Yes, Freedom, but that is a worst-case and that level of preparedness is growing all the time. When the public heard about it, it was well under way. The last thing the utilities want is major outages. In building new power generating facilities, the grounding has really stepped up since I started years ago. Exponentially, I’d say
Grounding is the main component of this type of protection, as the case of a transformer is basically a shield, so better grounding shunts the EMF away.
Certain high levels of EMP will always create problems, all we can do is reduce the amount of damage. The kind of thing where artists and CGI animators use plasma energy engulfing power line illustartions would be extreme levels of energy, not much can be done there. Faraday Cage and PRAY!!!
Fortunately, the human body is fairly permeable to magnetic pulses.
