Yup, we take surge protection seriously here.
In my previous life as a Physical Planning Rep at IBM, we did not have
the luxury of telling our customers to unplug everything every time
there was a thunderstorm (pretty much every day in the summer) so we
needed to design systems that mitigated the damage. We got pretty good
at it. It can be summed up by saying you trap the surge and shunt it
into the ground. You use MOVs and chokes along with a lot of copper.
