Assume for the motor of Problem 2.3 that 50 kW and 440 V are taken as base values. Find the voltage in per unit at the motor side.
Problem 2.3
A 60-hp, three-phase, 440-V induction motor operates at 0.8 PF lagging.
a) Find the active, reactive, and apparent power consumed per phase.
b) Suppose the motor is supplied from a 440-V source through a feeder whose impedance is 0.5 + j0.3 ohm per phase.
