Measurement of input current harmonic wave and methods of reducing harmonic wave

Fang Xie

Abstract

In power system,power sources pollution caused by nonlinear load is taken people more and more attention. Regarding to the problem,we analyze a typical nonlinear load current harmonic wave through waveform method and DC measurement. The influence of distortion rate of harmonic wave on the power factor is discussed,and finally gives several methods to reduce the harmonic wave.
