Revisions to Energy Test Procedure for Distribution Transformers under Consideration
The U.S. Department of Energy is seeking comments, data and information by 9 July on a proposal to clarify the energy test procedure for distribution transformers. Specifically, the DOE is proposing to revise and add definitions of certain terms, incorporate revisions based on the latest versions of relevant Institute of Electrical and Electronics Engineers industry standards, and specify the basis for voluntary representations at additional per-unit loads and additional reference temperatures. The agency notes that these changes constitute minor revisions that do not significantly change the test procedure and, as such, they would not pose an undue burden on manufacturers.
