  1. University of Strathclyde Department of Electronic and Electrical Engineering 204, George Street, Glasgow G1 1XW, UK URL: www.eee.strath.ac.uk Email: Fault-Locator@eee.strath.ac.uk Tel: +44 (0)141 548 2587 This project has received assistance from the Proof of Concept Fund managed by Scottish Enterprise.  The Proof of Concept Fund supports the pre-commercialisation of leading-edge technologies emerging from Scotland's universities, research institutes and NHS Trusts.

  2. Automatic Fault LocationFor Underground Distribution Network SIEW Wah Hoon SORAGHAN John HOSABETTU Nandaraj STEWART Martin

  3. The Challenges • Reflections from single phase and 3 phase tee-offs often lead to misinterpretations of actual fault. • High level of interpretation skills are required to analyse TDR signals.

  4. Network Schematic

  5. TDR Signals

  6. The Technology TDR Signal Acquisition Cable Characterisation Signal Processing Fault Location Fault Distance Display

  7. Difference Error Vs. New Method

  8. Table of Performance

  9. Conclusions Strathclyde’s IFL Technology promises: Reliable fault location No requirement for skilled personnel on TDR interpretation T-joint transparency
