Subject: RE: MV Dry

‐ Type LCC and NIA Results

Dear Committee Members,

The draft LCC and NIA results for dry

‐ type medi um

‐ voltage transformers reflect

revisions to the engineering analysis ONLY for product Classes 11 and 12. We did

not have time to complete our review of the other representative units. These are

the Medium BIL 300KVA and 1500 KVA units which represent the vast majority of

product shipments.

In addition to th e Draft Trial Standard Levels presented for discussion in the

LCC and NIA results presentation, NCI suggests another approach to establishing

Trial Standard Levels which is based on scaling the results of the Medium BIL

analysis onto the Lower and Higher BIL product classes. For example:

Trial Standard Level 1 woul d represent a 10% reduction in Losses from the current

Standard for all KVA ratings and for all BIL classes Trial Standard Level 2 would

represent a 20% reduction in Losses from the current Standard for all KVA ratings

and for all BIL classes Trial Standard Level 3 would represent a 30 % reduction in

Losses from the current Standard for all KVA ratings and for all BIL classes

Trial Standard Level 4 would represent a 35% reduction in Losses from the current

Standard for all KVA ratings and for all BIL classes Trial Standard Level 4 would

represent a 62% reduction in L osses from the current Standard for all KVA ratings

and for all BIL classes

The % reductions in losses shown above are consistent with ( based on) the EL

values for DL 12. We welcome comments, and possible refinements, on this proposed

approach.Best Regards

Mike Rivest

P.S. In considering the TSL approach describe, I recommend that you the look

again at the Presentation on Draft Standard Levels Prepared by Wes Paterson.

Thanks you,

‐ Chris
