DPF therefore does not include the effect of non-linear harmonic currents. PF Power Factor or Total Power Factor. Active Power divided by Apparent Power. PF is a measurement of the efficiency of an AC power transmission and distribution system, including the effects of harmonics. All measurements are true-rms.
All measurements are true-rms.
Watts measure that portion of electrical power which does work, which by definition includes heat losses. VA is computed by taking the product of the rms values of voltage and current. It is a measure of the total electrical power capacity of a distribution system or component equipment. In addition to Watts, it includes the contributions of VARs and harmonic currents. VARs are typically first present in a distribution system as a result of inductive loads such as motors, reactors and transformers.
