“How can we isolate a section of the grid when a fault is detected?”

 

Faults happen in grids all the time. Whether if its from a branch falling on a transmission line or an over surge of current. However, if these faults are not contained, then it can spread to the rest of the system and cause a cascading failure. To prevent this from happening, one proactive method is to isolate a portion of the grid with the failure. This can be accomplished through appliances called Grid Sectionalizers, which can detect when too much current is going the wires they’re attached to. Grid sectionalizers are being deployed by PG&E in Northern California to build resilience against wildfires.
