Steps to Find the Source of Harmonics

Published by David Horning, November 2014. Power Monitors, Inc., White Paper: Steps to Find the Source of Harmonics Abstract. Harmonics are “Non-Linear” current or voltage in an electrical system. Any waveform that deviates from a perfect sine wave has harmonics. Any nonlinear load draws harmonic currents and therefore produces harmonic voltage distortion, by producing non-sinusoidalContinue reading “Steps to Find the Source of Harmonics”
