ELI5 what happens when lightning strikes and the power goes out for a minute or two then comes back on.

It obviously affects the power grid but how does it get fixed so quickly.

There are grid protection systems, basically big versions of the circuit breakers you have at home, that can be tripped by a lightning strike or other events during a storm.

These big circuit breakers are smart enough to check to see whether there is still a problem (tree on a line or something), or if the problem has gone away (if nothing was damaged by the lightning). If there is no problem anymore, the breakers will close themselves automatically.
