To test an automatic low lube oil pressure trip on an idling turbo-generator and at the same time prevent the chance of bearing damage, you should __________.
A
secure the steam supply valve to the throttle valve and observe the oil pressure as the throttle trips during the slowdown and ensure a supply of oil with the hand or standby pump when the pressure drops to 2-3 psi
B
actuate the overspeed trip, making a note at what pressure the oil is dumped from under the operating piston
C
ensure the standby lube oil pump, if so equipped, is properly lined up and set in the "auto" mode, or the hand pump is being operated and then actuate the emergency trip
D
close the generator steam throttle valve and then ensure a supply of oil through the hand or standby pump when the pressure drops to 5-6 psi
