LA Megger Test
LA Megger Test
(OP)
Is meggering a lightning arrestor really a good test to show if the LA is good or not?
I usually test the 8KV and above Las at 5Kv and if I am reading more than 1000MG then I assume its good reading; however I am told that intermediate La’s are resetting themselves and meggering a LA is not a true test to show if they are good or bad!
I appreciate any comment on this subject

Hope this helps.

By the way, I checked hubble website and there is nothing mentioned about the megger test for LA

Doble tests would show you watt's loss (basically, how good of an insulator the LA is), and a HiPot can be used to find the strike voltage, but the manufacturers seem to say that the factory tests are hardly ever reproducable in field conditions.
My two cents.
