Power surges and whole-house surge protectors

admin Wednesday September 13, 2023

Following a recent storm, my boss explained his Playstation was broken and said there was a power surge when power was restored. I was quite surprised since I always thought it was lightning itself which caused power surges.

This prompted me to read about power surges, which showed that while lightning is one source of surges, it is indeed far from the only one. But thankfully, I discovered not only these new risks, but a protection against surges I had never heard of: whole-house surge protectors (or surge arresters). I read a few interesting articles about surge and surge protectors. The one I'd recommend the most is the first:

Unfortunately, none of these gives convincing advice that one should use whole-house surge protectors. If you are aware of a cost-benefit analysis on the topic which compares average cost to how much losses using such devices prevents on average, please comment.
