Honestly even in "developed countries" it's not worth blindly trusting that the power in your house/building is clean. It's cheap and easy enough to just put any expensive hardware on a UPS rather than speculating what's going on behind the walls.
I work on embedded systems. I can often see whether my A/C or other appliances are running on my oscilloscope signals. They often affect the output of USB power supplies.
Eh, if these surges are rare enough, then you are statistical better off just risking your 'expensive' hardware to a one in a trillion possibility rather than spending money on gear you don't need.
Do you live in a bunker to protect against artillery shells?
Doesn't even sound like a developed country to me. Is that the US or something?
