As a kid, thunderstorms commonly knocked out the grid. Now as an adult I've rarely seen the power go out (It usually happens due to someone ramming a power line with their car).
- pixl97 3y agoSeemingly in these threads a lot of people don't understand solar storms at all. When lighting hits you get a few microsecond burst of a whole lot of power that gets dumped to ground. Your grounding will get very hot from this, but typically you're not getting hit constantly all day in the same grounding location. Now imagine this. You start getting excess power to the point it's starting to drive primary movers on the grid. You disconnect them because you don't want bad shit happening to your generators. But your grid is still generating power, in some places an awful lot of power that is acting more like DC rather than AC. So you're going to dump this to ground right? Have you ever welded? Because when you dump power to ground it's still power and it makes things hot. Unless you build in massive heatsinks you're going to have a problem.
