Abstract :
Power circuit temperature monitoring based on distributed temperature sensing (DTS) is used worldwide. Applications include real time temperature monitoring of high voltage power cables, including direct buried, duct bank, submarine and distribution cable installations. The benefits of this technology, as applied to power cable monitoring, are outlined. International trends towards the specification of real time dynamic rating systems, based on IEC 60287, are described. Also included is the application of DTS to power cable tunnels, where in addition to power cable monitoring, tunnel ambient temperature and fire detection are achieved within a single system. Applications of the technology to overhead lines, substations, and other plant are described.
