There are many well established cable fault location techniques, particularly for buried underground cables

Successful cable fault location depends to a great extent on applying the appropriate technique or combination of techniques

Methods for locating cable faults require competent engineers and service providers

Guidance is required for engineers on the correct application of the various techniques available


The TB 773 covers the most common methods for fault location, in addition new and emerging techniques are also included. Chapters on emergency planning is also part of the brochure. Methods covered are:

  • Time Domain Reflectometry / Frequency Domain Reflectometry
  • Bridge methods
  • Fibre optic methods (OTDR, Vibration, Acoustic, Temperature)
  • Acoustic
  • Step Voltage
  • Magnetic field


The downloaded document includes on the first page the link to the video, and the complete presentation in PDF format.
