Product Description

Description Sandi VLF stands for Very Low Frequency. A Sandi VLF is an AC output high voltage instrument. Sandi VLF products provide sinusoidal AC voltage but at 0.1Hz - 0.*2 Hz, compared to the *0/*0Hz output of conventional AC test sets. It is still an AC voltage with sinusoidal polarity reversals every half cycle. The Sandi VLF instrument is used to provide a simple go/no-go, or pass/fail withstand test. Also, Sandi VLF instruments can be used as the voltage source for performing off-line Partial Discharge testing. 
  Application Sandi VLF testing is used for any application requiring AC testing of high capacitance loads. The major application is for testing solid dielectric cable, followed by testing large rotating machinery, and occasionally for testing large insulators, arrestors, and the like.
Even if a utility doesn’t adopt Sandi VLF for widespread cable testing, one of the best reasons to use VLF is to check installation quality and accessories, like splices. Many failures are due to damage during installation, improper workmanship, and/or insulation damage caused by excessive voltage fault locating - thumping. At the very least, every newly installed or repaired cable should be Sandi VLF tested before re-energizing.
  Benefits of Sandi VLF  

  • Portable and affordable.
  • All models feature is true sine wave output.
  • Waveform is independent of load capacitance between 0.*1mF and maximum load.
  • Highest load ratings available.
  • Highest voltage models available.
  • Simple and easy operation.
  • 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.
  • No polarization effects as with DC.
  • Breakdown detection.
  • Reporting
  • Display: The 7 'capacitive touch screen, the screen displays real-time measurement data and the output waveform.
  • Comprehensive protection: high, low pressure side of the overvoltage and over-current protection, rapid response action (action time *0ms).
  • Small size, light weight: very conducive to outdoor work.
  • Communication interface: USB2.0.
