Typical 3-Phase Wiring Diagrams and Equations for Resistive Heaters
Definitions
| For Both Wye and Delta (Balanced Loads) | Wye and Delta Equivalent |
|---|---|
| VP= Phase Voltage VL= Line Voltage IP= Phase Current IL= Line Current R = R1 = R2 = R3 = Resistance of each branch W = Wattage
|
WDELTA= 3 WWYE WODELTA= ¾ WDELTA WOWYE= ½ WWYE |
