APFC (Automatic Power Factor Control)
Depending on the loads in operation, various levels of kVAR compensation are required to maintain proper
power factor. The APFC panel contains a multi-step relay which is connected to multiple capacitors and a
microprocessor controller which is programmed to control the switching operation of the relay. The voltage and current are measured on the feeder which is providing supply to the entire group of loads to determine the uncompensated power factor. Then, as per the ratings of the different capacitors used in the APFC and the
