Most electricians would choose NOT to re use wet cables,
Due mainly to legal liability issues,
But if you must ! Leave them out in the sun for at least a week.
whats the readout you are getting exactly?
If we are talking direct short like 0 ohms then that would be a first for me from moisture.
Sure ive had moisture give not ideal readings but ive never seen a direct short from it.
I'd check the connector first and make sure the connector "teeth" actually grabbed ahold of the armor and didnt grab the cable instead.
just curious, how are you testing it? at what voltage?
99% of the medium and high voltage failures I see are in the terminations. If there's any doubt, and it's at all possible, cut off the terms and re-test.
It's why I always have to laugh when we're asked to do a cable hipot on commissioning prior to the installation of the stress cones: If it's gonna fail, it's gonna fail because some screws up the terminations.
That said, while I've successfully dried a lot of equipment, never MV cable, and it'd be interesting to know if that's even possible?
We have had ends get wet cut off, splice on new piece, reterminate, test
