1 Opening of the Meeting

1 Introductions

The Chair opened the meeting with group introduction

2 Attendance

Membership count was taken with the following results: 23 of 38 members were present and 82 guests for a total of 105 attendees. There were 11 new membership requests. There was a quorum.

3 Chairman’s Remarks

The Chair informed the SC that an award was presented to the DC working group who completed the first joint IEEE/IEC standard. The WG was led by Mr. John Graham for IEC and Mr. Les Recksiedler for IEEE.

The Chair introduced the new Working Group Chair for PC57.19.04 GSU Bushing Standardization, Mr. Scott Digby.

The Chair stressed the importance for all WG Chair’s to ensure their scheduled meetings take place if they are unable to attend. They need to verify that the Vice Chair and or Secretary are present to host the meeting. The conference attendees travel great distances to support the working groups and task forces and we must ensure that scheduled meetings do take place.

The Chair stressed that it is very important that we all need to be more diligent to avoid commercialization during the various meetings at the conference. He mentioned that it has been brought up several times in the past and improvements still need to be made.

The Chair reviewed the WG and TF schedule with the group, see Appendix A of this report.

4 Working Group and Taskforce reports

1 C57.19.00-2004 – Keith Ellis, Chair

No Meeting was held. Mr. Ellis reviewed the standard and did not find anything in need of updating but asked the group to review and send him anything they deemed necessary to be brought up for discussion as a possible revision.

2 WG PC57.19.01-2000 – Dr. Shibao Zhang, Chair; David Wallach, Secretary

See complete minutes in Appendix B of this report.

3 C57.19.100-2012 – Tommy Spitzer, Chair, not present.

The guide was published February 2013, as such no meeting was held. The Chair informed the SC that Mr. Spitzer had to leave the conference early. However, he did discuss with Mr. Spitzer the need to have a version of overloading added back into the standard and therefore he should start establishing a method to complete that for the next revision.

4 WG PC57.19.04 – Chair, Scott Digby; JD Brafa, Vice Chair; Secretary, Op

See complete minutes in Appendix C of this report.

5 IEC / IEEE 65700.19.03 – Les Recksiedler (IEEE) and John Graham (IEC), Co-Chairs

The first dual logo standard was approved June of 2014, as such no meeting was held.

2 External Liaison reports

1 IEC Bushing Standards Activity – John Graham, IEEE Liaison

Mr. Graham informed the group that IEC will be defining a new term. It will likely be RIS for the new resin impregnated synthetic bushings. Following Mr. Grahams briefing Mr. Sharma noted that IEC seems to have discontinuity in cantilever values listed in their bushing standard and the bushing cantilever values listed in the IEC circuit breaker standard. See complete minutes in Appendix D of this report

2 IEEE 693 – Eric Weatherbee, IEEE Liaison

Mr. Weatherbee gave a brief presentation on the current state of the IEEE 693 revision progress. The presentation was submitted for hosting on the website. Following the presentation the Chair informed the SC that only two transformer and bushing OEMs attend the 693 meetings and urged the SC attendees to consider attending the 693 meetings so that there is an appropriate useable update.

3 WG PC57.160 – Thang Hochanh, Chair; Thomas Sizemore, Secretary

See complete minutes in Appendix E of this report.

3 Unfinished Business

1 Oil to SF6 Bushings – John Graham

Mr. Graham asked if the group wants to have this defined in a standard. It was mentioned that Mr. Elliott stated in the previous SC meeting that the current form of 00 and 01 exclude these types of bushings and therefore are beyond the scope and would require significant revision to include these so it may be best to start a new standard. Mr. Devki Sharma mentioned that he is a member of the GIS SC and that they use the existing IEC document for terminations and the IEEE bushing standard for dimensional values and he feels that is sufficient. The Chair suggested that we should form a taskforce to determine what the best way to proceed is. Mr. David Geibel agreed that a new standard should be written to look at these types of bushings. The Chair presented three alternate methods to the members for vote on how they would like to proceed however no agreements could be made at this time. It was suggested by Mr. Wayne Johnson that a formal written version be emailed to the members containing each proposal so that they could be better assessed.

2 Study Report on Distribution Transformer Bushings – Stephen Shull

The Chair informed the SC that Mr. Stephen Shull will Chair the TF for establishing a bushing standard that covers this type.

4 New Business

1 Taskforce for Composite Bushings – John Graham

The Chair expressed a need to form a taskforce to look at the definition, and application of composite bushings based on the comments made during the recent SC meetings. The Chair asked for the SC members to vote on the formation of the Taskforce and did receive a quorum vote of 18 members in agreement. The Chair then asked Mr. John Graham if he would be interested in leading this Taskforce which he agreed to do so.
