Subject: Terminology Clarification 

Colleagues,

Richard Parker had forwarded me a question from Wes Patterson of ABB requesting clarification on

some of DOE’s terminology relating to efficiency levels. Please see the attached letter for clarifying

discussion of that and corresponding updates to the published analytical results on the Distribution

Transformers webpage.

Best regards,

Brian Coffey
