Product Details

A 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.

VLF HV hipot tester can mainly be used to perform AC voltage withstand tests to cables, motors, generators, and other highly capacitive loads using test equipment that is portable, easier to use, and more economical than conventional methods. These tests can now be conducted at 0.1 Hz. or lower with test voltages of 1 Uo – 3 Uo, or 1 – 3 x normal operating voltage.

A major advantage of VLF generator is that when comparing the voltage application at power frequency at 50/60 Hz, there is a 500x/600x lower power and current requirement when testing the same cable at the same voltage level. Hence the size of the generator required to produce high voltages can be significantly reduced, allowing for more portability and accessibility of the equipment in field testing environments.

FSVLF combines modern advanced digital variable frequency technology and micro computer control together; therefore, it can realize the full automatic voltage boost, stepdown, measurement and protection as well as the manual intervention in the process of automatic voltage boost. The full electronic design ensures the small size and light weight. The big LCD screen ensures the clear and visual display, and can display the output wave form. The printer outputs test reports.

The regular models are FSVLF-30kV, FSVLF-50kV and FSVLF-80kV.
