A three-phase motor is delta connected to a 415 V, 60 Hz line. If the line current is 25 A and the motor power factor is 0.75, how much power is consumed by the motor (a) Determine the size of the bank of three capacitors to improve the power factor of the motor to 0.95. The capacitors are delta connected. (b) If two of the motors work together, what is the size of capacitors to correct the power factor to 0.95 if delta connected?
