I would like to thank all of the reviewers who volunteered for this effort and donated their time, and would like to encourage everyone associated with IEEE Transformers Committee activities to consider becoming a Reviewer. I would like to encourage those Reviewers that already have an account on IEEE Manuscript Central to keep their profile information updated and complete the areas for key words and areas of interest. We need more reviewers and I encourage any of you that have not signed up as reviewers to sign up per the instructions at the end of this document.

It is important for all interested individuals to follow the norm for writing papers as provided in IEEE; the link is http://www.ieee.org/publications_standards/publications/authors/authors_journals.html and the link to upload the paper is http://mchelp.manuscriptcentral.com/gethelpnow/training/author/.

Please inform me at sanjib.som@siemens.com as soon as you do sign up so that we are able to utilize your efforts.

I would also like to take this opportunity to personally acknowledge the reviewers involved in the transformer committee who have been regularly and consistently reviewing papers. This is an important contribution since it maintains the high standards for our papers and it gives back to the industry their expert knowledge.

Special mention must also go out to the editors who have worked hard to make this possible; they are Dr Kulkarni, Dr. Francisco De Leon, Dr. Reza Iravani and Dr. Wilsun Xu.

Respectfully Submitted,

Sanjib Som

Editor, IEEE Transactions on Power Delivery from Transformer Committee

14.0Unfinished (Old) Business


No old business was discussed.

15.0New Business


Member ballot on WG P&P – Bill Bartley

Bill reviewed the purpose of the WG P&P. The WG P&P meets the requirements of the IEEE-SA Audcom document. Bill mentioned that the WG P&P and the Committee P&P templates do not match regarding meeting attendance requirements, but that we are required to meet each of the templates require

The WG P&P was distributed prior to the meeting for members review. A motion to approve the WG P&P as provided was made by Bill Bartley and seconded by Wally Binder.

There was no discussion. The motion was voted on and approved unanimously.


16.0Monday General Session Adjournment


A motion to adjourn the meeting was requested. Jerry Murphy motioned for adjournment and Hemchandra Shertukde seconded the motion. The motion was unanimously approved.

Thursday General Session

17.0Chair’s Remarks and Announcements – Don Platts


Don opened with comments on the meeting in general. He indicated that there were some complaints about the brief meetings in some instances and urged WG Chairs to make sure that they are making effective use of the meeting slots that they have been provided. In general, comments on the venue and Savannah were very positive which is a sign of a successful meeting.

Don thanked the host, Efacec, for the job they did at the meeting. Mike Bauer from Efacec addressed the group and on behalf of Efacec thanked everyone for coming. Jane Ann Verner also addressed the group and welcomed everyone to come to the Washington DC Metro Area meeting in October. She provided some transportation details and a brief list of things to see and do.


18.0Meeting’s Planning SC Minutes & Report – Gregory Anderson


Greg gave a brief overview of the meeting logistics. He expressed deep concern about the high number of no-shows at the Monday luncheon. He indicated it is not likely that this will be offered at no charge again as a result.

He talked about the future meeting in Washington DC and indicated that there has been no meeting set up as yet for Spring of 2015. He talked about the possibility of a hostless meeting when necessary to allow us to go to a particular location or part of the country.

Fall of 2015 is pretty firm for Memphis, TN. He also showed a list of several locations as potential future meeting locations.

Greg gave a brief overview of the Committee Finances including existing funds and meeting expenses.

Greg thanked a group of people who helped with making the meeting run smoother. He invited people to contact Tom Prevost if they have ideas for Tutorials for upcoming meetings.

19.0Reports from Technical Subcommittees (decisions made during the week)


Reports from each Technical SC were provided. Their minutes are included in full in the attached Annexes.

Dan Mulkey reporting for the UG Transformers and Network Protectors SC expressed a frustration on entry of rosters in the AM System. He requested that the default be changed from member to guest. Greg Anderson took that as an action item.



Don Platts indicated that the Administrative SC has been looking at the schedule and is working to manage the workload of the standards that are on the horizon.
