Power Distribution Equipment
Description
Active power filter (APF) is designed to filter the harmonics injected by non-linear loads in power networks. It can analyze the line current harmonics drawn by the loads and generate a compensation current dynamically at the opposite phase angle, thereby & quot;neutralizing& quot; the harmonic currents.
