NEMA Publishes Standard for Harmonic Emissions LimitsJanuary 14, 2015
The National Electrical Manufacturers Association has 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.
