The induction motor of Problem 9.9 is supplied from an unbalanced two phase source by a four-wire
Question:
The induction motor of Problem 9.9 is supplied from an unbalanced two phase source by a four-wire feeder having an impedance Z = 0.32 + j1.5Ω/phase. The source voltages can be expressed as Vα = 235 < 0°, Vα = 212<78°. For a slip of 5 percent, show that the induction-motor terminal voltages correspond more nearly to a balanced two-phase set than do those of the source.
