الVLF hipot tester under Wuhan UHV can help many power workers conduct various power tests more conveniently.

The 0.1Hz VLF hipot tester has a wide range of application scenarios in power equipment testing, mainly including:

1. Voltage withstand test of power cables: Suitable for non-destructive insulation voltage withstand test of plastic power cables such as PE/XLPE, which are crucial for testing the insulation performance of the cables.

2. Testing of large high-voltage rotating electrical machines: used for voltage withstand testing of large generators and motors to ensure the integrity and reliability of their insulation systems.

3. Testing of power capacitors: Conduct AC withstand voltage tests on power capacitors to evaluate their insulation strength.

4. On site voltage withstand test: Due to its small size and light weight, the 0.1Hz VLF hipot tester is very suitable for outdoor on-site testing, making it convenient to test the equipment in different locations.

5. Preventive testing: Testing conducted in accordance with DLT 596-2021 "Preventive Testing Regulations for Power Equipment" to ensure that power equipment meets safety standards before operation.

6. Alternative power frequency withstand voltage test: In traditional power frequency withstand voltage tests, due to the need for large capacity test transformers or resonant transformers, the equipment is often bulky and inconvenient to carry. The 0.1Hz VLF withstand voltage test provides an alternative solution with the same equivalence, while significantly reducing the size and weight of the equipment.

7. Cable breakdown: In some cases, a 0.1Hz VLF hipot tester can be used for cable breakdown testing to help determine the fault point.

8. Insulation aging diagnosis: Conducting a 0.1Hz VLF withstand voltage test on power cables can help detect insulation defects and prevent future failures.
