NEMA Premium Motors
The member companies of the NEMA Motor and Generator Section established a NEMA Premium® energy efficiency motors program to provide highly energy efficient products that meet the needs and applications of users and original equipment manufacturers (OEMs) based on a consensus definition of "premium efficiency" and use of the NEMA Premium® logo for premium products.
NEMA Premium Transformers
The NEMA Premium Efficiency Transformer Program will help utilities, commercial buildings, and industrial plants incorporate super high-efficiency electrical transformers into their operations. NEMA originally set the standard for the efficiency of various types of distribution transformers with the publication of NEMA TP 1-2002 Guide for Determining Energy Efficiency for Distribution Transformers, which was later adopted by the U.S. Department of Energy (DOE) as the national energy-efficiency rule for low-voltage dry-type distribution transformers.
