After withstand voltage test apply DC voltage to cable (high resistance → low resistance)
Store the distance from the point of failure to the point of failure with Flash Over Concurrent TDR
Generate a pulse signal to confirm the location of the fault point by sound detection
Used With Fault Point Pin Point Detector

fault spot detection method
icon02.png Step 1 : Pre-location
  • After withstand voltage test (according to the model, the applicable voltage is different)
  • Apply surge DC voltage to cable: high resistance failure point → low resistance
  • Let the flash over at the failure point, At that moment, TDR digitizes the distance to the pulse echo measurement failure point (compare TDR waveforms
  • before and after high voltage applications).

* Seba Equipment Function: ARM (Arc Reflection Method) Decay Method, ICE Impulse Current Method, Burning, etc.

  • Measure the distance to the failure point, detect sound and magnetic signals, and pin-point the accuracy failure point.
