Abstract
Energy distribution companies have experienced an increase in catastrophic failures in power systems due to the theft of grounding cable. The objective of this study is to develop an innovative technology which is able to detect the absence of grounding cable in medium and high voltage systems. The wireless technology developed communicates periodically with the system's central control unit to ensure reliable and safe operation of the installation. Because it is not economically profitable to modify power systems’ infrastructure, this novel sensor is non-intrusive as well as self-supplying. Based on the validation step's results, we conclude that the sensor is ready to be tested in smart grid equipment to monitor the state of grounding cables.
