System and method for assessing faulty power-line insulator strings

摘要

A system for the detection of discharges over high voltage power-line insulator strings of an electrical grid. A sensor unit is deployed on a non conducting cable of the grid. The sensor feeds an array of band cut-off filters receiving each signals from said at least one sensor unit. An analogue processor is associated with each of the band cut-off filters associated each with a current peak detector. An ADC unit is associated with each one of said analogue processors. In addition a digital processor is provided for calculating data received from each one of the ADCs and one radio transmitter unit sends data to a gateway of a network. A digital processor is adapted to send data processed based on the output of the ADCs, to the radio transmitter for conveying the data to processor associated with a WAN.

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, and wherein said digital processor is adapted to send data processed based on output of said ADCs, to a server for further processing.
