Hi Christopher. This may give you some idea as to what you are up against when it comes to EMP. The following is from an nuclear explosion, but EMP no matter the soruce has the same effect. It depends upon the strength of the EMP. Take Care…Don in creepy town.
ELECTROMAGNETIC PULSE = EMP
What will it mean for you? EVERY Nuclear explosion creates EMP, on the surface of the earth OR a high altitude burst. Every bomb makes EMP.
So that means you can’t hide from it. It will NOT hurt the human body, but the effects will cause great hardship for millions. EMP creates 50,000 volts of charge PER meter. About the same as a yard. That charge will "FRY" all the computer chips in things not protected. The largest radio stations at 50,000 watts, only produce about 10 volts per meter. Cars with ignition chips won’t run. Your PC System will be damaged, "unless" you do the things to protect it. I will explain how in a minute. The entire power grid in the USA will be damaged from a very high Nuclear Bomb somewhere over the central USA. A very high bomb (about 200 miles high) its sole purpose is to wipe out the power grid and communications coast to coast. Radios, TV, computers, any thing built in the past couple of decades will probably not work. There will be some exceptions. When atom bomb tests were done in the South Pacific during the 1950’s the EMP damaged stuff in Hawaii about 800 miles away. And those were low surface bursts.
Most of the EMP energy lies in the "radio frequency spectrum" ranging from power lines to radar systems, AND everything in between, which means all kinds of computer chips.
EMP happens to fast for a lightening pole or rod arrestors, to protect the equipment. Though it is faster than lightening, it does the same kind of damage to electrical grids, small OR large. It just melts the circuit.
Typical collectors of EMP are long wire runs. Antennas, telephone lines, power lines, barbed wire fences, sprinkler lines, metal buildings, buried metal pipes, railroad tracks, great amounts of metal objects. Even the mass of electrical wiring in your own home will collect the EMP. The metal pipes in your home plumbing for water will collect EMP. In some rare cases just unplugging a radio or TV "MAY" be enough to protect it. Your equipment can be protected, buts it’s not practical. You can’t protect it and use it at the same time. Hope this is of some help. Take Care…Don in creepy town.
