1. A system for the detection of discharges over high voltage power-line insulator strings of an electrical grid in which wires are deployed supported by towers, said device comprising:

  • at least one sensor unit associated with a non conducting wire of said grid;

    an array of at least one band cut-off filter (BCOF) receiving each signals from said at least one sensor unit;

    an analogue processor per each of said at least one BCOFs each of which having associated with a peak detector;

    analogue to digital converter (ADC) unit per each one of said analogue processors;

    a digital processor for calculating data received from each of said at least one of said ADCs;

    a communications link for sending data to a gateway of a network, andwherein said digital processor is adapted to send data processed based on output of said ADCs, to a server for further processing.
