NEMA Publishes ANSI C82.77-10-2014 American National Standard for Lighting Equipment—Harmonic Emission Limits—Related Power Quality Requirements

​The National Electrical Manufacturers Association (NEMA) published ANSI C82.77-10-2014 American National Standard for Lighting Equipment—Harmonic Emission Limits—Related Power Quality Requirements.

This standard specifies harmonic limits, their methods of measurement, and power factor for lighting equipment. With the increased use of sensitive electronic equipment, harmonic distortion on power lines is an ever-increasing issue for residential, commercial, and industrial users. Developing a standard that specifies the limits of total harmonic distortion helps ensure that a manufacturer's equipment meets industry guidelines and protects the overall quality of the power system.

ANSI C82.77-10-2014 may be purchased for $69 in electronic or hardcopy format on the NEMA website.

NEMA is the association of electrical equipment and medical imaging manufacturers, founded in 1926 and headquartered in Rosslyn, Virginia. Its 400-plus member companies manufacture a diverse set of products including power transmission and distribution equipment, lighting systems, factory automation and control systems, and medical diagnostic imaging systems. Total U.S. shipments for electroindustry products exceed $100 billion annually.
