IEEE Switchgear - HVCB Standards Status 2005-10-03

Chair Bill Bergman [email protected] Secretary Rich York [email protected] Number Title Status WG Chair Actions underway C37.04- IEEE Standard Rating requires Jeff Jeff Nelson will initiate a PAR for 1999 Structure for AC High- reaffirmation Nelson a corrigendum to eliminate the Voltage Circuit problem of ongoing distribution of Breakers Rated on a incorrect version of C37.04. An Symmetrical Current extension will be requested for Basis C37.04 to extend its validity. Jeff Nelson will conduct a reaffirmation ballot The ballot letter will include the corrigenda as a list of know deficiencies. Since the standard cannot be reaffirmed if the corrigenda changes are made. Later when the “a” and “b” series of C37.04 and C37.09 are complete and C37.06 has been balloted, HVCB will start the complete revision of C37.04 and C37.09. We will likely combine C37.04, C37.04a, C37.04b and C37.06 into one document and C37.09, C37.09a and C37.09b into another separate document. NEMA SG-4 will be incorporated into the relevant C37.04 and C37.09 sections. C37.04a- IEEE Standard Rating approved Roy valid 2003 Structure for AC High- Alexander Voltage Circuit Breakers Rated on a Symmetrical Current Basis---Amendment 1: Capacitance Current Switching C37.04b IEEE Standard Rating ready for ballot Kirk Smith K. Smith working on the (P2005?) Structure for AC High- PC37.04b document for TRV Voltage Circuit revisions. Breakers Rated on a Draft submitted to IEEE for pre- Symmetrical Current ballot editorial approval in Basis---Amendment 2 February 2005 and received Required TRV Values: comments from IEEE in March 2005. Comments appeared to be mainly editorial. However, the document must now use the newest version of the style guide. Kirk hopes to get that done within the next few weeks so the ballot can start. PAR has been extended to December 2006. C37.06- American National PAR issued Georges As discussed in Spring 2005 2000 Standard for 2003; ready for Montillet Florida, C37.06 requires a Switchgear--AC High- ballot of change of PAR due to title Voltage Circuit modified draft change, the comments of IEEE

The PAR expires at the end of the year so an extension is likely required. Potential issues/objections with:  Format to new Style Guide since this document intentionally uses IEC format.  References to IEC 62271-1 (60694) rather than PC37.100.1 common clauses (which is still in balloting stage)
