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
