When designing the distribution system, the diameter of the N-phase cable was smaller than that of the A/B/C three-phase cable. At present, the distribution circuit on the first floor of the building … Continue reading CoEpower AHF Active Harmonic Filter helps solve problems caused by harmonics in the supermarket building’s Power System
