Abstract

The invention relates to a conductor monitoring apparatus 10 and a method 60 of monitoring an elongate conductor 12. The apparatus 10 may find application in measuring and monitoring the integrity of electrical power cables 12, fluid pipelines or railway tracks. In a preferred embodiment, the apparatus 10 is used to monitor power or telecommunications cables 12. The apparatus 10 includes a Time-Domain Reflectometer (TDR) 11 which is commonly used for measuring the integrity of and locating faults in electrical cables 12 by transmitting an electrical pulse along the cable 12 and measuring pulse reflections. The apparatus 10 further includes a memory module 50 for storing cable operating criteria, a control module 45 for comparing a measured cable integrity against the cable operating criteria, and a communication arrangement 19 for sending an alert message in response to the operating criteria of the cable 12 being violated. The invention aims to simply fault finding, identify illegal taps on power cables 12 and reduce cable theft.
