In 2010 Schneider Electric released energy efficient transformers based on the Department of Energy (DOE) 10 CFR Part 431 Energy Conservation program for Commercial Equipment. On April 18, 2013 the United States Department of Energy (DOE) issued its final ruling on transformer efficiency for liquid-filled and dry-type distribution transformers. The ruling impacts single phase (10 kVA to 833 kVA) and three phase (15 kVA to 2,500 kVA). Distribution transformers manufactured in, or imported into the U.S. and its territories on or after January 1, 2016 are required to comply with the new DOE standards. Schneider Electric medium voltage transformers provide the solution to help end users to comply with this DOE ruling. Our commitment is for you to meet DOE compliance, improve energy efficiency, and create a positive impact on the environment by updating to our energy efficient products.
