Engineering (general)
generator protection system
A brush lift-off condition will prevent the field ground detector from operating. This is detected by calculating the RMS value of the ground current. It will normally have a nonzero value due to the capacitance of the field winding. A drop in this signal indicates an open circuit in the injection path and the field ground under current feature detects this condition.

Reference:
Brush lift-off
The invention is directed to a system and method for providing detection of a brush liftoff in a synchronous generator rotor circuit by monitoring and evaluating the capacitance between the field winding and electrical ground. A brush liftoff is declared when the monitored capacitance value undergoes a drastic reduction from its steady state capacitance value
