As owner of the book “One Second After” and having been a multiple certified and licensed electronics technician for over 47 years, with relatives having worked in the electrical and national grid systems, there is some information on EMP that is exaggerated.
The electrical companies have been hardening the 69kV, 115kV and 230kV 3-phase transmission systems for decades. I don’t know about the 500kv or higher systems. The substations have been hardened for decades and that effort continues as technologies advance.
The problem is local wiring that serves as electromagnetic pickup “antennas”. The longer the unshielded wiring the greater the gain (voltage). Shielding does work. Solid shields vice mesh or braided shield are nearly perfect. Your car or truck electronics will survive. Your phone and small unconnected electronics will very more than likely be fine. Unshielded DC wiring between an A/C converter brick and an electronic device (USB, audio, HDMI, etc.) will be a problem. It’s devices plugged into your street feed if you don’t have a house-wide surge system installed at your service panel that are most susceptible. Even with that the home wiring makes a great antenna.
It will have to be a truly spectacular device(s) designed to generate an EMP to be be effective. Those will be only the nuclear big boyz that can not only generate it but also must deliver correctly.
Thanks for the facts, logic, and sanity.
The EMP threat is real, but has been tremendously exaggerated.
I have read the congressional report. I know people who supported EMP localized testing facilities.
You are correct.
