VLF Cable testing for cables rated to 35kV VERY LOW FREQUENCY AC HIPOT The High Voltage, Inc. VLF-6022CM(F) with its 62 kVac peak output, is suitable for all testing of 35 kV cable per IEEE 400.2-2013. Its high load capacity enables it to test up to approximately 15 miles of cable...
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. These failures ...
