1 Working principle
The Acrel® Active Power Filter ( APF ) is connected in parallel with the loads.A current generator (power unit) that converts the control signals generated by the filter controller into the filter compensation current. A filter controller that determines the anti-harmonic current to be injected based on the line current measurements and the user's requirements. The line current measurements are obtained from current transformers (CTs) . The user enters his requirements by means of the user interface.
