Active Power Filter Cabinet (APF) is an intelligent harmonic control device based on power electronics technology. It detects harmonic currents in the power grid in real time, dynamically generates reverse compensation current, accurately offsets harmonic pollution, and solves power quality problems such as voltage fluctuations and three-phase imbalance.
Active harmonic filter is connected in parallel with non-linear loads, and uses one set of CT to detect the load current. The AHF system can also improve power factor (PF) and correct load imbalances in the power system.
