Three Letters Re: The Simple Reality of EMP — Different Than You Might Expect
Dear JWR, I read the EMP article by Andru and thought it very well done with one minor correction in the power generation area (worked in the nuclear power industry for 20 years before changing careers). The EMP E3 pulse is very dangerous to the transformers in the transmission and distribution system, and hydro-electric and nuclear will also be severely affected. Commercial generators of any output run at 8,000-10,000 volts which is fed immediately to step up transformers to feed the transmission system. The most common voltage for the transmission system is 250,000 to 500,000 volts (3 phase) which reduces …
