Subject: RE: Today's Conference Call on Medium-Voltage Transformers 

Richard and All:

 

With regard to the liquid immersed transformers, it is my hope that we can keep the 

committee alive and try to reach some realistic compromise that we can all live with. 

We should work hard at keeping all of the core iron producers in the game; they are 

critical to maintaining stability in this important market.

 

On January one of 2010, just two years ago, we started a major program to increase the 

liquid-immersed distribution transformer efficiency substantially. I think this go around, 

should just be a tweaking of those original efficiency values. I think EL-1 should be the 

point we should start with and compromise somewhere between that and EL-1.5. We 

should have a level for 95 KV BIL & below, another level for 125 KV BIL and leave 

the 150 & 200 KV BIL as they exist now.

 

These are my suggestions.

 

Jerry

Subject: Today's Conference Call on Medium-Voltage Transformers

Dear Colleagues, 

As you know, today's conference call is the last scheduled event of our negotiated rulemaking 

process on medium-voltage transformers. It is scheduled to run from 11 am to 1 pm, though we 

will end sooner if we finish our business sooner. 

I propose that we use the time to do two things: 

1) See if we can get to yes on an EL to recommend for DL 12, thereby creating a clear 

foundation an agreement on MVDT. 

I propose to focus on DL 12 because DLs 9, 10, and 11 are very small in sales (about 5 % of the 

market combined). E.g., 135 DL 11 units shipped in in 2009, whereas 1936 DL 12 units were 

sold. 

Also, these other DLs should scale off of DL 12, except for the low kVA portion (< 300 KvA) of 

DL 11 which is even smaller. DL 13 is a high-BIL version of DL 12 (and the upper end of 

DL11) and also can be treated as variant of DL12. Adjustment factors for DLs 9, 10, 11 and 13 

have been proposed by NEMA, but I would suggest that these can be treated separately as part of 

a technical exercise, that we can discuss if we can get to yes on the big issue, which is DL 12 

2) Discuss next steps, if any, for this group on liquid-filled transformers. 

Attached for your review is a chart containing the key LCC information for DL 12, with 2010 

price results and 2011 price results displayed side-by-side for ease of reference. Also attached 

are the full LBL and Engineering Analysis results for both 2010 prices and 2011 prices. 2011 

prices are what were are focusing on, but 2010 prices offers a useful reference (sensitivity if you 

will). 

I look forward to talking with you at 11. This will be a time for bottom lines. We know the 

arguments. 
Best, 

Richard Parker
