Product Description

High Quality Vlf Very Low Frequency High Voltage Tester AC Hipot Tester

Product Description

The ultra-low frequency insulation withstand voltage test is actually an alternative to the power frequency withstand voltage test. When conducting power frequency withstand voltage tests on large generators, cables and other test products, since their insulation layers present a large capacitance, a large-capacity test transformer or resonant transformer is required. This not only makes the equipment bulky and expensive, but also very inconvenient to use. Years of theory and practice at home and abroad have proved that replacing the power frequency withstand voltage test with a 0.1Hz ultra-low frequency withstand voltage test can not only have the same equivalence, but also greatly reduce the size of the equipment, greatly reduce the weight, and be simple to operate, which has more advantages than the power frequency test.

 

Product Features

 

1. The high-voltage side can directly sample current, voltage, and waveform data, and the data is true and accurate.
2. Multiple protections: overvoltage protection, overcurrent protection; when the current on the low-voltage side exceeds the rated current, the instrument automatically shuts down for protection, and the action time is less than 20ms.
3. The booster is designed with a high-voltage output protection resistor, and no external protection resistor is required.
4. It can realize fully automatic boosting, voltage reduction, measurement, and protection, and can also perform manual intervention during the automatic boosting process.
5. All-electronic design, small size, and light weight.
6. The large-screen LCD display is clear and intuitive, and can display the output waveform and print the test report.

Applications

 

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.
