The Distributed Temperature Sensing (DTS) online surveillance of a 220 kV power cable system in Xiamen Power Utility, China helps preventing a potentially serious large-scale high voltage cable fault.
Following the DTS system alarm indication the maintenance staff of the power utility was able to discover a grounding problem in one cross bonding box. As the DTS system indicated this emergency at early stages and precise in location a blackout or a repair de-energising procedure could be 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.
