Subject: Re: MV Liquid‐immersed LCC and NIA Results

Greg,

Thank you very much, for your questions.

> 1. Overall ‐ So that we can more effectively analyze this new

> 9/09/2011 results?

We plan to have a memo of changes ready for committee member prepared for tomorrow evening (Nov

4, 11)
> 2. Designs Used ‐ Can we assume that the designs defined in the 8/23

Yes, the engineering data used is the same data that was previously distributed to the committee. ZDMH

core designs were excluded only from the basecase, but persist in the standards cases. We plan to

release results, as a sensitivity, with ZDMH excluded entirely from the analysis later tonight or tomorrow

morning.

> 3. Chart 16 ‐ The label above the top table reads "Summary Results by  

> TSL for > Liquid‐immersed Transformers".  We believe this label should  

> read "Summary Results by EL for Liquid‐immersed Transformers".  Are we correct?

You are correct.

> 4. Chart 18 ‐ This chart describes 6 draft TSLs.  However, the chart  

> then shows 7 TSLs.  While TSL6 and TSL7 appear to be the same, is  

> there significance to this additional TSL?

There is no significance to the addition TSL its inclusion was an oversight ‐ it will be removed.

Thank you,

‐ Chris
