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, ...

Zero sequence current, known as residual current or triplen harmonic current, is a phenomenon that occurs in electrical systems due to the presence of unbalanced loads or nonlinear loads. The primary reason for the presence of zero current is unbalanced loads. In a three-phase power system, the loads are ideally balanced, meaning that the three phases draw equal currents. However, in practical sce...
