VLF Very Low Frequency High Voltage Generator for High Voltage Cable Test

Introduction:

 

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

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

 

 

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.
