Digital Megger Connections 'G'
Digital Megger Connections 'G'
(OP)
Hi, I have a Digital megger and can't recall the purpose or how to use the 'G'for ground connection on the meter.
The other sockets on the meter are L, E2 and E used for 500 and 1000 volts. L being common.
Any instruction on how to use and understand this 'G' socket would be appreciated, as the manual relates to it as the 'protection circle'. But I don't know what that means.

RE: Digital Megger Connections 'G'
You have described the guard terminal. Connected to a metallic ring placed over the outer surface of an apparatus bushing, it will cancel/offset leakage current over the bushing surface, or in a multiconductor cable, tied to one or more conductors to “exclude” them from influencing the measurement. Biddle/AVO/Meggger sells a booklet, “A Stitch in Time,” or AEMC has a terse version www.aemc.com/techinfo/techworkbooks/megohmmeters/t...
