Ground Fault Neutralizer - A system minimizing the risk of fires, injuries and damages caused by power lines, enabling continuous safe power supply

Wildfires are a huge and still growing problem over the globe. Each year they take lives, destroys properties for billions and release an enormous amount of CO2 and other GHG into the atmosphere. A lot of the most catastrophic fires were started by power lines. In many places, climate change is creating conditions which electrical infrastructure is not ready to cope with.

The Ground Fault Neutralizer [GFN] is a protection system with unmatched performance for power lines. It minimizes the risk of fires, injuries and damages caused by power lines enabling to maintain safe power supply without any power outages, something all smart grids will demand. The GFN can neutralize power lines' single phase to ground faults (75 - 99% of all the faults in power networks) ultra-fast before they ignite a fire, where traditional protection is too slow and cannot prevent ignition. The GFN is proven technology, already protecting communities in Victoria, Australia.
