Energy Conservation Program: Test Procedure for Distribution Transformers (27 page(s), in English)

The U.S. Department of Energy ("DOE") proposes clarifying amendments to the test procedure for distribution transformers to revise and add definitions of certain terms, to incorporate revisions based on the latest versions of relevant Institute of Electrical and Electronics Engineers (IEEE) industry standards, and to specify the basis for voluntary representations at additional per-unit loads (PULs) and additional reference temperatures. The proposals in this NOPR are minor revisions that do not significantly change the test procedure. Therefore, none of the revisions would pose undue burden on manufacturers. DOE is seeking comment from interested parties on the proposal.
