APFC panel is for automatic power factor correction. in some cases of industrial applications the loading pattern of the entire network of the industry will change time to time. so if you connect a fixed compensation. it will not be in position to compensate exactly what is required. but in case of APFC panels you will have a microprocessor based relay which helps you to sense the load current instantaneously and the particular MC relay will hunt for capacitors to compensate and power factor improvement will be automatic.APFC is nothing but steps of capacitors connected to the contactor in turn connected to the breakers and relay.It doesnt require much of the manual support as of fixed compensation is concerned. Your power factor will be improved automatically, APFC will have a step by step compensation.
