The IEEE Standards Association (IEEE-SA) has approved the start of a new standard project IEEE P519.1, “Guide for Applying Harmonic Limits on Power Systems.” The standard will help utilities and building owners develop and execute harmonic limits within electric power systems.

The standard will provide application examples and procedures for controlling harmonics on power systems, as well as recommend limits for customer harmonic injection and overall power system harmonic levels.

The IEEE-SA also approved the revised standard for power distribution reliability indices, the start of revision projects to four power standards, and reaffirmed the continuation of five exiting standards.
