Effect of Electrical-Utility-System Voltage Harmonics on Induction Motors

摘要

Distortion of the electrical utility system voltage waveform can result in damage to or malfunction of user electrical equipment. An experiment was carried out to determine the effect of utility voltage harmonics on the temperature rise of single-phase induction motors. The results suggest that utility voltage harmonics do not significantly affect the operating temperature of a single-phase induction motor until the amplitudes of the harmonics are much larger than the amplitudes currently present in the US utility system.
