Hi,

The thing about an EMP device is that it is meant to be detonated
at a very high altitude, so there is no radiation poisoning
on the ground. Since the device doesn't directly cause loss
of human life, the attacked country has a quandry
whether or not to launch a "mutual assured destruction" response.

A lot of the large power plant a.c. generators would be knocked out,
because they use "brushless exciters" for the rotor.
The rotor is excited by a small separately controlled a.c. field,
and uses large semiconductor diodes
that spin along with it, to create the needed d.c. within the rotor
windings.
