APFC Panel means Automatic Power Factor Correction Panel. In some cases, in industrial applications, the loading pattern of the entire network will change from time to time. So if that type of Industries connect a fixed compensation. It will not be in a position to compensate exactly what is required for Power Factor.

Automatic Power Factor Correction or APFC panels are electrical control panels used for this purpose. Being efficient, these panels maintain the power factor of an electrical system by automatically regulating the reactive power (kVAR) required by inductive loads.
