"He is attempting to identify a problem, not commission a cable"
A DC hipot would be fine if he was commisioning a cable, A PD or Tan delta test is a condition assesment test.
"as I said before, an ohm meter"
You really think putting 5-7V across 15kV insulation will tell you anything but "O.L."???? That wont even charge the insulation. A DAR test with a 5000V megger may provide some useful info if you want a quick easy test.
"He may want to consider an AC test as opposed to your DC"
Thats what I have saying all along.
