Why is Power Factor important? The phase relationship between the ac-power-line voltage and current is related by a term called power factor. For a purely resistive load on the power line, voltage and ...

We hear it all the time — America’s electrical infrastructure is aging. Coupled with that reality, one of the issues that continues to surface around this ongoing discussion is knowing the reliability ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...
