Very Low Frequency High Voltage Generator

  VLF-90KV Hipot tester/high voltage generator

The withstand voltage test can be divided into ac withstand voltage test and dc withstand voltage test. The ac withstand voltage test can 

be divided into power frequency, frequency conversion and 0.1hz ultra-low frequency test technology, of which 0.1hz ultra-low frequency technology is 

the latest technology recommended by the current international electrotechnical commission.

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

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.
