Helicopter patrols power lines for bushfire prevention
The Peninsula will be subject to helicopter bushfire prevention patrol inspecting power lines as part of an exercise occurring in the Gosford area on June 27-29.
The helicopters are expected to be in the air from 7:30am to 5:30 pm, weather permitting, flying between 25 and 40 kilometres per hour, often at low altitudes.
The patrol are will extend as far north as Kariong, Niagara Park and Foresters Beach and as far south as Patonga.
They will be conducted by contractors for electricity distributor Ausgrid.
The work will be done in conjunction with the NSW Rural Fire Service, local councils and community groups and will inspect power lines, poles and other equipment in bushfire-prone areas.
The helicopter crews use radar imaging equipment and high resolution photography to identify potential bushfire hazards, according to Ausgrid.
"The radar sends and records 300,000 pulses every second to create a three-dimensional representation of the network and is capable of identifying branch heights with an accuracy of within two centimetres."
Over the course of three months, the patrols will cover an area including the Hunter Valley, Central Coast and Sydney.
