Some of Victoria's worst bushfires have been started by power lines. So, power distribution companies have installed devices that limit the energy flowing to the fault to cut the fire risk. However, in networks equipped with these devices, communities might experience power outages for hours while network operators attempt to track down a fault along tens of kilometres of power line. "In trials in China and Switzerland we demonstrated that our technology can find the fault location to within hundreds of metres in a few minutes, instead of hours or days," says Monash University engineering researcher, Dr Reza Razzaghi.
