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, ...

Why adjust the power factor of a generator? 1. When the generator is running, the power factor is too high, that is, the reactive power is too low, which reduces the reactive power margin of the system and affects the steady-state stability of the generator. Although the economy is improved, in the long run, this is in exchange for an increased probability of accidents. Once an accident occurs, th...
