Electrical Power Quality and Harmonic Concerns

Published by Chuck Gougler, International Association of Electrical Inspectors (IAEI) Magazine, Electrical Fundamentals – Electrical Power Quality and Harmonic Concerns, December 29, 2015 The Problem of Harmonics Harmonics are generated by nonlinear components in electrical systems, which distort the sine wave. Increasing usage of power electronics causes a corresponding increase in voltage distortion, or harmonics.Continue reading “Electrical Power Quality and Harmonic Concerns”
