VLF High voltage Tester

VLF High voltage Tester VLF High voltage Tester VLF High voltage Tester VLF High voltage Tester
Product name:VLF High voltage Tester
Item:VLF-80
Details:
Purposes:

AC Testing of cables and electrical apparatus
is now easierthan ever if using our VLF High Voltage Tester !
 
VLF testersare suitable for testing cables, transformers,switchgear,rotating machinery, and other electrical apparatus.
 
VLF Advantage: 

1.Easiest to use Fully automatic microcontroller
    *  2.Built-in printer
    *  3.True sine wave output
    *  4.Real-time display of actual output waveform
    *  5.Ergonomic, menu guided, large backlit LCD
    *  6.Storage of test results for later retrieval and print.
    *  7.Over voltage and current protected
    *  8.Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz, 0.01Hz
    *  9.Data of current, voltage and waveform directly sampled at HV side.
    *  10.AC testing does not degrade good cable insulation
    *  11.Harmful space charges are not injected into the cable insulation
    *  12.No traveling waves are generated during testing
    *  13.Rugged and reliable design less prone to failure from transients
