A 150-hp, three-phase, 460-V induction motor has the design life of 20 years at 110C rise in

Question:

A 150-hp, three-phase, 460-V induction motor has the design life of 20 years at 110°C rise in conductor temperature above the ambient air. If it is continuously operated under unbalanced line voltages of 460, 440, and 420 V, determine:

(1) The percent voltage unbalance,

(2) The additional temperature rise when operating at rated load,

(3) The expected life at rated load, and

(4) The required horsepower derating for the motor to last the design life of 20 years.
