Question 399Motor Plants - Assistant Engineer
70% to passDiesel engines driving alternators operating in parallel must maintain a set frequency regardless of load changes. The governor characteristic used to accomplish this is known as_______________.
Aactuation
Bsensitivity
Ccompensation
Dpromptness
AI Explanation
The correct answer is C) compensation. The governor characteristic used to maintain a set frequency on diesel engines driving alternators operating in parallel is known as compensation. This is because the governor system needs to compensate for changes in load in order to maintain the desired frequency. The compensation mechanism allows the governor to adjust the engine's fuel supply to keep the frequency constant, despite fluctuations in the electrical load. The other options, such as actuation, sensitivity, and promptness, while important governor characteristics, do not specifically describe the mechanism used to maintain frequency under varying load conditions.
