- What was the cause for the turning gear overhaul?, and what are the impacts to the turning gear?

- what is the set point speed (rpm) of your turning gear? what is the driver of your turning gear? (oil or moto


what i think, it is impossible to have rotor rotates 6 rpm faster than turning gear if they are still coupled, once the governor opens further, rotor speed increases and higher than turning gear and they will be uncoupled. So the rotor will accelerate to its 1st set point and so on, and turning gear will not in service.

so if rotor and turning gear uncoupled during acceleration, it is normal and it will not trigger trip of turbine.
