My post #33 was only too long for those with a short attention span.

As for conflating high and low frequencies, I’m no engineer, let alone an expert in the area of EMP. However, I carefully laid out my sources and let them speak for me.

The Carrington Event speaks for itself. So does Starfish Prime and Soviet Test #184. Is our electrical grid different than in 1859 or 1962? Yes, certainly. In some ways it is more vulnerable, in some ways less so. We are also FAR more dependent upon electrical and electronic devices than at any time in history, so any pulse (from whatever source) that would effect transformers, long lines OR electronic devices would have effects - perhaps devastating effects. What I cannot stand here (and in society in general) is the Normalcy Bias (which I incorrectly listed as “Confirmation bias” in my Post #33) that says that such effects are impossible - people need to get informed before shooting off their mouths (or keyboards).

The main point I would make is that the Soviet tests and Starfish Prime affected long lines. I agree that those would affect the modern grid. But you cannot compare that to hypothetical affects on electronic devices from high frequency EMP. First because high frequency EMP is not easy to produce and second because there are virtually no natural high frequency events (a galactic cosmic ray burst would be extremely rare).

OR electronic devices

Not "Or electronic devices", long lines only (meaning miles) and the connected transformers, and some electrical not on surge protectors or otherwise insulated.

Talk about vulnerable, at MCI we actually had a long haul fiber optic path taken out by a lightning strike. Our field techs found it and fully documented it. Our fiber had a copper conductor within the fiber sheath for technicians to use to communicate between the pull boxes. The technicians found that lightning hit a tree, arced through sand, and went into the copper conductor which heated like a fuse and crystallized the fibers in that section of fiber. The techs that found it figured no engineer would believe it so they dug up the fulgurite with photos to prove it.
