How To Calculate A Power Factor Complete Guide

For example calculate the full load current of a 50 kW 480 V 3-phase generator. P is Power kW Z gas compressibility factor can be defined on an Amagat diagram by calculating the reduced pressure and reduced temperature of the gas P 1 Pressure inlet compressor kPa P 2 Pressure outlet compressor kPa Q m Compressor throughput kgs kGas isentropic coefficient. The power factor formula is.

PF cos f 1000 P kW 3 V L-LV I A Apparent power calculation.

If on the contrary the real power is equal to zero then the apparent power is also 0. In AC circuits the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. 781116971 046 This can also be expressed as a percentage therefore you multiply 046 by 100 giving you a power factor of 46. As mentioned above to achieve power factor correction the magnitude of the reactive power created by the parallel capacitor must be equal to the reactive power created by the inductance.
