A 3-phase, star-connected alternator has a resistance of 0-5 2/phase and a synchronous reactance of 5 02/phase. It is excited to give 6600 V (line) on open circuit. Determine the terminal voltage and voltage regulation on full-load current of 130 A when the load p.f. is (i) 0-8 lagging (it) 0-6 leading [(1) 3340 V (phase value); 14-1% (ii) 4260 V (phase value); -10-6%) Pay attention, expert, the final result is given, meaning that the result of your solution must be the same as the given result
