The 2005 Energy Act set Low Voltage Distribution Transformers efficiency levels for all products manufactured after January 1, 2007, and also authorized the Department of Energy (DOE) to analyze and mandate levels for all Distribution Transformers. Following its analysis, the DOE has chosen to increase the levels of efficiency on Low Voltage Transformers for all units manufactured after January 1, 2016. (10 CFR 431.192 April 2013).
This change requires manufacturers to redesign their products to comply with the new levels. The changes in 2007 were mostly core material, whereas this next level of efficiency has affected core configuration, core material, and coil sizes. The efficiency requirements also went from three significant digits to four significant digits allowing less manufacturing variability between units.
