to existing projects or Standards. (such as Annex G of PC57.152 D4.1) c) Determine whether sufficient interest and resources exist to develop an IEEE tutorial, paper, or guide. d) Prepare a report to the PCS chairman to address these issues, summarize the findings, and make recommendations on a course of action. e) If a further project is suggested, then define the intended Title, Scope, and Purpose for the PAR. f) The TF has 3 meetings to complete its work and present its findings to the PCS chair. There was discussion about the scope but no changes were suggested or made. Mark Perkins indicated that the DFR presentation given at the Lombard meeting in Fall 2009 addresses all three items in item (a) of the scope. The material in that presentation will be incorporated into the task force report. The presentation is available on the transformers committee website. 4. In an effort to speed up the work of the task force, four groups were created to handle various aspects of the scope. These groups will work via teleconferences inbetween scheduled committee meetings. Task Volunteer Assignments

1. Generate a comprehensive bibliography of published George Frimpong materials on theory and application of DFR (scope #1) Sanjib Som Ali Naderian 2.

S11PCSMinutes Page 4 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

5. Charles Sweetser asked that the TF consider not only the successes of the DFR technique, but also the cases where it failed to give a diagnosis. In addition, Steve Antosz implored the TF to consider both the pros and cons of the DFR method. 6. The chair set the following time table for completing the work of the task force: a) Spring 2011 • agree on scope and tasks • task assignments b) Fall 2011 • first drafts/reports of tasks (#1 #4) c) Spring 2012 • final draft review and obtain comments d) After Spring 2012 Meeting • submit report to PCS Chair 7. Since many of the attendees were not present at the DFR tutorial during the Lombard meeting, Jim McBride suggested the tutorial be repeated for their benefit. The highlights of the tutorial were presented by the original presenters. 8. The meeting was adjourned at 4:30 PM.

10.7.4 PCS WG on “General Requirements C57.12.00” – Steve Snyder, Chairman; Enrique Betancourt, Secretary The Working Group met at 3:15 PM on Monday, April11, 2011 with 33 members and 57 guests present. As the current Working Group membership stands at 58 members, we did have a quorum at the meeting. The following (14) guests requested membership, that will become effective only after confirmation of attendance to two (2) consecutive meetings: Alexander Chesnakov Delta Star Javier Arteaga ABB South Boston James Graham Pike Energy David Harris Waukesha Electric David Murray TVA Dwight Parkinson Cooper Power Systems Hakan Sahin ABB Jagdish Bunde Virginia Transformer Jill Smith Bureau of Reclamation Myron Bell Delta Star Raj Ahuja Waukesha Electric Roberto Assano ABB Shankar Nambi Bechtel Stephen Jordan TVA Following introductions, the minutes of the October 25 Toronto meeting were approved. Working Group members were then asked if anyone was aware of any applicable patent activity that might impact our work. No patent issues were disclosed by anyone. The meeting agenda was presented and approved. The meeting began with Old Business , WG item 82 :

S11PCSMinutes Page 5 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

WG Item 82, Clause 7.1.4.4 Stabilizing Windings Addresses an issue raised in an earlier ballot of standard C57.12.00 which requested : (a) Recommendations for guidelines to determine MVA rating of buried tertiary windings, (b) To define the conditions under which this MVA is applicable, and (c) Determine the tests or calculations necessary to prove the tertiary MVA rating. The chairman of the Task Force (Enrique Betancourt) that was formed to address the subject gave the Working Group an update on the status of the TF work. The TF has now agreed to a specific clause for insertion into standard C57.12.00, as follows : 5.11.1.2 Thermal Rating for Stabilizing Windings “In addition to the short circuit duty (see 7.1.4.4), stabilizing windings shall be designed to withstand the transient and continuous thermal duty specified by the user, to allow verification of compliance with maximum allowable temperatures according to the present standard. In the event no continuous thermal duty for the stabilizing winding can be established from the user’s specification, the manufacturer shall design the stabilizing winding considering the circulating current in that winding, resulting from a full single phase load in the largest main secondary winding (for more than one secondary winding). The manufacturer is to determine the stabilizing winding MVA rating based on the transformer’s or autotransformer´s equivalent circuit for single phase loading condition. The manufacturer is to calculate values of hotspot and average temperatures for the stabilizing winding to verify compliance with allowable temperatures. Initial conditions for those calculations will be considered as the transformer or autotransformer operating at its maximum continuous rating, before switching to the loading conditions described in the first or second paragraph of this clause, whichever applicable.” This new clause on thermal performance of stabilizing windings will be sent for a survey within the Performance Characteristics and Insulation Life Subcommittees. Once accepted, the work of this task force will be completed. However, there has been strong interest among the attendees at these meetings to continue working on the general topic of tertiary and stabilizing windings. A showofhands among the task force attendees showed 28 individuals interested in participating in the development of an Application Guide for Tertiary and Stabilizing Windings. A Title, Scope and Purpose have already been developed, and were presented to the task force meeting attendees and found adequate to start the process of a new Working Group, if approved.

WG Item 87, Table 18 Short-circuit apparent power of the system This item is based on a comment (negative ballot from 2006) that the system short circuit current levels listed in Table 18 are unrealistically high, leading to designs that may be uneconomical. The suggestion was to limit these assumed fault current levels to 63 kA and lower. A task force to focus on this topic, chaired by Bruce Forsyth, was formed at the Toronto meeting. Bruce reported at this meeting that the TF held a webbased meeting on February 24 for the purpose of reviewing and, if necessary, updating the values in Table 18 to ensure they are reasonable given current industry practice. The TF also planned to hold an off schedule meeting on April 12 to review action items from the February 24th meeting and to consider any further action required.

S11PCSMinutes Page 6 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

WG Item 92, Add to Nameplate, Oil Volumes from 25C and 65C to Low Alarm A request was received from the 2009 ballot of standard C57.12.00 to change the nameplate information concerning liquid volumes. The comment was that there is an interest in knowing how much oil would be spilled before the liquid level gauge would reach the low level and alarm. Suggest adding liquid level volumes from 25°C and 65°C levels to low oil alarm. Since the previous meeting, the chairman of the WG contacted M. Thaden, who explained that the information is useful, but not critical. The floor was open for discussion or further comments, with no support for adding this information. The subject was dropped and this item is considered closed.

WG Item 89, Reference Temperature in C57.12.00/D2C –/2008 Sections 5.9, 7.4, 8.4, 8.7 Requested Change : The term “reference temperature” appears eight times with five different definitions (in standard C57.12.00). The request is to define the two terms “Core Reference Temperature” and “Reference Temperature” in C57.12.80 and then modify the standards which refer to those definitions accordingly. For C57.12.00 it would be the sections cited above. Section 5.9, Total Losses , suggested change accepted by the WG : “The standard reference temperature for the load losses of power and distribution transformers shall be defined as 20 ºC plus the rated average winding rise.” Section 7.4 (calculation of winding temperatures during short circuit) , no changes deemed necessary. Present statement is “Tr is the reference temperature defined as 20ºC ambient plus the rated average winding rise.” Section 8.4 (determination of transformer regulation) , suggested change accepted by the WG : “Regulation calculations shall be based on a reference temperature defined as 20ºC plus the rated average winding rise.” Section 8.7 (certified test data) , note 3, suggested change accepted by the WG : “All temperature sensitive data shall be reported after correcting to the reference temperature as defined by IEEE Std. C57.12.80 and section 5.9 of this standard.” The Working Group then began discussions on New Business , as follows :

WG Item 93, C57.12.00 -2010 Section 4.3.3 Other unusual service conditions, note q) Requested Change: Parallel operation is quite a common practice. Review the clause by saying that this is a normal practice and that the user shall advise the manufacturer if this is effectively the case. After reviewing and discussing the existing clause, the WG determined it to be accurate as is, so no changes will be made.

WG Item 95, C57.12.00 - 2010 Section 5.1, Table 2, Cooling class designation Requested Change : This data has been in the last two revisions and should not be needed in the main body any longer. Move lines 7, 8, 9 and Table 2 to the annex. After discussing the request, with 27 members in favor and two opposed, the Working Group decided to move Table 2 to the annex, with appropriate wording in the main body of the standard referring to that annex.

S11PCSMinutes Page 7 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

WG Item 95, C57.12.00-2010, Section 5.5.3 Ratings of transformer taps Requested Change : Change the definition of reduced capacity to match C57.12.10. The Working Group reviewed the clauses from both C57.12.10 and C57.12.00. As part of the discussion, it was pointed out that in both documents it is implicit that the reduced capacity onload taps would be located only on the LV side. After a lengthy discussion, the WG made the decision to leave the text in C57.12.00 as it is, with 28 members in favor and none opposed. The meeting was adjourned at 4:30 PM.

10.7.5 WG on “IEEE Standard Requirements, Terminology, and Test Procedures for Neutral Grounding Devices”, PC57.32 – Steve Schappell, Chairman; Peter Balma, Vice-Chair The Neutral Grounding Devices working group was called to order at 8:00 AM on April 12, 2011. There were 31 attendees: 13 members and 13 guests, with 1 requesting membership. Copies of the previous meeting minutes were distributed. The WG is up against a wall. The Std expires at the end of this year AND the WG’s PAR expires at the end of the year. The WG is on a fast track to get the document out for ballot within the next couple months, and the people in attendance responded in kind with acceptance of several volunteer assignments. 1. Introductions were made, and the IEEE patent policy was reviewed. The group was asked if there were any patent disclosures, none were indicated. 2. The agenda for the meeting was reviewed and it was determined that a quorum was present. The committee roster has been reviewed to maintain the voting member list, and it was indicated that the working group chair should be contacted for any concerns relative to membership. 3. The minutes from the Toronto, Canada meeting on October 26, 2011, were approved without comment. 4. The PAR for the working group is valid until the end of 2011; therefore, it is critical for the standard to be balloted as soon as possible. 5. The Performance Characteristics Subcommittee Chair, Stephen Antosz, joined the meeting and encouraged the working group to get this standard into the balloting process. Further, he offered to assist the group in any way he can, and he stressed that the PAR would expire at the end of the year. 6. The working group then proceeded to review comments and input received from working group members and guests since the last meeting. • It was suggested to add an additional clause or paragraph to the reactor section of the document to provide information on the application of grounding reactors when located on the cover of transformer tanks. The working group agreed. • It was then pointed out that the terms grounding transformer and neutral grounding transformer were both used in the standard, but were not clearly defined and differentiated. The working group accepted that this should be reviewed, and recommended that a reference to C57.12.80 may help to clarify the terms. • Several questions on test values for dielectric testing, as well as low frequency tests for grounding transformers were discussed. The section of the standard applying to transformers is still being revised, and the group concurred that the information was

S11PCSMinutes Page 8 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

needed and will be included. This topic was revisited later in the meeting, where it was decided that the test values would be provided for dry type transformers up to 34.5 kV, and for oil filled transformers up to 230 kV. It was also decided that multiple BIL levels for a given system voltage would be included as is done in C57.12.00. Devki Sharma agreed to construct a table for these transformers. • Next, the coefficient of resistivity for grounding resistors was reviewed. (Peter Balma, vice chair, recused himself from the vice chair position for this portion of the meeting, to join the discussion as a working group member). This topic and background information from other related standards (UL1676, TILD31, and PIPELSGS11) was presented. In addition, consideration was given to suggesting limits and or guidance on the coefficient of resistivity. It was suggested that it would be beneficial to have some information on this topic for users of the standard, and that perhaps an informative annex could be added for this purpose. Sergio Panetta agreed to revise the resistor section, and to consider an informative annex. 7. The working group then reviewed the remaining areas of the draft to be completed. • Definition 3.6 is focused on reactors and does not apply for all devices, and needs to be revised. Peter Balma and Richard Dudley volunteered to do this. • A final check has to be made that all 4second ratings references have been removed from the document. • Table 9 and 10 (Draft 9) provide guidance on the limiting temperatures for current carrying parts of neutral grounding devices. After discussion of these by the group, it was decided that these tables would be revised to reflect transformers only and would be based on 55°C rise as in the original document. Sheldon Kennedy agreed to revise the tables. • The text of Clause 8, Tests, has to be reviewed for consistency with the remainder of the document. The clause was originally structured around a common dielectric test table; however, this table has now been split into sections within the clause for each type of neutral grounding device. • It was agreed that the dielectric test values for combination devices should be based on the values of the component with the highest requirements. The clause will be revised to reflect this. 8. All members of the group were requested to provide their input as soon as possible, but no later than 3 to 4 weeks from the date of this meeting. 9. The plan is hold web conferences once a week to assemble and review all the input and changes required. Volunteers for the calls were requested, but it was decided to send the emeeting notices to all members and those in attendance at this meeting. The meeting adjourned at 9:17 am.

10.7.6 TF on “Semi–Conductor Rectifier Transformers”, C57.18.10 – Sheldon P. Kennedy, Chairman The Working Group met on Tuesday, April 12, 2011 at 3:15 PM with 10 members and 2 guests present. There were 4 new members added to the Task Force. Sheldon Kennedy chaired the meeting. We did not have a quorum. The IEEE disclosure statement was discussed. There were no patents pertaining to this standards work for which any members had awareness, although, we did discuss the

S11PCSMinutes Page 9 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

previously noted patents on phase shifted windings. We had already decided to avoid showing any particular winding arrangements for mulitpulse transformers. The minutes of the October 26, 2010 meeting in Toronto, Ontario were read but could not be approved due to the lack of a quorum. The chair made a proposal for a clause on electrostatic ground shields. The Task Force proceeded to make revisions to the discussion of the electrostatic ground shield. Information was added to require it to be shown on the nameplate if it is included in the design. Also, notes about possibly higher insulation power factor test values and dielectric frequency response test values were also added. Phase shifted secondary windings with multipulse secondary windings such as 18 pulse, 24 pulse, 36 pulse, 48 pulse and 54 pulse are becoming a great part of the motor drive transformer applications, as well as higher current rectifier transformers. There is no discussion about these in the present C57.18.10 and this will need some work. We began to discuss how we would incorporate these circuits into C57.18.10 since this is all relatively new work since the document was originally published in 1998. Numerating additional rectifier and transformer circuits was discussed. At our meeting in Lombard, Dhiru Patel informed us that there were patents on a lot of the methods of phase shifting windings by the drive and rectifier companies. Not wishing to have a problem with patents, the Task Force decided to just propose general discussions of phase shifting windings and not give any of the exact phase shifts that are being used in industry. This seemed the best way to accomplish this. The Chair submitted a proposal of a general discussion of the topic for the Task Force to consider. It was well received but could use some additional comments by members. Members will give comments to the chair by the next meeting. There was a discussion about the standards being written in the Vehicular Transportation Society of IEEE. A traction rectifier transformer standard, rectifier standard and many C37 switchgear standards are being revised by this organization with emphasis on the needs of the transit and rail industry. Concerns about duplication of standards and conflicts in the standards were raised. This standard has been reintroduced and a balloting group was being formed. The chair announced that the IEC Converter Transformers for Industrial Applications IEC 613781 standard is under revision again. The chair discussed some of the highlights of their latest draft. This has now proceeded to an FDIS in IEC. We will ask IEEE to request a copy of their work for harmonization with our document. To date, I have not been able to get approval to share the information. The Chair will again discuss this with IEEE staff and may be able to get this before the next meeting. The Task Force will look at the tables of circuits at the next meeting and discuss how we might go about revising these according to the new IEEE format. There were no further comments. The meeting ended at 4:30 PM.

10.7.7 TF on “Audible Sound Revision to Clause 13”, C57.12.90 – Ramsis Girgis, Chairman The TF met at 11:00 am on Monday, April 11, 2011 with a total of 83 in attendance, 19 members and 64 guests, 5 guests requested membership of the TF. This is a record attendance for this TF; which is very encouraging. This will allow a greater exposure of members of the Standards committee to the workings of this TF; which should help in the process of balloting the revised Clause 13 of C57.12.90.

S11PCSMinutes Page 10 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

First, the minutes of the Toronto meeting were approved as written. The chairman then announced that this was the first meeting of the TF under the PCS SC. For a number of meetings, this TF was under the ASV SC. He also informed that the Noise measurement Standard in IEEE C57.12.90 and the IEC 60076 – 10 Standard are presently being revised in parallel. Every effort is being made by the chairmen of this TF and the IEC WG to harmonize the two Standards. The 1st item discussed was the appropriate conditions for accurate measurement of transformer noise using the “Sound Intensity Method”. The chairman reported that the IEC WG included in its most recent draft conditions that are mathematically equivalent to those which the IEEE TF suggested and agreed to. However, the chairman suggested that the correction should conceptually be applied to the measured Intensity level not the Pressure level. The chairman will resolve this item with the chairman of the IEC WG. The 2nd item discussed was measuring Load Noise. The TF previously agreed to include in C57.12.90 Load Noise testing upon customer’s request and not use the condition stated in the IEC Standard for measuring Load Noise because of the inaccuracy associated with the formula used in the Standard to calculate Load Noise. In spite of bringing this up to the attention of the IEC WG, the latest draft of the IEC Standard still includes that condition. The chair will try again to convince the IEC WG of the inadequacy of using that condition. Next item discussed was the correction for sound wall reflections. The IEEE TF has decided to introduce this correction to the “Sound Pressure Method” but limit its value to 4 dB. The latest draft of the IEC Standard still includes a limit of 7 dB but added a note that if the correction is > 4.1 dB, the correction would need to be determined by measurements. Next item discussed was the wall Absorption coefficient. The IEEE TF has suggested using only 3 or 4 values instead of the 7 values used in the present IEC Standard. Data demonstrated that the magnitude of error associated with this simplification is only a fraction of a dB. The latest draft of the IEC Standard includes 5 values with different definitions of the environment corresponding to these values. The chairman of this TF intends to work out an agreement with the chairman of the IEC WG on optimum values of this coefficient and definitions that are more descriptive of the environment of the test area. Next item discussed was the sound measuring contour. Originally, the IEEE TF suggested a 1 m contour all around in order to minimize the near – field effect as well as the contribution of ambient noise. The latest draft of the IEC Standard includes a 1/3 m contour for distribution size transformers and 2 m uniform contour as a standard, except in cases of test room dimension limitations or low signal – to – noise ratio in case of low noise transformers or high background noise. This will apply whether it is ONAN or ONAF. The IEEE TF will keep the 1/3 m contour for ONAN. For ONAF, the TF voted to use a uniform 2 m contour whenever noise testing is performed with the cooling equipment running. This will replace the present practice of having the contour at 2 m from the fans when they are running and 1/3 m for the rest of the transformer surface. The last item discussed was the calculation of the sound radiating surface area used to calculate sound power. The IEEE Standard equation has a 1.25 multiplier of the vertical sound radiating surface. This multiplier accounts for the sound radiating from the transformer cover. The latest draft of the IEC Standard has an equation where the distance between the measuring contour and the transformer; whether it is 1/3 m or 2 m, is added to the height of the transformer. For a medium size transformer of about 3 m height, when measuring the ONAF noise level, the IEC calculation translates into a 1.66 multiplier instead of the 1.25 IEEE multiplier; resulting in a 1.2 dB high sound power level. Since the IEEE

S11PCSMinutes Page 11 of 13 Performance Characteristics Subcommittee Unapproved Meeting Minutes – San Diego, California – April 13, 2011

equation is more representative of the physics of the sound radiation and sound measurement, the IEEE TF will keep the equation used presently in C57.12.90. The plan is to present a first Draft of revised Clause 13 of C57.12.90 at the Boston meeting. Subsequent to the meeting, Barry Beaster offered to serve as the Secretary of the TF. The Chair thanks him for his offer.

10.7.8 TF on Transformers Directly Connected to Wind Turbines – David Buckmaster, Chairman; Vice Chair: Phil Hopkinson; Secretary: Scott Choinski The Task Force on Wind Power Transformers was called to order at 9:30 AM on April 12. There were 106 attendees, 23 members, 83 guests with 19 requesting membership. A survey of members present was conducted and showed18 members were present, which is not a quorum. Another survey was conducted which showed 8 requested membership at the last meeting and would become members after this meeting. There were no patents to disclose. The minutes from the meeting held October 26, 2010, was accepted as written. 1. Announcement for transition to a Working Group This TF has been moved to the Performance Characteristics SC. The TF will disband and become a WG at the fall meeting. Membership on the WG would be reset to those attending the first meeting. Membership requirements would be to attend 1 meeting per year, and missing 2 meetings in a row is grounds for removal as a member. Chair can exercise discretion in granting waivers for certain circumstances. This group was designated as a TF to explore developing a PAR, and all attending the meeting were granted membership. 2. Status of IEC 6007616 The IEC WG met in late November to review document and consider the IEEE comments submitted. The document has not yet been circulated as FDIS yet and is expected at any time. 3. Discussion to develop PAR Motion: Make the document a standard Approved with none opposed The TF approved the following Title: Standard requirements for Wind Turbine Generator Transformers [DEB – Corrected 04/13/11] The TF approved the following Scope: This standard establishes requirements for Liquid Immersed, or Dry Type transformers with at least one set of terminals rated ≤ 38 kV with a capacity rating ≤ 100000kVA suitable for StepUp operation to be used to transform the voltage from the Wind Turbine generator to the system voltage of the collector grid. The TF approved the following Purpose The purpose of this standard is to enable manufacturers and users in specifying, designing, and manufacturing transformers used for Wind Turbine Generator duty. 4. New Business None

10.7.9 WG - Status of PC57.142, “Switching Transients Induced by Transformer / Breaker Interaction”, – Robert Degeneff, Chairman; Bill Griesacker, Secretary Status report presented by Stephen Antosz 1. There was no meeting of the working group this session. 2. Draft 8.3 of the guide was recirculated a sixth time between October 12 and October 22, 2010. There were 154 eligible voters. 143 voted with 129 voting affirmative, 3 negative, and 11 abstentions. 3 comments were received. This was a 98% affirmative vote. Two of the comments were editorial and the third was of a general nature that could not be addressed in this ballot cycle. 3. Draft 8.3 of the guide was submitted RevCom for its December meeting and was approved for publication. 4. The Chairman has been unofficially told that C57.142 will be sent out this week for proof reading of the final copy. The Chairman will contact a number of working group members to assist in this proof reading effort. Publication should follow by early fall.

10.7.10 Status update of “Guide for the Application and Interpretation of Frequency Response Analysis for Oil Immersed Transformers”, PC57.149 – Chairman; Charles Sweetser The PAR has been revised and extended. Mandatory Editorial Coordination is complete. The ballot pool is being formed. The ballot should be opened in the next month or so..

10.7.11 Old Unfinished Business None

10.7.12 New Business Phil Hopkinson suggested that the work of the PC57.142 group as reported in 10.7.9 above be continued for higher voltage applications. The motion as proposed and seconded was to form a task force to address high frequency transient over voltages higher than medium voltages; involving bushings, transformer windings, and interactions with the system, including backfeed operation of generator step up transformers. Significant discussion ensued and the motion passed by a vote of 29 to 9. The exact plan of implementation was not decided and requires careful consideration to make sure we get it right. The chair requested that a written detail of this proposal be provided by Phil to circulate amongst the Administrative Subcommittee for discussion and use as the basis for defining the scope and direction of a new Task Force. It was noted that this effort would require significant coordination with other transformer committee groups as well as others with broader system implications.

Meeting adjourned at 4:15pm

10.8.1.2 WORKING GROUP FOR DEVELOPMENT OF PC57.143, GUIDE FOR APPLICATION OF MONITORING TO LIQUID IMMERSED TRANSFORMERS AND COMPONENTS – Donald Chu and Andre Lux, Co-Chairmen

Tony Pink reported that the WG did not meet. The Guide has been balloted and is currently in ballot resolution.

10.8.1.3WORKING GROUP FOR DEVELOPMENT OF PC57.148, STANDARD FOR CONTROL CABINETS FOR TRANSFORMERS – Joe Watson, Chairman

Joe Watson reported that the WG did not meet. The document was balloted shortly before the Toronto meeting and one recirculation was issued and received. There are only a few issues that need further revision to address all of the comments and a 2nd recirculation should be issued for balloting on these changes in late April or early May

10.8.1.4WORKING GROUP FOR DEVELOPMENT OF PC57.131, STANDARD REQUIREMENTS FOR TAP CHANGERS - William Henning, Chairman William Henning reported that the Working Group on Tap Changer Performance met on Monday, April 11, 2011 at 1:45 pm with 12 members and 32 guests present. There were introductions and a call for patents. A quorum was present, and the minutes were approved.

The main subject for discussion was the recirculation of Draft 1.6 of C57.131. The recirculation opened on April 8 and closes on April 28. The working group chairman gave a report on the recirculation. Part of this was to read from a list of all the changes made since the initial ballot. This was done to give the entire working group, and the guests present, an idea of the nature of the changes.

At a time prior to the working group meeting, a balloter pointed out that the posted copy of the draft does not, itself, show the changes. The balloter requested that change tracking be added to the document to make it easier to know the changes.

This subject was discussed at the working group meeting. The possibility of posting a list of changes, instead of modifying the document, was also discussed. No strong conclusions were reached in these discussions.

The meeting was adjourned at 2:40 pm.

After the working group meeting, the chairman discussed this subject with the IEEE liaison for the project. She indicated that one option is to upload a red-lined copy of Draft 1.6 and extend the closing date.

On April 20, 2011, a red-lined copy was uploaded. At the same time, the closing date was extended to May 8, 2011.

10.8.1.5 WORKING GROUP FOR DEVELOPMENT OF PC57.150, GUIDE FOR THE TRANSPORTATION OF TRANSFORMERS AND REACTORS RATED 10,000 KVA OR LARGER –Greg Anderson, Chairman

Basic paralleling information  General applications – system configuration o Distribution o Network intertie o Distribution substations with generation  Reasons for parallel operation  Basic tap changer control - voltage control  Consequences of improper paralleling  Transformer requirements for parallel operation 5. Requirements of the Paralleling Control System  Basic responsibility of the control system o Maintain the same tap position (transformer turns ratio) of all paralleled transformers o Minimize the current difference between transformers o Minimize the reactive current difference between transformers o Equalize the paralleled transformers load power factors.  System configuration

Comments and proposed changes received in written format prior to the meeting were reviewed:  The chair gave a brief presentation on circulating current using an example of two transformers with the low side breaker closed and the high side breaker in both the open and closed position.  Proposal was made to add a definition of circulating current - Karsten Viereck (Reinhausen) to prepare  Proposal was made to add a paragraph to the power factor method section – Karsten Viereck to provide this additional information in 3 weeks.  Steven Anthony – Pepco Holdings volunteered to review and modify the drawings in the guide document to ensure all sections use a similar look  Several members commented the document should reference C57.12.80 for definitions of the acronyms used in the document.  The working group felt the language to describe the section on LDC-Z needed to be revised. Steve Averitt – Reinhausen Mfg volunteered to write an alternative paragraph  Motion was made and accepted to change the following wording:

Present text - This paralleling guide describes and compares control methods and operations of paralleled power transformers equipped with load tap changers (LTC) or series regulators. Proposed text - This paralleling guide describes and compares control methods and operations of paralleled power transformers with load tap changers (LTC) or step voltage regulators. Vote taken – motion passed.  Group was reminded that our PAR expires in 2012 and we still have a lot of work to do.

A motion to adjourn was approved and the meeting adjourned at16:25 p.m.

10.8.1.11 TASK FORCE FOR TRANSFORMER TANK RUPTURE AND MITIGATION – Peter Zhao, Chairman

Meeting of the Task Force for Tank Rupture & Mitigation convened Monday morning at 11:00am. Chairman Peter Zhao presided.

The Patent policy was displayed and discussed. There were no acknowledgements of patents of concern.

Attendance was 102 (17 members, 85 guests, with 8 guests requesting membership). Chairman Zhao provided introductory remarks and previewed the agenda to be covered for the meeting.

The PAR for the guide has been approved by Ad Com and now will be sent to IEEE for final approval. The objective of the meeting was to make progress on the document in anticipation of PAR approval.

Sections 4.3.1 and 4.3.2 recent additions were reviewed. Don Chu questioned the basis for the numbers provided for arc voltage and arc energy, and stated that Owner should only be responsible for providing available fault levels and voltages. Martin Heathcoat stated a significant value of the guide will be as a tool by which design reviews can verify adequacy of manufactures design for withstanding internal faults without rupture. The fact that relevant numbers are hard to derive is all the more reason that the Guide is needed to provide a rational basis for assuring adequate design.

It was suggested that the Guide be segmented: Most of section 4.3, since it is tutorial in nature, should be moved to an annex, to be referenced in the main body of the guide. Don Chu predicted that a draft of the guide that includes such numbers as presently included in the main body of the document will draw strong negative opinion/ballots. Izyaslav Polishchuk of Hydro One expressed a need for retaining the numbers as charts referenced in an annex.

Several Users agreed that numbers should reflect an assumption that first level breaker protection/isolation fails, taking more time for secondary breakers to operate. Also that a method of deriving relevant numbers must be included in the guide. Don Chu suggested issuing the document as a ‘trial use guide’, with methodology and equations for deriving results. Dependence should be on formulas, and not tables, which should remain as examples of what others have derived for particular cases. In regard to the new chart addition to 4.3.4, Martin Heathcoat explained that the unpopulated chart was included to hold the spot for numbers he expects to obtain before the next meeting.

Isy Polishchuk indicated that Hydro One derived a chart many years ago, and has recently revised the numbers. 40% margin included in section 4.3.9 was questioned. Bill Darovny indicated that margins should not be included in this document and that it is the business of manufacturers to add margins according to their own criteria. Practicality of manufacture’s testing to validate the adequacy of design was discussed and the consensus was that destructive tests for a power transformer of any significant size would be impractical and cost prohibitive. Martin Heathcoat suggested that such a test on a larger transformer may be equated to short-circuit testing. Paulo Avelino of Siemens suggested that a model should be established - then verified by testing. Tom Lunquist inquired as to whether Hydro One has done such a test. The answer is that actual testing has been done only on distribution class transformers.

The meeting was adjourned at 12:15p.m.

10.8.1.12 TASK FORCE FOR DVP-GRID TRANSFORMERS – Hemchandra Shertukde, Chairman

Hemchandra Shertukde reported that the Task Force met in the Boardroom of the Catamaran Resort Hotel. The meeting was called to order at 11:00 a.m.

The meeting was convened with 12 members (out of current 23 members) and 23 guests present. The TF did have a quorum.

The IEEE patent recommendations were addressed, no patents or patent claims were identified in relation to the work of TF.

Old Business Toronto’s meeting minutes were approved.

New business. TF discussed the draft of TF’s Position Paper.

- Title of the position paper was revised and it is “Consideration for transformers applied in Distributed Photo-Voltaic (DPV) Grid application”. - Introduction  It was confirmed that the residential and industrial type photo-voltaic systems are covered with this Position Paper.  Position Paper covered single-phase and 3-phase units. - Existing Standards and areas of differentiation of DPV-GT.  Position Paper summarizes the input of the TF members on the reviewed existing standards in order to identify how the problems, perceived for DPV GT, are covered with the exiting standards and identify areas of differentiation.

 This summary was reviewed. Some DPV GT differentiation points were discussed: - LTC in case of an inverse power flow – additional note added to the Position Paper highlighting this aspect of the application. - Harmonics – the consensus of the TF was that, generally, the high harmonic level is not expected in this application, but this aspect shall be specifically reviewed at the specification stage.

- Than TF moved to review the Power Subcommittee assignment to Task Force one more time.  The TF consensus was that the Position Paper shall be presented to the PT SC with proposal that work be continued and WG is formed.  The opinion split on whether the TF would recommend the proposed WG to work towards Standard or User’s Guide.  After short discussion, the motion was proposed by D. Ayers and seconded to support establishing of the WG working on the Standard. The chairman conducted the vote to gauge the TF opinion and the motion passed.  Then TF returned to the discussion with PT SC chairman Tom Lundquist emphasized that TF shall yet to come up with the convincing evidence that the Standard on DPH GT is indeed necessary.  The arguments for the Standard included: the guide may contain the optional recommendations which, sometimes, confusing for the users; DPV GTs have special winding configurations; residential use PH GT may require addressing specific safety issues, etc.  The arguments for the Guide included: in contrast to the transformers for wind power generation, the solar generation farms are usually better protected and less accessible to public, which resulted in less specific protection requirements; the inverter between generation and step-up transformer may solve the protection and regulation issues; transformer may often be a part of the inverter package, etc.  TF decided that the Chairman will circulate the TF survey on whether a standard or a guide is the preferable direction to continue the work. After that the decision shall be taken on what recommendation TF provides to the PT SC. One more meeting of Task Force is planned in Fall 2011 in Boston.

With no further business, the meeting was adjourned at 12:15 am. 10.8.1.13 WG for Revision of C57.125 Guide for Failure Investigation, Documentation, Analysis and Reporting for Power Transformers and Shunt Reactors - Wallace Binder, Chairman

The chairman reviewed the patent legal issue and asked whether there were any patents or patents pending that would affect the WG or standard. None were identified. 3. The minutes of the October 25, 2010 meeting in Toronto, Canada were reviewed and approved. Carl Niemann made a motion to approve the Meeting Minutes and Ed Bertolini seconded the motion and they were approved. 4. The meeting consisted of the review of the comments received from the balloting process as of Friday, April 8, 2011. There was an extensive discussion on the balloting process and the fact that some members were not able to cast a vote because of some unknown IEEE rules that prevented individuals from casting a ballot. 5. The chairman suggested that the working group would be the ballot resolution body to resolve the balloting comments. This motion was voted on and approved. 6. The remaining of the meeting focused on the review and resolution of the following balloting comments: A. Comment 1: Add a comma to the voltage value (34 400) shown in the purpose. Resolution: Comment not incorporated. The value as noted is consistent with the way this voltage value is shown on other IEEE standards. B. Comment 2: Add a space to the voltage value (13200) shown in the Rating column of Table 2. Resolution: Comment will be incorporated. C. Comment 3: Normative reference C57.91 is not cited in text so either cite it or move to Bibliography. Resolution: The chairman will take comment under review and will resolve. D. Comment 4: Section 5.6.1 Resolution: Leave section as is. Comment will not be incorporated. E. Comment 5: Section 5.5.5.5 - Remove the word: “level” from the last sentence of this section.

10.10.4 Working Group (WG) and Task Force (TF) Reports

10.10.4.1 WG - Revision of C57.19.00 - Keith Ellis, Chair Reaffirmed C57.19.00-2004 – New expiration date is Dec. 31, 2015

10.10.4.2 WG - Revision of C57.19.01 – Arturo Del Rio, Chair

The WG for the revision of C57.19.01 Standard Requirements for Bushings met on Tuesday April 12th, 2011, at 9:30 am with 36 guests. Since this was the first meeting membership is yet to be established.

The meeting was opened with a request for patent disclosures and introductions. Since this was the first meeting for the WG, there were no minutes from previous meetings. Regarding the scope of this Standard, a modification will be needed in order to avoid conflict with the work being done on the standardization of GSU bushings for use in bus- enclosures. This item will be included in the agenda for the next meeting.

1 The first item in the agenda was the review of the work done during the 2000 revision and 2005 re-affirmation of this Standard in terms of survey and ballot results. After the review of this background information, an open discussion took place with the participation of users, transformer manufactures and bushing manufacturers in attendance. A request was made by the Chair for participants to e-mail comments and suggestions for changes to the existing Standard to [email protected]. Meeting was adjourned at 10:30 am. Any members of the Bushings Subcommittee are welcome to join this new WG and participate in the revision of the Standard.

10.10.4.3 WG - Revision of C57.19.100 – Tommy Spitzer, Chair

No report, ready for ballot

10.10.4.4 TF – GSU Bushings – Catherine Hurley, Chair

April 12, 2011, 1:45pm - Toucan Room at the Catamaran Resort / San Diego, California

1. Attendance : The meeting consisted of 36 attendees: 16 of 22 “members” (quorum was reached) and 20 “guests”, 11 of which were NEW “guests”. 1 “member” requested change to “guest” status. 2 “guests” who have attended previous meetings requested membership, but neither had an attendance record which justified membership. Their request for membership was denied. 1 NEW “guest” requested membership, but membership was not granted because this was his first meeting. The new membership total is 21.

2. Agenda : • No known patent related issues were brought to the attention of the TF • Meeting minutes from Fall 2010 meeting were presented and approved • Status of PAR submittal was discussed. Original submittal rec’d negative votes so the PAR was revised to distinguish this standard from C57.19.01 by limiting our focus to only those bushings rated >5000A and applied in metal enclosed bus, typical of the LV side of GSU transformers. No negative comments have been received to date by the committee and we expect PAR approval and creation of WG by next meeting. • Sections 3 and 4 of the standard, prepared by John Graham, were presented to the members for the first time, and those sections were briefly reviewed and discussed openly. These sections will be distributed to the members by C. Hurley for a more detailed evaluation at the next meeting in Boston. • Dimensional recommendations by European bushing manufacturer Areva/Alstom/Passoni Villa were presented to the group for discussion. Their recommendations will also be distributed to the members by C. Hurley.

3. Adjournment : The meeting was adjourned at 3:10pm

2 10.10.4.5 C57.19.03 – DC Bushing Standard – Les Recksiedler (IEEE) and John Graham (IEC), Chair

IEC62199 “Bushings for DC Application” SC36A MT5 is working with The IEEE Bushing subcommittee with a joint working group to produce a dual logo document. Three meetings have been held, in Lombard (Fall 2009), Houston (Spring 2010) and Toronto (Fall 2010). Work has proceeded by email to avoid a meeting in Europe. A fifth draft has been circulated for comment and any comments would be welcomed. Draft 5 needs the addition of a second annex concerning an alternative method for the calculation of a harmonic equivalent current; this is being prepared by Italy. No meeting will be held in San Diego pending completion of the Annex and official circulation for comment. It is hoped to be able to go for voting at this stage.

The main items to review are; - Creepage distance calculation – specification of the appropriate voltage. - Emission test - Temperature rise test – agreement on method for calculation of the equivalent current. - Dry lightning impulse test.

10.10.4.6 IEC Bushing Standards Activity - John Graham

IEC Meetings The IEC bushing committee SC36A has not met since the IEC General Session in Sao Paulo, Brazil during the week of November 17th 2008. The next meeting is planned for October 2011 in Melbourne, Australia.

IEC60137 “Insulated Bushings for Alternating Voltages above 1000V” Edition 6 was published in July 2008; the maintenance date for IEC60137 is set at 2011. The Chairman recently asked for revision work to be started with a short date of May 20th 2011 for a Committee Draft (CD). The main purpose is to include test values for UHV bushings (above 800kV rating) in line with the latest edition of IEC60071-1: Insulation Co-ordination. During the revision the working group should address inconsistencies in the test method for temperature rise of external connections – this inconsistency also exists in IEEE C57.19.00. Also changes to the calculation of creepage distance in line with IEC60815 will be included. It is hoped that the CD can be circulated and comments prepared for the IEC meeting in October.

10.10.4.8 Task Force on PD Measurement on Bushings & CTs - Thang Hochanh, Chair

MINUTES OF TASK FORCE MEETING – S11 San Diego, CA.

The task force on Partial Discharge in Bushings and PTs/CTs met on Monday April 11th, 2011, at 3:15pm with 45 attendees. Of those, 10 members and 35 guests with 7 guests requesting membership.

The meeting was opened with a request for patent disclosures and introductions. The minutes for the F10 Toronto meeting were presented. The next item in the agenda was a presentation by Alex Kraetge: De-noising and pulse separation approaches based on synchronous multi-terminal frequency measurements. A request was made to have all the presentations delivered to date in the TF meetings posted on the Transformer Committee webpage; the request was accepted since the material is considered public domain. After the presentation by Mr Kraetge, the TF Chair presented a preliminary scope and a proposed outline for the guide. Among the comments to the preliminary scope presented by the Chair were: • The scope limits the guide to wide band detection, whereas narrow band could also be suitable considering the simpler propagation patterns found in the equipment under test. • Both wide band and narrow band detection are presently being used in laboratory settings by manufacturers. • The scope should be limited to laboratory settings for now and consider field PD measurements for future work. • The scope needs to be re-worded to address the above comments. Regarding the proposed outline, the following comments were made: • What instrumentation is appropriate for PD testing needs to be addressed. • The proposed outline includes a separate sections for CTs, PTs and bushings. Is it really necessary as CTs and bushings are very similar regarding PD testing? • Most of the material that it is currently part of the annexes such as calibration, test procedures and PD pattern recognition should be moved to the main body of the guide and decide later if an annex is needed for additional information. TF Chair Thang Hochanh requested volunteers to start drafting the different sections of the guide. Additional volunteers willing to contribute to the guide can contact Mr. Hochang: • W. Hauschild offered to work on the section regarding shielding. • R. Krump offered to work on the section regarding bushings and single ended method. • B. Wimberly offered to work on the instrument transformer section. Meeting was adjourned at 4:15 pm.

10.10.5 Old Business

10.10.5.1 Busing Service Conditions - Devki Sharma

The question was raised by Devki if the external bare bushing terminal temperature of 70C should be changed to meet the value of disconnect switches which allow 90C. Having these value different causes misapplication. He also mentioned that he had tried to get the substation committee to address the issue but was rejected.

Many disagreed as standard bushings are not designed to handle that high of a temperature. Damage to the seals may occur due to the higher temperature.

4 The Chair asked for someone to research the issue and provide an update for the next meeting. Loren Wagner volunteered to head up the research with the assistance of Devki Sharma.

10.10.6 New Business

10.10.6.1 Task Force on PD Measurement on Bushings & CTs - Thang Hochanh, Chair

Tang Hochanh suggested that a specific setup be established for measuring external RIV results. Laboratories could provide their results anonymously for comparison. Ray Bartnikas commented that weighting on circuitry differences likely explains the difference in results and the manufacturers should come to an agreement on circuitry.

10.10.7 Adjournment

The meeting adjourned at 10:45 PM.

5 Dry Type Transformers Subcommittee – Unapproved Meeting Minutes April 13, 2010 – San Diego, CA USA 10.11 Dry Type Transformers SC Chair Charles Johnson Secretary Lewis Powell Acting Chair Paulette Powell Acting Secretary Casey Ballard 10.11.1 Introductions and Approval of Minutes The Dry Type Transformer Committee meeting began at 1:33pm Wednesday, April 13 in the Macaw/Cockatoo room of the Catamaran Resort Hotel with introductions of members and guests. There were 17 members (out of 32, therefore a quorum was reached with 53%) and 13 guests present. The minutes for the Houston (Motion by Tim Holdway and second by Marcel Fortin) and Toronto (Motion by Tim Holdway and second by Phil Hopkinson) meetings were approved just before the adjournment when a quorum was reached. The Chair then asked if anyone knew of any patent related issues; none were identified. 10.11.2 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: 10.11.2.1 IEEE PC57.12.01 - Dry Type General Requirements Chair Tim Holdway 1. The working group met in the Rousseau E-W Room(s) of the Catamaran Resort Hotel 2. The meeting was called to order at 11:02 AM by Chairman Tim Holdway

3. The meeting was convened with twelve (12) members (out of 23 – therefore a quorum was reached with 52% attending) and 14 guests present with 2 requesting membership.

4. The minutes of the Toronto Houston October 25, 2010 meeting were approved. Motion: Mark Gromlovits Second: Ray Nicholas

5. Attendees were asked if they knew of any patents that may be related to the work of this working group. No patents or patent claims pertinent to C57.12.01 were identified by working group members.

6. Old business

Nameplate

Tim Holdway asked if the DOE had made a ruling on the requirement of the text on the transformer nameplate. No-one was aware of a ruling and the issue will be discussed again in our fall meeting. Tim will contact John Caskey for details.

Reference Temperature

The proposal from Rick Marek from Toronto regarding reference temperatures for no load and load losses was accepted and will be incorporated into the new standard.

Partial Discharge

Unapproved Dry Type SC Minutes Spring 2011 San Diego.doc Page 1 of 7 Dry Type Transformers Subcommittee – Unapproved Meeting Minutes April 13, 2010 – San Diego, CA USA Several manufacturers performed testing on Open Ventilated transformers to help determine the new PD requirements (method and levels). The data was submitted, but the person who volunteered to collect the data was unable to attend the WG meeting. Therefore, Tim Holdway will request the data and distribute the analysis to the WG. No motions or decisions were made at this meeting regarding PD.

Marcel Fortin requested that the standard be updated to reference the proper instrumentation methods to be used in for PD.

Altitude Correction

In Houston, Rick Marek stated that Section 4.2.5 is vague on what dielectric tests are affected for altitudes above 3300ft (1000m). Discussions were held in Toronto without any motions made.

This meetings discussion focused on the accuracy of the values in Table 1. It was noted that these are the same values as used in 12.00, but no one could recollect how the values were created. Tim Holdway will search for the background information and Aleksandr Levin will review available data on the change in creepage distance in relation to altitude.

Miscellaneous Proposed Changes

Section 2 – Normative references will be reviewed by the WG chair and updated per the latest IEEE policy

Section 4.1.4 – Supply voltage - a motion was made by Marcel Fortin to define voltage harmonics, but was withdrawn when the list of excluded transformers was discussed

Section 4.1.6 – Operation above rated voltage – The last sentence will be reviewed and compared to ANSI C84.1 by Shankar Nambi.

Section 4.1.7 – Location – The question was raised if 12.55 was an IEEE or ANSI document. It was confirmed that this is an ANSI document.

Section 4.2.1 – Unusual service conditions – General – Marcel Fortin proposed to add two sentences, but there was not a second and the motion died.

Section 4.2.6 – Other unusual service conditions – A reference to IEEE C57.142 will be added to Section 2

Section 5.2 – Frequency – A motion was made to add 50Hz to the 60Hz ratings by Marcel Fortin, but no second was made and the motion died.

Section 5.7.2 – Angular displacement between voltages for three-phase transformers – the text ‘Unless otherwise specified’ will be added before the first sentence.

Table 5 – Dielectric insulation levels for dry-type transformers used on systems with BIL ratings 200 kV and below – Marcel Fortin made a motion to add up through 52kV. The WG Chair will determine if a Task Force is needed to investigate this proposal. No further actions were taken.

Unapproved Dry Type SC Minutes Spring 2011 San Diego.doc Page 2 of 7 Dry Type Transformers Subcommittee – Unapproved Meeting Minutes April 13, 2010 – San Diego, CA USA Section 5.10.3.5 – Partial discharge tests - Marcel Fortin made a motion to remove the reference to IEEE C57.124 but there was no second and the motion died

Section 5.11.2.1 – Classification of insulation systems – General – Marcel Fortin made a motion to change the word ‘should’ to ‘shall’. Casey Ballard seconded the motion and it was passed. Additionally, all references to IEEE C57.12.56 will be removed from this section and the entire document since that standard is no longer active.

Table 12 – Allowable temperature rise of external parts over ambient - Marcel Fortin made a motion to replace the 65°C with 60°C, there was no second and the motion died.

All comments submitted to the WG chair not discussed in the meeting will be distributed to the WG for the Fall 11 meeting

Task Forces

At the last meeting, it was decided to establish a task force to review the proposed revisions to the Temperature rise test procedure in section 11 of C57.12.90. We need volunteers for this task force, however no attendees stepped forward.

Other sections of the standard require review, i.e. section 10 (Partial discharge test) and section 12 (Short-circuit tests). Marcel Fortin had agreed to provide input, but we may want to consider a task force to review each of these sections. Marcel Fortin agreed to lead a task force on Short Circuit tests and requested to have a meeting room in the fall of 2011. The WG chair will follow up with the SC chair to see if this request can be met.

8. The meeting was adjourned at 9:50 AM.

10.11.2.4 WG for Revision of IEEE C57.16: Dry Type Reactors Chair Richard Dudley 1. The W.G. for the Revision of IEEE C57.16 (Dry Type Reactor T.F.) met on April 11, 2011, at 8:00 a.m. in the Rousseau E-W Meeting Room of the Catamaran Resort Hotel in San Diego, California. There were 12 members and 6 guests present. There are 24 members in the WG, including 5 corresponding members; therefore, there was a quorum. The following are the highlights of the meeting:

2. Introductions were made and the attendance list circulated. The Chairman, in particular welcomed Ken Edwards, Chairman of the IEEE Switchgear Committee, who was attending as part of his efforts to facilitate co-ordination on the redrafting of Annex F.

3. IEEE patent policy was reviewed and no issues were raised.

4. The minutes of the W.G. meeting in Toronto, Ontario were approved. Note: The minutes of the WG meeting in San Diego, California will not be approved until the WG meeting in Boston.

5. The latest version of Draft # 9 of PC57.16 was circulated to WG members prior to the meeting. Draft # 9 was prepared to address comments received on the initial ballot of PC57.16/D8. Redrafting Annex F was a major focus of Draft # 9; especially regarding achieving co-ordination with the IEEE Switchgear Committee. Focus of the rest of the meeting was on reviewing the latest version of Annex F plus a few minor issues elsewhere. Highlights of the discussions are as follows:

(i) The second note in F.1, which describes effectively earthed and non- effectively earthed grounding methodologies (including typical practice in NA vs. Europe) was reviewed and discussed. This note had been substantially rewritten by Pierre Riffon with input from Ken Edwards and various WG members. The main focus of the rewrite was to avoid any possible misinterpretation that could be construed as restricting trade by essentially endorsing a specific grounding practice in a specific geographical area. The note was accepted by the WG as written with a few minor changes. “Screened “cable will be defined; (each phase has a ground shield). “Belted” cable will be defined; (common shield for three phases). The correct reference is IEEE C37.011. The issue of seeming to restrict trade must be avoided in standards. The WG and guests agreed that a good topic for a Monday standards luncheon could be a presentation on legal issues in standards writing; including the issue of “restrictive trade”. Peter Balma and/or the Chairman will follow up with Ed Smith and others on the Administrative SC. (ii) Referenced standards in F.4 will be included in F.7 Supporting Documentation. (iii) Referenced document [B25} will be corrected; “IEEE Std C2-2007, National Electrical Safety Code”. (iv) The copyright footer will be corrected; “Copyright 2011 IEEE”.

6. The Chairman will make the noted corrections. He also requested that WG members review Draft 9 carefully and send any editorials to him by April 17. The objective is to initiate a recirculation ballot the w/o April 17. The WG meeting adjourned at 9:15 a.m.

Unapproved Dry Type SC Minutes Spring 2011 San Diego.doc Page 5 of 7 Dry Type Transformers Subcommittee – Unapproved Meeting Minutes April 13, 2010 – San Diego, CA USA 10.11.2.5 WG Dry Type Loading Guide C57.96 Chair Rick Marek 1. The third meeting of the working group was held in the Rousseau E-W Meeting Room of the Catamaran Resort Hotel at 1:45 PM with 11 members and 7 guests in attendance. Introductions were made, and the attendance sheet was passed around. The new patent slides were discussed and there were no patent issues. With 16 members there was a quorum and the minutes of the last meeting were approved as submitted.

2. The Task Force assigned to review the document and make suggestions for sections to be preserved in the annex so that they would not be lost in the revision process was asked to comment. Mangesh reported that he had submitted his suggestions that the two basic programs be moved to the annex. The Chair also indicated that all of the examples would be moved to the annex as well.

3. The Chair then reviewed the first draft. As introduction he noted that the draft was the result of four of the seven who volunteered to help compile. They were each assigned similar sections from C57.96, C57.96 annex and IEC 60076-12 with the instructions to select the best parts from each. The result is rough but gives a starting point.

4. The Chair questioned the value of the loading tables in the document and recommended removing them completely. There are about five pages based on the output of the programs requiring a great deal of work, now that the temperature classes have changed. A show of hands indicated three in favor and one against. However, in further discussion only two at the meeting were users and they had never used the document. In fact most in the room had not used the document. The conclusion was that we didn’t have the correct group mix to decide. One member suggested polling users, but there didn’t seem to be a reasonable mechanism to accomplish this. The Chair proposed removing the tables to see if anyone noticed or complained, since the programs used to make the tables would still remain in the annex. The issue was not resolved.

5. The Chair asked the members to review the draft before the next meeting and make suggestions on material that should be either removed or added.

6. Aleksandr Levin requested membership.

7. The meeting adjourned at 2:38 PM.

10.11.3 Status of Dry Standards The acting chair covered the status of the Dry Type standards and noted the documents had revision due dates or PARs expiring in 2011.  C57.12.59 – Through Fault Current Duration  C57.134 – Dry Type Hot Spot  The only document that did not have a WG chair was C57.94 - IEEE Recommended Practice for Installation, Application, Operation, and Maintenance of Dry-Type General Purpose Distribution and Power Transformers. When asked who would lead the reaffirmation, Dave Stankes volunteered.
