VLF Hipot tester

Product Description

The VLF testers (Generator) are suitable for testing cables, Transformers, switchgear, rotating machinery, and other electrical apparatus.

How to use VLF Hipot Tester?

VLF hipot is simple micro controller based tester. The load is connected to the HV output and ground return of the VLF unit. Set the test voltage, maximum current, time and start. The test voltage is applied for the set duration. A backlit LCD displays the status and wave form. Hipot automatically cuts off the test voltage once the test is over. The load under test either holds the voltage and passes or fails. It is a go/no go test. Print the results on the in-built printer.

VLF 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.*5Hz, 0.*2 Hz
9. Data of current, voltage and waveform directly sampled at HV side.
*0. AC testing does not degrade good cable insulation
*1. Harmful space charges are not injected into the cable insulation
*2. No traveling waves are generated during testing
*3. 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.
