DOE tightens efficiency standards for distribution transformers

摘要

On Oct. 12, 2007, the U.S. Dept. of Energy (DOE) issued in the Federal Register, 10 CFR Part 431, Energy Conservation Program for Commercial Equipment, Distribution Transformers Energy Conservation Standards; Final Rule. This regulation covers all distribution transformers manufactured after Jan. 1, 2010, and defines the minimum efficiency standards in the design of distribution transformers under federal law. However, not everyone agrees on whether these new standards will produce the intended effect; meanwhile, the window to order less-expensive transformers is closing.
