VLF High VoltageTester

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 use Fully automatic microcontroller
  • * Built-in printer
  • * True sine wave output
  • * Real-time display of actual output waveform
  • * Ergonomic, menu guided, large 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
