    OverviewLinear circuitsNon-linear loadsImportance in distribution systemsMeasurement techniquesMnemonicsPower-factor correction increases the power factor of a load, improving efficiency for the distribution system to which it is attached. Linear loads with low power factor can be corrected with a passive network of capacitors or inductors. Non-linear loads, such as rectifiers, distort the current drawn from the system. In such cases, active or passive power factor correction may be used to counteract the distortion and raise the power factor. The devices for correction of the power factor may be

  • Power factor - Wikipedia

    In electrical engineering, the power factor of an AC electrical power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1. A power factor of less than one indicates the voltage and current are not in phase, reducing the average product of the two.
