Engineering calculator
Power factor
Apparent power, power factor and current from active and reactive power.
Inputs
Results
- Apparent power
- 500kVA
- Power factor
- 0.8
- Line current
- 695.6A
S = √(P² + Q²), PF = P / S
Assumptions
- Sinusoidal, balanced three-phase
Limitations
- Displacement power factor only — harmonics reduce true PF
