MOV Arrestor failure naferna 11/21/2005
Looking for anyone with experience scanning MOV arrestors (in spetial 245 KV). I would like to know how a failure i determinated in this kind of arrestor. Is it a hot spot or is it like a heat distribution through the whole block?

I really apprecite any help

Do you have I/R images from different angle of views?

Actually, I have some pictures (jpg) from a laboratory test, but is this the only way that a failure is showed? and what about when the arrestor is working in overvoltage condition? How can i differenciate a normal heating due to the current operation from a heating produced by a failure?
