VLF Hipot Instruments

Vlf hipot instruments is widely used in withstａnd voltage test. With its small size, light weight, easy to install advantages, more and more clients choose vlf hipot tester as the option of the ac hipot tester. It can do the dielectric strength test for the cables. Transformer, switchgear, circuit breaker, etc.

After more than ten years of continuous research and development, the production technology of Vlf hipot instruments has become more lightweight and intelligent; it has been upgraded from the previous series output maximum voltage of 80KV to a single-stage direct output of 0-90KV.

★Over-voltage protection: If the output exceeds the set limit of voltage, the instrument will shut-down to protect itself, the actuation time is less than 20ms.

★Over-current protection: it is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 20ms.

★A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside.
