Question

AC generator power ratings are based on: Select one: a. the insulation rating of the windings of the generator. b. generator speed when developing the maximum current output. c. the total voltage and current capacity for each pole of the generator. d. the ability of the prime mover to overcome generator losses and dissipate heat. e. the size of the prime mover and the maximum speed of the generator. Placing two generators in parallel with a mismatch in frequency will result in: Select one: a. large opposing voltages and a decrease in output current. b. lowering of system frequency by the difference of the two generators. c. the generator with the lower frequency being picked up as a reactive load. d. high current surges until frequency matches. e. the generator with the lower frequency being picked up as a real load. Placing two generators in parallel with a mismatch in frequency will result in: Select one: a. lowering of system frequency by difference of the t

Explanation / Answer

Option (d) is correct

It is based on the ability of prime mover to overcome the heat dissipation and generator losses

Next two questions are same

Option (c) is correct

The generator with lower frequency is being considered as a reactive load.
