EnersineTM APF measures and monitors the entire load current through external auxiliary coupling current transformers (CT) mounted on the AC line, removes the fundamental frequency component and injects opposite phase harmonic current to cancel harmonic current in the electrical distribution system. By cancelling the harmonic currents in the circuit, there will be:
