Look out your window at the power pole, you'll see a transformer. That has breakers, differential relays, and other protections.

Substations have RTUs and SCADA systems that are constantly monitoring everything for faults. They have cool shit like oil breakers that can kill even the large inputs to the substation.

No, you don't. The protections go all the way back to the power generation site.
