Ausgrid has contracted two specialist helicopters to carry out annual aerial inspections of the electricity network in bushfire prone parts of the Hunter, Central Coast and Sydney.
Ausgrid Chief Operating Officer, Trevor Armstrong, said this year the patrols began in the Upper Hunter.
“We saw this year’s bushfire danger period extended in parts of our network including the Upper Hunter, Muswellbrook and Singleton areas and we began our patrols in the areas of our network at greatest risk,” Mr Armstrong said.
“Safety is our highest priority and these patrols are a key part of our annual bushfire safety program to help identify and rectify any potential defects that might pose a bushfire risk.
“This year we have contracted two specialist helicopters to allow the patrols to be finished by the end of June, well before the start of the next bushfire season in September.”
The helicopter flights are the safest and most efficient way to inspect high-voltage powerlines and Ausgrid will remove or repair any hazards identified on our network during and soon after the patrols.
“The patrols reduce safety risks for our own people, because by using a helicopter, we can identify potentially dangerous hazards from above without putting our workers at risk.
The specialist crews will be using laser scanning equipment and taking high-resolution photographs to identify any hazards on our poles and wires and trees growing too close to powerlines.
“Using the photographs means our own workers don’t need to be placed in a position of having to examine damaged equipment up close,” Mr Armstrong said.
Crews will be in the air from about 7.30am to 5.30pm (weather permitting).
“The helicopters fly between 15 and 35km per hour and have been modified to allow for the quietest possible operation but they may fly low at times, which can startle livestock in rural areas,” Mr Armstrong said.
