Abstract
A lightweight and energetically autonomous device for real-time monitoring of overhead power lines, comprising:—an external housing (EMS1) provided, at opposed ends thereof, with a first (OP1) and a second (OP2) opening for a power line cable (HVC) traversing said external housing; a monitoring subsystem (B) for monitoring at least a mechanical parameter of said overhead power line; and—a communication subsystem (D) for transmitting monitoring information generated by said monitoring subsystem; characterized in that: an internal housing (EMS2) is provided within said external housing (EMS1), said power line cable (HVC) passing outside said internal housing (EMS2); said monitoring subsystem (B) is disposed within said internal housing (EMS2); said external (EMS1) and internal (EMS2) housings are both made of a conducting material in order to form electromagnetic shields; and said monitoring subsystem (B) comprises at least an oscillation sensor for detecting mechanical oscillations of said power line cable (HVC).
