Details

Very Low Frequency AC Hipot Test Set is the direct method to identify the insulation strength of XLPE power cables. It uses 0.1Hz very lo w frequency technology, the capacity is only 1/500 of power frequency. With small size and light weight, it is suitable to make withstand voltage test for large capacitance equipment such as power cables,power capacitors,large and medium generators/motors.

Function:
1. Over-voltage protection function.
2. Over-current protection function.
3. Built-in protective resistor.
4. Sampling from high voltage side, data is morereal
5. With high and low voltage double protection ,protective action time is less than 20ms.

It realizes the fully automatic voltage boost, step-down, measurement and protection as well as the manual intervention in the process of automatic voltage boost.

Closed-loop negative feedback circuit is adopted. No capacity rising during outputting.
