power factor (plural power factors)
(electrical, engineering) The ratio of the actual power to the apparent power in an alternating current power system; specifically, the cosine of the phase angle between the voltage and the current.
The power factor is of interest because it is a measure of the power which does useful work.
A direct reading power factor meter can be made with a moving coil meter of the electrodynamic type, carrying two perpendicular coils on the moving part of the instrument. Source: Internet
Active power factor correction can be single-stage or multi-stage. Source: Internet
A high power factor is desirable since it minimizes the amount of reactive power needed by the load, reducing heat losses and maximizing efficiency. Source: Internet
A leading power factor signifies that the load is capacitive, as the load “supplies” reactive power, and therefore the reactive component Q is negative as reactive power is being supplied to the circuit. Source: Internet
As reactive current increases, the reactive power increases and the power factor decreases. Source: Internet
At low values of power factor, more apparent power needs to be transferred to get the same real power. Source: Internet
