Overhead cable e.g. overhead power transmission line, theft attempt detecting and warning device for central intervention center, has alarm detection, analyzing and teletransmission unit, and continuous wire fixed to cable and ground
The device has a robust case (20) including an alarm detection, analyzing and teletransmission units, impact sensors, and a verification unit to verify electrical continuity of an overhead cable e.g. overhead power transmission line (1). A continuous wire grounding the transmission line in its median zone is connected to secondary side of a transformer whose primary side is connected to a capacitor. The continuous wire has a wire length (21) fixed to the transmission line and a wire length (22) fixed to ground (10) via a tower (23).
