Cable Fault Locators

Features and Benefits

With its 20 kV output, the CDS-2010U(F) is good for fault locating cables rated up to 35 kV with a line to ground voltage of 20 kV. The high burn current of 400 mA can be used to condition a fault to reduce its arc overvoltage to permit thumping at a lower and less damaging voltage level, still at full energy. The CDS-2010U can thump a cable at just 5 kV while delivering 1000 joules. Find your fault without creating the next one.


  • Constant energy, three output voltage taps at full energy
  • Fully variable hipot output on all voltage taps
  • TDR-ready, arc-reflection and current pulse methods
  • Built in high voltage coupler for TDR interconnect
  • Variable discharge rate
  • High burn currents
  • Portable, hand truck mounted
