A three-phase, 460-V, 60-Hz, 200-hp induction motor has design efficiency of 90% and pf of 0.85 lagging.

Question:

A three-phase, 460-V, 60-Hz, 200-hp induction motor has design efficiency of 90% and pf of 0.85 lagging. The cable reactance from the control center to the motor is 0.015 Ω/ph. If the motor pf were corrected to unity by placing capacitors next to the motor, determine the % voltage boost at the motor terminals.
