Yes, the initial surge. And then...?

?? Can't figure out that one. OV is OV, and the avionics pay no mind as
to the original cause : zap all the same.
It is a good thing to try to fool proof an architecture. But OV
protection is there to protect against even things that should not happen.
You'd be surprised at the number of things that happen in aviation, and
yet should not happen : empty tanks, wheels up landings, popped
breakers, fried radios, engine failures, accidents...
You may wish to have a peek at www.aeroelectric.com. The load dump
scenario has been covered extensively.
