Webb8 apr. 2015 · DC Hipot can be destructive on XLPE cable, however all the test standards (ICEA, NETA, ANSI, IEEE) that have addressed this only refer to service aged (>5 years) cable, no standard for new installations as far as I know have been revised to reflect warnings on new cable for DC hipot tests. WebbA VLF hipot is an AC output tester with an output frequency of 0.1 Hz or lower rather than 50/60 Hz. Although the frequency is very low, it is an alternating current with polarity reversals every half cycle. At 0.1 Hz output, it takes 600 times less current and power to apply an AC voltage to a capacitive load.
