Power Factor Control refers to the management and maintenance of an acceptable power factor in electrical systems. Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical circuit. A low power factor indicates that the circuit is inefficient and requires more current to deliver a given amount of power. This results in increased energy losses, higher electricity bills, ...
