Steps to Find the Source of HarmonicsSteps to Find the Source of Harmonics

Find the source of harmonics by following these five simple techniques.


Harmonics are “Non-Linear” current or voltage in an electrical system. Any waveform that deviates from a perfect sine wave has harmonics.


Any non-linear load draws harmonic currents and therefore produces harmonic voltage distortion, by producing non-sinusoidal voltage drops across system wiring and transformers.


Harmonics are voltages or currents that are multiples of the fundamental frequency in a circuit. These are specified by their harmonic number or multiple of the fundamental frequency...
