Cable DAC Diagnostic Test Distribution

Professional testing and diagnosis for medium voltage cable

DAC voltage test and diagnostic measurements (PD and tan-d) provide a reliable detection of:

  • Poor installation
  • Failures due to inappropriate laying
  • Weak spots in cable accessories or
  • Deterioration of cable insulation due to aging

It allows much more than a simple go or no-go decision. DAC testing is an advanced maintenance tool which supports asset management and grid operation as well.

  • Sound withstand test method with test voltages representing operational stresses
  • Sensitive PD measurement and location in complete cable systems (insulation and accessories)
  • Assessment of cable aging status in comparison with other cables based on dissipation factor estimation

On-site DAC voltage test in combination with non-destructive PD and loss factor measurements is unique and fundamental for reliable service of newly installed, repaired or service-aged cable systems.
