3-Phase Power Calculator — Free Online Calculator

Calculate three-phase power, line voltage, phase voltage, and current for wye and delta configurations.

How to Use This Calculator

Select wye or delta configuration, enter line voltage and line current, and power factor.

The Formula Explained

Three-phase total power: P = √3 × V_L × I_L × PF. In wye: V_phase = V_line/√3, I_phase = I_line. In delta: V_phase = V_line, I_phase = I_line/√3.
