3 Phase Power Calculator

Total power in a balanced three-phase load is sqrt(3) times line voltage times line current times power factor in both wye and delta, so the connection never appears in that formula and still decides everything inside the machine. Give this the line voltage and the resistance and reactance of one winding and it returns the phase voltage, the phase and line currents and the real, apparent and reactive power, with the same three impedances priced in the other connection beside it. The second action goes the other way and converts between line and phase values you already have. A delta load draws exactly three times what the same windings draw in wye, which is what a star-delta starter is buying.
