VLF AC Hipot Tester ,AC Voltage Booster
A VLF hipot testeris just an AC output source but with an output frequency of 0.1 Hz or lower rather than 50/60Hz. Although
the frequency is very low, it is still an alternating current with polarity reversals every half cycle. At 0.1 Hz output, rather than 60Hz, it takes 600 times less current and power to apply an AC voltage to a capacitive load, like a long cable.
There is no better way to verify the AC integrity of a cable than to hipot it with AC voltage.
VLF hipots testersare used to provide a go/no-go, or pass/fail, voltage withstand test. It can also be used as the voltage source for diagnostic cable testing. Contact HVI for more on Tan Delta and Partial Discharge measurement accessories.
VLF AC Hipot Tester is applied in power cable and generator insulation test in power system
