Abstract: The surge protection practices for large generators were reviewed through a utility survey. The surge environment of large generators, their 60 Hz withstand test value, their designated impulse withstand, arrester protective levels, a n d insulation breakdown tests on two machines were then compared. Several topics are identified for further study including arrester protective margins, zinc oxide arrester voltage endurance, stuck breaker poles on fault clearing, breaker out-of-phase closing surges, step-up tr…
