The governor control switch of an alternator is moved to the 'raise' position. What will be the effect of this action?

Correct Answer: Option C — raise the no-load speed setting of the governor

Moving the governor control switch to the 'raise' position increases the spring tension or reference set-point of the prime mover's governor, thereby raising the no-load speed setting and increasing the operating frequency of the alternator in accordance with standard marine generator control principles.
