The University of Strathclyde and the spin off company Elimpus, have developed ground based systems for locational detection of partial discharges using time of flight systems. One of these utilises an array of aerials contained within a van mounted “roof box”; a size compatible with the aerial separation that might be achieved between the skids of a typical Jet Ranger or Squirrel helicopter employed by DNOs for overhead line patrols. A small feasibility trial was undertaken to asses the viability of a larger IFI project that would entail development of equipment suitable for CAA flight certification.
The project will investigate the following objective:

Can ground source partial discharges in open terminal substations be reliably detected from a helicopter?
