HMCOP Very Low Frequency AC Hipot Test

VLF hipot test set is suitable fortesting cables, transformers,switchgear,rotating machinery,and otherelectrical apparatus.

Main Advantage of VLF hipot tester
1. Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.
2.Over-voltage/Over-current protection

product Description

VLF hipot tester combines modern advanced digital variable frequency technology and micro computer control together, therefore, VLF hipot tester can realize the full automatic voltage boost, step down, 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.

 



Features

1. Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.    

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

3. Over-current protection: VLF hipot test set 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.

4. 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.
