Mitigation of Harmonics on Low-Voltage Power Systems

From Aerovox Corp.
 

 

The term "harmonics" is used today to describe many power system problems. The following details some key concepts in understanding harmonic phenomena.

Any periodic wave can be described as a sum of sine waves with varying magnitude and frequency. This is known as a Fourier Series. Each term in the series is referred to as a harmonic of the fundamental frequency. In power systems, the fundamental frequency is 60 Hz. and the harmonics are integer multiples of 60 Hz. (180, 300, 420, etc.)
