Clearing up Distortion

摘要

In this third part of my series on the most common power quality phenomena, I group several IEEE 1159 categories together under the general description of "distortion." Though one might argue that all power quality phenomena result in distortions of the voltage sine wave, these are the more steady-state variety, including harmonics, interharmonics, notching, unbalance (or imbalance), voltage fluctuations (or light flicker) and noise.
