Subject: Re: Use of ZDMH as a core material

Date: Thursday, October 27, 2011 7:56:20 PM

All,

I want to be clear that this proposal is to filter out ZDMH as a core

material only in the basecase. ZDMH would remain a potential core

material when analyzing the impacts of higher efficiency levels in the

standards cases.

The proposed filtering would be for all classes of transformers

covered by the analysis: MVLF, MVDT, and LVDT.

Thank you,

- Chris
