Product Description

Rongzhi 3 Phase Active Harmonic Filter Banks Product introduction

APF mainly uses FFT algorithm, DFT algorithm and three-phase circuit instantaneous reactive power theory algorithm. There are two kinds of APF, parallel type and series type, the former is used more; Shunt active power filter mainly deals with current harmonics and series active power filter mainly deals with voltage harmonics.

Rongzhi 3 Phase Active Harmonic Filter BanksTheoretical basis

Active filter compared with passive filter, good governance effect, mainly can filter out many times and high harmonics at the same time, will not cause resonance, but the price is relatively high! The practical application of safety factor is very low, the international common practice is to transformer boost, to ensure reliability, the relevant national departments also require the form of transformer boost and active filter combination, control high voltage harmonics!
