Calculateur de Three-Phase Power
Calculate three-phase electrical power from voltage, current, and power factor.
Formula and method
This calculator computes Real power directly in your browser without sending data to an external server.
Mathematical formula
- Real power:
√(3) × voltage × current × powerFactor
Variables and parameters
- Line voltage (voltage): default value 400 V.
- Current (current): default value 10 A.
- Power factor (powerFactor): default value 0.9.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
