Whats the best technique to use to locate a sheath fault for a cable thats put inside of a conduit. The Insulation resistance between the metal screen and earth fails and reads a low value of 200kOhm to 500kOhm. The cable not being in direct contact with earth ground soil makes it difficult to locate using conventional fault locating methods, therefore does anybody have any experience with this special situation?
" The Insulation resistance between the metal screen and earth fails and reads a low value of 200kOhm to 500kOhm "
That doesn't sound like a short circuit. Could be prolonged water penetration while enclosed in conduit. or maybe filters/circuits/switches still connected....
