As part of our Bushfire Risk Management Strategy we are working with the NSW Rural Fire Service, local councils and community groups to inspect powerlines, poles and other equipment in bushfire-prone areas.
Ausgrid engages specialist contractors to conduct bushfire safety helicopter patrols in parts of The Hunter, Newcastle, Central Coast and Sydney looking for hazards. The helicopter crews use radar imaging equipment and high resolution photography to identify potential bushfire hazards. The radar sends and records 300,000 pulses every second to create a three-dimensional representation of the network and is capable identifying branch heights with an accuracy of within two centimetres.
Example of the high resolution photographs provided by the LiDAR patrols.
