The terms used in the equations are identified below: VL= Line Voltage VP= Phase Voltage IL= Line Current (Amps) IP= Phase Current (Amps) WT= Total Watts R 1=R 2 = R 3 = Element Resistance I am programming an app for ordering 3 phase heaters, and I have an argument to resolve with a coworker. If the voltage and current to the motor are 400 V and 8. Three-phase motor Three-phase motors can be connected in star (Y) or delta (D) according to IEC 60034-8. This means that the voltage between lines A, B and C should be balanced, and each phase carries one-third of the total load current. 0 16.
