Question:

A three-phase, 460-V, 60-Hz, 500-hp induction motor has a design efficiency of 92% and pf of 0.80 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 rise at the motor terminals.
