Why we need to have a trip "control" oil in frame 9 gas turbines? why we can't just control the hydrauilic oil directely by solenoid valve to block it in trip cases?
Moreover, What is the use of trip oil pressure switches 63HG-1/2/3 protection?
If we lose the trip oil, the dump / stop valve will be closed anyway and trip the unit without this "trip oil low pressure" protection.
Can anyone explain please?
Thanks.
