Question 242Motor Plants - 1st Asst/Chief

The correct answer is A) increase the governor output power. Increasing the oil pressure acting on the power piston of the hydraulic governor will increase the governor output power. This is because the power piston is responsible for generating the force that opposes the centrifugal force acting on the flyweights, which ultimately controls the governor's output power. By increasing the oil pressure on the power piston, you increase the force it can exert, leading to a higher governor output power. The other options are incorrect because: B) decreasing the speed droop is not a direct result of increasing the oil pressure; C) the overspeed trip setting does not need to be adjusted simply by changing the oil pressure; and D) increasing the oil pressure would actually decrease the speed droop, not increase it.
