1. In synchronous generators, the frequency of the generated voltage is a. regulated by adjusting the mechanical power delivered to the prime mover. b. maintained constant by adjusting the excitation current. c. proportional to the rotation speed. d. Both a and c. 2. Overspeeding of a synchronous generator, upon a loss of load, a. depends on the reactive component of the load. b. is proportional to the active power delivered to the prime mover. c. depends on the generator excitation current. d. Both a and c. 3. Generator overspeeding can be reduced by a. decreasing the generator excitation current when the frequency of the generated voltage exceeds a certain value. b. removing power to the prime mover when the generated voltage is twice the nominal voltage. c. removing power to the prime mover when the frequency of the generated voltage exceeds a certain value. d. None of the above. 1.
