(Solved):  The generator is 2-pole, -connected (not Y-connected), 60 Hz. The internal generated voltage ...

The internal generated voltage EA of a Y-connected, three-phase synchronous gen- erator is 14.4 kV, and the terminal voltage V, is 12.8 kV. The synchronous reactance of this machine is 4.1, and the armature resistance can be ignored. (a) If the torque angle of the generator 8 = 18°, how much power is being supplied by this generator at the current time? (b) What is the power factor of the generator at this time? (c) Sketch the phasor diagram under these circumstances. (d) Ignoring losses in this generator, what torque must be applied to its shaft by the prime mover at these conditions?
