1. A 25,000 kVA, 13,800 V, 60 cycle, 3-phase Y-connected alternator supplies its rated voltage to the bus bars at 0.90 pf lagging. The voltage is then stepped-up with a AY transformer bank to 66,000 V for transmission and at the receiving end of the line is stepped-down to 13,800 V for distribution with a AA transformer bank. a. Determine the coil current of the alternator. b. AY transformer bank primaries and secondaries voltage. c. AA transformer bank primaries and secondaries current.
