Power Factor Calculator
Easily calculate power factor (PF), apparent power, and reactive power for single-phase and three-phase circuits. Enter the real power, voltage, and current to get the results instantly.
Power Factor Formulas
- Single Phase: PF = 1000 × kW / (V × I)
- Three Phase (Line-to-Line): PF = 1000 × kW / (√3 × V × I)
- Three Phase (Line-to-Neutral): PF = 1000 × kW / (3 × V × I)
Example Calculations
- Single Phase: 10 kW, 230 V, 50 A → PF = 1000 × 10 / (230 × 50) = 0.870
- Three Phase (L-L): 20 kW, 400 V, 40 A → PF = 1000 × 20 / (1.732 × 400 × 40) = 0.722
Power Factor Table
| Type | kW | V | A | PF |
|---|
| Single | 10 | 230 | 50 | 0.870 |
| Three L-L | 20 | 400 | 40 | 0.722 |
