Best Partners in Maintenance of Electric Power Facilities
Cable Fault Locator System
Applied to underground cable
Feature Fast and accurate cable repair is necessary with cable fault detection
TDR pulse indicates the fault point of disconnected cable
TDR cannot indicate high voltage fault reverberation
With pulse reverberation, it automatically measures distance of fault point
Pinpoint the exact location with electromagnetic field signal & sound signal

Outline
  • - Fast and accurate cable repair is necessary with cable fault detection
  • - TDR pulse indicates the fault point of disconnected cable
  • - TDR cannot indicate high voltage fault reverberation
  • - With pulse reverberation, it automatically measures distance of fault point
  • - Pinpoint the exact location with electromagnetic field signal & sound signal

Applicable
  • - HV-Module SPG32 (withstand voltage, instant high voltage, stabilize ARC)
  • - TDR Teleflex SX portable
  • - Additional Digiphone + (fault pinpoint)

Model
  • - Lots of different type of model, Surgeflex 32, Mobile fault point machine and test system that can be installed on the van. (KEPCO is in possession of R30 Test Van from Seba)

 

Fault point detection method

Level 1: Pre-location
  • - After withstanding voltage test (different from the model)
  • - Send surge DC voltage on the high resistance fault point > low resistance
  • - Flash over on fault point
  • - Measure pulse reverberation with TDR for Digitalizing the distance to the fault point (compare with high voltage pressure of TDR pulse)

* Seba equipment function: ARM (Arc reflection method), decay method, ICE impulse current method, burning, etc.

Level 2: Pin-point location (using Digiphone+)
  • - Calculate the distance from fault point and detect acoustic or other magnetic signal for accurate fault pin-point
