  • Product description: VLF-80 gives 80KV peak output
  • INQUIRY

Purposes:

AC Testing of cables and electrical apparatus is now easier than ever if using our VLF High Voltage Tester !

VLF testers are suitable for testing cables, transformers, switchgear,rotating machinery, and other electrical apparatus.


VLF Advantage:

-Easiest to see fully automatic micro-controller

-Built-in printer

-True sine wave output

-Real-time display of actual output waveform

-Ergonomic, menu guided, large touch colour backlit LCD

-Storage of test results for later retrieval and print.

-Over voltage and current protected

-Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz, 0.01Hz

-Data of current, voltage and waveform directly sampled at HV side.

-AC testing does not degrade good cable insulation

-Harmful space charges are not injected into the cable insulation

-No traveling waves are generated during testing

-Rugged and reliable design less prone to failure from transients
