Formula

PF = P(W) / S(VA)

S = V·I (×√3 three-phase)

How to Use

  1. Enter real power P, voltage V, current I.
  2. Choose connection.
  3. Get power factor PF.

Case Studies

P=2200 W, V=220 V, I=10 A (DC)

S = 2200 VA, PF = 2200/2200 = 1.

FAQ

PF=1?

Resistive load PF=1; inductive/capacitive <1.

Improve PF?

Add capacitors in parallel to raise PF, cutting reactive power.
