The anti harmonic intelligent capacitor is switched according to the full wave reactive power, which can eliminate other unnecessary waveforms (resonances). If the fundamental wave reactive power is used, other high and low harmonics can not be filtered out during the reactive power. The good thing depends on whether the high and low harmonics affect the normal use of electrical appliances.

Anti harmonic intelligent power capacitor is a new generation of reactive power compensation equipment, which is used in 0.4kV low-voltage distribution network to save energy, filter harmonics and improve power factor. It replaces the traditional reactive power compensation equipment composed of intelligent reactive power compensation controller, fuse, switching switch, filter reactor and power capacitor.

The anti harmonic intelligent power capacitor is designed for the situation that the harmonic content of the power network is high, and the conventional intelligent capacitor can not use the normal operation of electrical appliances after compensation. It can not only meet the reactive power compensation, improve the power factor, but also eliminate the influence of higher harmonics on the system, and improve the power quality.
