First time meggering conductors in PVC. We have a meggering requirement for final completion and I'm not sure we can get any useful information about the integrity of the insulation if there is no metal conduit for the megger voltage to leak into.
I have seen some suggestions that we should megger cable to cable in PVC (we have two conductors per conduit) but it seems that unless both cables have a nick near each other that wouldn't detect anything either.
So, is there any test to accurately verify the integrity of the insulation of a conductor in non-metallic raceway without filling it with water or something?
Thanks
