VLF Hipot Test Set

HENGFENG VLF hipot tester is a test set to test the condition of power cables and generators. High voltage VLF hipot instruments can realize the full automatic voltage rising, dropping, measurement and protection. Besides VLF testing, it can also perform DC testing.

The full electronic design ensures the small size and light weight.  

Color touch screen displays data and waveforms clearly. Test data can be stored to internal memory and printed by internal printer.

VLF hipot tester features:

1. VLF withstand test and DC test available

2. 7“ color touch screen display

3. True sine wave output

4. Real-time display of actual output waveform

5. Over voltage and current protect

6. Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz

7. Internal memory with time/date stamp

8. Internal thermal printer

9. Rugged and portable design
