ABSTRACT:
In a steam turbine-generator system wherein the turbine shaft is subject to an electrostatic charge buildup, an active grounding system continuously maintains the shaft at substantially ground potential. A feedback circuit is connected between two brushes contacting the rotating shaft and is operable to generate a current of a magnitude to prevent electrostatic discharge as a function of the voltage as sensed by one of the brushes. A current sensor monitors the current supplied by the feedback circuit to the shaft and the output of the current sensor is utilized to diagnose various operating conditions of the steam turbine-generator system.
