By making substantial upgrades to Victoria’s high voltage powerline network, the state is leading the way in reducing the threat of bushfires started by powerlines. The range of powerline safety measures being undertaken include:
- Replacing bare-wire, overhead powerlines in bushfire-prone areas with safer underground or insulated powerlines as part of the Powerline Replacement Fund;
- Installing enhanced fault detection and suppression control on single wire earth return (SWER) lines on high-fire days using more sensitive, remotely controlled Automatic Circuit Reclosers;
- Mandating advanced network protection standards to reduce the risk of bushfires on over half of the state's three-wire, 22kV high voltage powerlines by installing Rapid Earth Fault Current Limiters at 45 zone substations.
