The IEEE standard 3002.8-2018, “Recommended Practice for Conducting Harmonic Analysis Studies of Industrial and Commercial Power Systems,” addresses the requirements for performing power-system harmonic analysis studies in industrial and commercial power systems due to increasing load nonlinearities and control devices.

What follows are ways to measure and reduce or eliminate the problems caused by harmonics.

Successfully Measuring Power-System Harmonics

Harmonic analysis is a discipline that’s quite different from any traditional methods used to solve problems in power systems. Finding solutions once a system is at the power system frequency will not do the job, though. The harmonic problem must be solved at multiple frequencies.
