Most power systems are built with a mix or clever automated systems that can self recover, along with backup dumb systems that can’t. This is done to ensure that if your smart stuff fails, you don’t end up seriously damaging something. Unfortunately the dumb stuff pretty much always has to be reset manually. Usually because the dumb stuff tripping means you’ve encountered a scenario that no one anticipated, you really want someone to double check that nothing got damaged before the safety tripped. It’s a little like a database starting up and discovering that part of its Write-Ahead-Log is corrupt. You really want a human to go in there and see what happened, rather than just ignoring the damage, plowing on and loosing data.
