Unity Power Factor
Unity power factor (1 pf) loads have the current and voltage waveforms in phase with each other. In the example
below, a 2300 VA load with 1 pf has a real power value of 2300 W (2.3 kW).
Leading Power Factor
Loads with a leading power factor have a current waveform that leads the voltage by a factor equal to the load’s
reactance, usually between 0.8 and 0.95.
Using the same 2300 VA as in previous examples, a leading power factor of 0.766 has a real power value of 1762
W (1.76 kW).
