Question:
The motor of Problem 5.5 is supplied from a 460-V, three-phase source through a feeder whose impedance is Zf = 0.084 + j0.82Ω. Assuming the system (as measured at the source) to be operating at an input power of 40 kW, calculate the magnitude and phase angle of the line-to-neutral generated voltage Eaf and the field current If for power factors of
(a) 0.85 lagging,
(b) Unity, and
(c) 0.85 leading.
