VLF 0.1Hz 40kV Very Low Frequency AC Hipot Test Set for Power Cable

 

Product Name:

Very Low Frequency Tester VLF-40

 

Equipment Description:

The VLF testers (Generator) are suitable for Testing cables, transformers, switchgear,Rotating machinery, and 

other electrical apparatus.

 

Main Functions:

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
