Powercor is continuing to test new drone technology to inspect powerlines and pole-tops faster and in
greater detail than ever before, in flights over the Charlton and surrounding areas this week.
Remotely piloted drones are making the inspections along 20 kilometres of powerlines in the
Charlton, Wedderburn and Bridgewater area along the Calder Highway and along the main supply
line from Bendigo on 23 and 24 August, weather permitting.
The work, which will occur during daylight hours on both days, is in addition to Powercor’s ongoing
continuous program of asset inspections, which are also being conducted by crews in vehicles, on
foot and by helicopter.
A specialist team is trialling the Matrice 300 RTK – a powerful industrial drone platform with an
advanced flight controller system, six-directional sensing, real-time video transmission, thermal
imaging and obstacle-detection systems.
This trial follows a trial of a similar technology near Ballarat last month and in the Otways last
September, with results from the new Charlton trial to inform whether the technology is suitable for
inclusion in Powercor’s continuous inspection program.
Powercor Head of Network Asset Management John Mifsud said the drone inspections would cover a
large area, quickly, with high-definition cameras used to capture the condition of powerlines quickly
“This trial is about finding new ways to keep our network operating safely and reliably,” Mr Mifsud
“While these drones won’t replace our existing inspection methods, we’re looking at whether they
have a permanent role in our program in the future.”
Powercor manages its network of almost 90,000km of powerline and 588,000 poles through a
rigorous inspection and maintenance program, on top of a network-wide vegetation management
program clearing trees and shrubs well away from powerlines.
