displacement power factor
DPF
The displacement power factor is the power factor due to the phase shift between voltage and current at the fundamental line frequency. For sinusoidal (non-distorted) currents, the displacement power factor is the same as the apparent power factor.

displacement power factor
The ratio of real to apparent power for an inductive or capacitive linear load. (Displacement Power Factor= kilowatts60 Hz / kilovoltamps60 Hz, or FP (displacement) = kW60Hz / kVA60 Hz). For an inductive load the current lags the voltage and the power factor is called “lagging.” For a capacitive load the current leads the voltage and the power factor is called leading. In all cases if the current and voltage are in phase, the displacement power factor is unity (1). Displacement power factor ranges from unity to zero. The value of displacement power factor is also given by the cosine of the angle by which the current lags or leads the voltage. (see: Leading; Lagging; Linear Load; Power Factor.)

displacement power factor
Displacement factor is equal to the power factor for linear loads with sinusoidal voltages and currents.
pf = cos (angle1 - angle2)

apparent power factor
APF
The apparent power factor (APF) is the ratio of real power to apparent power, including harmonics.
This includes all harmonics. Harmonic currents decrease the power factor, even when there is no phase angle between voltage and current.
