1. EMP induced damage primarily a concern for devices connected to long, horizontally strung conductors (ex; power lines)
2. All power distribution systems are fused. There’s fuses all over them, from your residential tap transformer to every major connection all the way back to the sub-station and then again to the generator.
3. EMP is real, but it’s potential for damage is wildly exaggerated.
Yes. If we hear an air raid warning, it might be a good idea to unplug electronic appliances including network cables.

Did you read the EPRI paper by Rabinowitz I posted to RFEngineer further up-thread?
You would have seen those points discussed ...
BTW, re: “There’s fuses all over them, from your residential tap transformer to every major connection all the way back to the sub-station and then again to the generator.”
Uh, no. Not quite. Sure, “expulsion” fuses on the primary side of your local ‘pole pig’, but that’s about it as far as “fuses” go.
Now, go view one of the videos on substation design and layout I posted above. You obviously are unfamiliar with the industry term protective relaying. It involves current “sensing” relays (a holdover term from the early days) AND circuit breakers. Substations are chock full of them. That along with CTs and PTs (or VTs if you prefer).
BUT there is a LOT more to that, involving time delays and “distance” and phase sensing. ALL computer (PLC) driven.
Again - CHECK OUT ONE OF THOSE INFORMATIVE VIDEOS and become educated on this technology.
