How hipot tester works
Web30 dec. 2024 · The test is to ensure that they work correctly by measuring the hi-pot current. If they fail, they can self destruct but the current used is very limited. NOTE: cables that have been hi-pot tested should be discharged before being used. Web20 jun. 2024 · Testing of cables was traditionally conducted with DC voltages in the past, which was also known as DC hipoting. Once polymeric cables (XLPE, EPR, etc.) were introduced into the electric grid and readily being tested with DC, a considerable rise in premature failures occurred.
