Steps to Find the Source of Harmonics

Read how to find the source of harmonics by following these five simple techniques.

Several methods are provided here to help identify the source of harmonic distortion. The best method depends on the details of the problem, especially if power factor correction capacitors are involved. With a systematic approach, and recording of voltage and current total harmonic distortion and individual harmonics, nonlinear loads can be identified. This is the first step towards mitigation or harmonic filtering.
