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
• 60 mins continuous working
• 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
