Power cables testing
Power cables testing
(OP)
I have a 5 kV & 15KV new power cable sets to porform HiPot testing and may question is if 2(nominal voltage) + 1 is enough for insulation test on each cable.
Thank you for any support about that.

We are talking about completly NEW cables - Tan delta is not predicative in this case. We can expect strict cable manufacturer test in the factory, if the sheath test is ok we can expect good insulation and only mounting faults (joints, terminations)possible. Then the best is PD testing. For those who rely on withstand testing is AC or VLF test suitable too - but ONLY as an additional test to PD+sheath testing!Remember this kind of test can be destructive, probably will give you no result if done after successful PD+sheath test. The situation is slightly different with in operation or very old cables.

Agreed, but you can establish some good baseline data for future assesment.
For PD testing, these guys are very good, Don is well known in North America as a PD guru.
