Delta and Wye Circuit Equations Notes
Delta and Wye Circuit Equations
Typical 3-Phase Wiring Diagrams and Equations for Resistive Heaters
Definitions
ForBoth Wye and Delta (Balanced Loads) VP = Phase Voltage VL = Line Voltage IP = Phase Current IL = Line Current R = R1 = R2 = R3 = Resistance of each branch W = Wattage |
Wyeand Delta Equivalent WDELTA = 3 WWYE Open3-Phase Circuit Formulas: Open Delta Watts = 2/3 WDELTA Open Wye Watts = 1/2 WWYE Open 4-wire Wye Watts = 2/3 WWYE |
