12 KVA, 440V. The 60HZ, 4-pole Y-connected synchronous generator's pole winding resistor is 42, and its incremental winding impedance is 0.02 + j1.242 phase. When the alternator is working in full capacity, its power factor is 0.8 forward and the excited current is 3A. Since the diner tails are 800w, in these conditions: a) Find the induced voltage (Et). b) Calculate the voltage regulation. c) Calculate the efficiency of the alternator
