Automatic Power Factor Correction System (APFC)

APFC is used for centralized reactive power compensation at the Point of Common Coupling (PCC) of electrical distribution system composed of varying loads.
APFC has a capacitor bank sub-divided into one or more number of step(s), which can be switched on & off automatically by using the APFC Controller and allied switching device.

The controller continuously senses the instantaneous magnitude and direction of the reactive power demand through line Current Transformer (CT) and Potential Transformer (PT). It generates a signal for switching and turns the capacitor bank on & off to provide the necessary reactive power (kVAr). This achieves the pre-determined value of Power Factor (PF).

Every HT consumer of electricity aiming to `IMPROVE or have UNITY POWER FACTOR` should possess the APFC system.

Better PF can bring in Incentive Gains!!
