China 0.1Hz Vlf AC DC High Voltage Hipot Tester for Power Cable Testing

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









VLF Advantages:
1. Safe Optical isolation technology,
2. Easiest to use Fully automatic microcontroller
3. H/L voltage closed loop negative feedback control
4. Built-in printer
5. Built-in protective resistors
6. True sine wave output
7. Real-time display of actual output waveform
8. Ergonomic, menu guided, large backlit LCD
9. Storage of test results for later retrieval and print.
10. Over voltage and current protected
11. Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz, 0.01Hz
(0.01Hz for optional)
12. Data of current, voltage and waveform directly sampled at HV side.
13. AC testing does not degrade good cable insulation
14. Harmful space charges are not injected into the cable insulation
15. No traveling waves are generated during testing
16. Rugged and reliable design less prone to failure from transients
17. Invatation Patent
18. Portable, 1 control unit and 1 booster or 2 boosters (≥ 60KV set)
19. CE mark.
Safety Features
1. Short circuit protected.
2. Status display of all important safety functions and messages.
3. Safe, easy to use operation with emergency off and key switch lock-out.
4. Fully integrated discharge circuit to safely ground the DUT after testing.
5. Zero start interlock.
6. Zero voltage switching.
