Question

A three phase star connected alternator feeds a delta connected induction motor

at a lagging power factor of 0.85. The voltage of each alternator phase is 1270 V.

The current in each phase of the alternator is 495 A. Find the current and voltage

of each phase of the motor. If the efficiency of the motor is 93%, determine the

mechanical output in horsepower developed by the motor. [4]​
