Cable Fault Locators (Thumpers)

CDS Series Controlled Energy Fault Locators

These are self contained semi-portable test sets for testing and fault locating in primary cable systems

  • Three output taps provide maximum thump energy at each of three selectable output voltages
  • All models include a Hipot/Burn output. Advantages are:
    • Apply voltage to verify fault and ID the bad cable
    • Determine breakdown voltage to select proper output voltage tap
    • Burn/condition the fault to permit lower voltage less damaging thumping
    • Hipot the cable after repair
  • Remote TDR/Radar design
    • TDR and thumper can be used separately
    • Easier repair/replace of either component
  • Internal Arc Reflection Filter is compatible with other radar units on the market
  • Three Models:
    • CDS2010U 0-5/10/20 kV output. 1000J at all taps
    • CDS3616U 0-9/18/36 kV output. 1600J at all taps
    • CDS3626U 0-9/18/36 kV output. 3200J at all taps
