 Vlf High Voltage Tester Low Price AC Hipot Tester Vlf Cable Tester


 

• Vlf High Voltage Tester Low Price AC Hipot Tester 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.

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

High-voltage cable testing:
VLF high voltage generators can be used to test the insulation performance of cables in high-voltage electrical equipment. By applying low-frequency high voltage stress, potential problems in the cables such as small cracks or voids can be detected. This helps to identify and repair problems in advance, avoiding equipment failure or electrical breakdown.

Transformer testing:
VLF high voltage generators can also be used to test the insulation performance of transformers. By applying low-frequency high voltage stress, the internal and external insulation of transformers can be tested to ensure normal operation.

Switchgear testing:
 VLF high voltage generators can be used to test the insulation performance of switchgear, including circuit breakers, isolators, and grounding switches. This helps to identify potential insulation problems in advance, ensuring that the equipment can operate normally.

Rotating machinery testing:
VLF high voltage generators can also be used to test the insulation performance of rotating machinery such as motors, generators, and inverters. This helps to identify potential insulation problems in advance, ensuring that the rotating machinery can operate normally.
