1. An overhead power line monitoring device, comprising:

  • an external housing (EMS1) provided, at opposed ends thereof, with a first and a second opening for a power line cable traversing said external housing;

    a monitoring subsystem for monitoring at least a mechanical parameter of said overhead power line; and

    a communication subsystem for transmitting monitoring information generated by said monitoring subsystem;

    characterized in that;

    an internal housing is provided within said external housing (EMS1), said power line cable passing outside said internal housing (EMS2);

    said monitoring subsystem is disposed within said internal housing;

    said external and internal housings are both made of a conducting material in order to form electromagnetic shields; and

    said monitoring subsystem comprises at least an oscillation sensor for detecting mechanical oscillations of said power line cable.
