Energy Conservation Program: Test Procedure for Distribution Transformers

FR Abstract

The U.S. Department of Energy (``DOE'') is amending the test procedure for distribution transformers to revise and add definitions of certain terms, update provisions based on the latest versions of relevant industry testing standards, and to specify the basis for voluntary representations at additional per-unit loads and additional reference temperatures. The updates in this final rule will not significantly change the test procedure.

transformer test procedure. 71 FR 24972, 24973. As such, the DOE test procedure incorporated a number of the changes that this revision made to the rule language â¦ manufacturers to retest and recertify, because such an incorporation by reference would require updating a majority of the current test procedure. 84 FR â¦ discussed, the DOE test procedure is based on (but does not incorporate by reference directly) NEMA TP 2-1998, NEMA TP 2-2005, as well as four IEEE standards
