  • 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:

  • AC/DC dual purposes
  • Touch colour wide LCD
  • Easiest to use Fully automatic microcontroller
  • Built-in printer
  • True sine wave output
  • Real-time display of actual output waveform
  • Ergonomic, menu guided, large touch colour display.
  • 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
