Question 316Steam Plants - 1st Asst/Chief
70% to passWhen starting a turbo-generator, you must provide lube oil pressure to the governor power piston by means of _______________.
Aa line from the other generator
Ba line from the gravity tank
Cthe hand operated or auxiliary lube oil pump
Dthe main lube oil pump
AI Explanation
The correct answer is C) the hand operated or auxiliary lube oil pump. When starting a turbo-generator, the hand operated or auxiliary lube oil pump must be used to provide lube oil pressure to the governor power piston. This is because the main lube oil pump is not running when the generator is not in operation, so it cannot provide the necessary pressure. The other options are incorrect - using a line from the other generator or the gravity tank would not provide the required lube oil pressure to the governor power piston during start-up.
