There is a correlation between RF discharges and network faults on overhead lines with the RF signal being picked up by a radio antenna up to 70km away. If antennae are spread across the network, a mesh is formed in a similar manner to the GSM network. If a fault can be accurately clocked, triangulation can be used from a number of base stations to give an approximate geographic location (within 300m) and linked to GIS / SCADA data to give a more accurate fault location.
Applied research, and follow up installation of a system to triangulate fault locations on overhead lines from the high frequency radio wave signatures produced from an arcing fault.
