Basically, the technology uses something known as power diverter - Rapid Earth Fault Current Limiters (REFCLs)—react to the surge of current unleashed when a power line strikes the ground or is struck by a tree. When this happens on one of Victoria’s 22-kilovolt distribution circuits, the REFCL instantly begins collapsing the faulted line’s voltage toward 100 volts, and can get there in as few as 40 milliseconds (ms). “If it can do it within 85 ms, you won’t get fires,” he says.
