Abstract :
The results of a utility survey on surge protection practices for large generators are presented. The surge environment, 60 Hz withstand test value, designated impulse withstand, arrester protective levels, and insulation breakdown tests on two machines were compared. Factors included in the surge environmental were lightning, faults, HV switching, ferroresonance. opening surges, breaker failure, and system-side resonance. Several topics are identified for further study
