Cross Bonding Earthing Fault Detected by Distributed Temperature Sensing Surveillance in China

The Distributed Temperature Sensing (DTS) online surveillance of a 220-kV power cable system in Xiamen Power Utility, China, helped prevent a potentially serious large-scale high voltage cable fault.

Following the DTS system alarm, the maintenance staff of the power utility was able to discover a grounding problem in one cross bonding box. Because the DTS system indicated this emergency at early stages and was precise in the location, a blackout or a repair de-energizing procedure was successfully prevented.

This success story for online power cable temperature monitoring was presented at the recent Jicable conference, the 8th International Conference on Power Insulated Cables.
