When starting a turbo-generator, you must provide lube oil pressure to the governor power piston by means of _______________.
AI Explanation
The correct answer is A) the hand operated or auxiliary lube oil pump.
When starting a turbo-generator, you must provide lube oil pressure to the governor power piston by means of the hand operated or auxiliary lube oil pump. This is because the main lube oil pump is not running at the start-up, and the generator cannot be started without providing the necessary lube oil pressure to the governor power piston. The other options, such as a line from the gravity tank or the other generator, would not be able to provide the required lube oil pressure for the initial start-up of the turbo-generator.
