Great engineering online tool - 3 Phase Calculator

02/05/2026

3 phase calculator is an easy-to-use online tool to quickly determine the parameters of balanced three-phase circuits in both Delta and Star configurations. A balanced 3-phase circuit has the same voltages, currents, and power factors in all three phases.
This tool uses the following equations to determine voltages and currents for Star connection:

Vline = √3 × Vph
Iline = Iph

This tool uses the following equations to determine voltages and currents for Delta connection:

Vline = √3 × Vph
Iline = Iph
