Overview of Active Power Filter APF-1000
APF-1000 Active power filter has various compensation modes (harmonic, reactive power, three-phase unbalance and capacitor switching control), which can simultaneously make the said various compensation, and the proportion of compensation capacity by harmonic, reactive power, and three-phase unbalance can also be set, comprehensively solving the problem of power quality of the low-voltage distribution side;
