Alternating Current
Three-Phase Power Calculator
Three-Phase Power converts the entered electrical measurements into three-phase real power. Use it to calculate balanced three-phase power.
Enter values for three-phase real power
Use one consistent electrical operating case for all fields.
How Three-Phase Power works
For this case, apply P = √3 × VL × IL × PF. Three-Phase Power uses Line voltage, Line current, Power factor to report Three-phase real power. For impedance magnitude, use Parallel RLC Impedance Calculator.
With the loaded values, three-phase real power evaluates to 19,509.82 W. Compare low and high values without overwriting the starting case.
Inputs for Three-Phase Power
Line voltage, Line current, and Power factor belong to Three-Phase Power. Keep source units with line voltage.
Defaults make the page immediately testable, but they do not describe a universal installation. Compare this result with Power Factor Correction Calculator when required capacitor reactive power is also needed.
- Line voltage
- Example entry: 400 V.
- Line current
- Example entry: 32 A.
- Power factor
- Example entry: 0.88.
Reading the Three-Phase Power result
This output represents Three-Phase Power.
Apply required margins only after identifying the correct equipment standard.
Measurement and units
Use RMS quantities unless a field explicitly asks for peak amplitude. Check prefixes on line voltage.
Record conversion choices so comparisons stay traceable.
Limits of this calculation
Unbalanced phase currents require phase-by-phase calculation.
Only variables shown in the equation affect the numerical output. Unentered effects remain outside Three-Phase Power.
