HY series intelligent combined anti-harmonic low voltage power capacitor is a new integrated module for reactive power compensation. which is applied in 0.4kV low voltage distribution network to save energy, harmonic mitigation and improve power factor, instead of the traditional reactive power compensation equipment composed of controller, fuse, switch, filter reactor and power capacitor.
It is mainly designed for the situation where the power network has a high harmonic and the traditional capacitors cannot be operated. It can not only meet the reactive power compensation, improve the power factor, but also restrain the influence of the corresponding harmonic on the capacitor and improve the power quality.
In the electrical environment where the main harmonic is 5 times or more, 7% of reactors shall be equipped, and the main harmonic is 3 times or more, 14% of reactors shall be equipped.
