Calculation detail

Formula: P = √3 × VL × IL × PF

Three-phase real power is calculated from line-to-line voltage, line current and power factor.

FORMULA VERIFICATION

Units, scope and reference

Reference: IEC three-phase power relationship P = √3VLI LPF.

Internal unit basis: V, A, dimensionless PF. Outputs: kW.

Valid conditions: Positive voltage/current; 0 < PF ≤ 1; balanced three-phase system.

Limitations: No efficiency, harmonics, demand, cable or protection calculation.
