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.
