POWER FACTOR (TRUE OR TOTAL POWER FACTOR)

This is the ratio of real power to apparent power being supplied to any electrical load, linear or non-linear. Another way to describe power factor is: the ratio of the power that actually does useful work to the power that must be supplied to get the work done. If all the power supplied does useful work, the ratio is one (1) and the power factor is unity. (Power Factor (true) equals the real power, which is delivered at 60 Hz, divided by rms apparent power, or FPTrue = kW60 Hz / kVArms) Power factor ranges from zero (no useful work done) to unity. Resistive loads such as heaters have a unity power factor. When non-linear loads are being powered and harmonic currents are flowing in the system, true power factor is always lower than displacement power factor. (see: Linear Load; Nonlinear Load; Displacement Power Factor; rms)
