A 1,000 kVA, 3,200V, single phase 60Hz, 24 pole alternator/generator has an stator winding re-sistance of 0.1 ohm from line-to-neutral. The rotor is not a permanent magnet but a separately pow-ered electromagnet (field windings) that takes 100 A at 120 V. The power to run the filed is consid-ered a loss. The friction losses, including windage, are 15 kW. The core losses are 20 kW. a) Determine the output (line ) current based on kVA and ouput voltage. b) Calculate the total I2R resistance loss. c) Calculate the efficiency. (93.3 % answer) (Generator input = output + losses.
