Product Description

China Export  Portable 0.1Hz 80kv High Voltage Vlf Very Low Frequency AC Insulatio Hipot Tester for Cable/ HV measuring instruments/ high voltage Electrical Test Equipment

VLF (Very Low Frequency) hipot Testers are suitable for testing power cables, transformers, switchgear, rotating machinery and other electrical apparatus.


VLF hipot teser Advantages:

1. Easiest to use Fully automatic microcontroller
2. Built-in printer
3. True sine wave output
4. Real-time display of actual output waveform
5. Ergonomic, menu guided, large backlit LCD
6. Storage of test results for later retrieval and print.
7. Over voltage and current protected
8. Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz
9. Data of current, voltage and waveform directly sampled at HV side.
10. AC testing does not degrade good cable insulation
11. Harmful space charges are not injected into the cable insulation
12. No traveling waves are generated during testing
13. Rugged and reliable design less prone to failure from transients
