Hello Everyone.
Looking for some opinions on testing XLPE cable. On 11KV XLPE cable we must do insulation tests with a VLF tester to avoid damaging the insulation. What about 600/100V low voltage 400 / 690V XLPE cable. Does a VLF tester need to be used for these cables as well. I have now phoned two cable manufacturers to ask their technical support this question and neither can verify whether this requires a VLF tester.
