thanks guys for the quick response. mc5w, the turbine governor that we employee is the HPC 640 GUIDE VANE CONTROLLER. It is digital and is implemented in an ABB Advant Controller 110 (AC110).
Mike,you guessed right the guide vane position is read by a mechanical link connected to one of the servomotors at one end and a position transducer on the other end. these however were checked and necessary adjustments were done.
my worry is that we've operated this machine for two years after refurbishment and we've never attended to the electrohydraulic convertor (actuator, TR10: ALSTOM), though we've opened it for the other machines. Now i'm faced with a situation were i have to check the hydraulic balance, mechanical tendency and the associated electrical compensation. i only have skeletal information and seriosly in search of detailed information.
