It turns out that the grid can be protected from solar EMP devastation by outfitting it with surge suppressors, much like the ones that protect our computers and plasma televisions at home. In a nutshell, solar EMP blasts hit the Earth and discharge massive electrical currents into the planet's surface, some of which current surges back up and into the grid. Surge suppressors placed between the surface and the transformer would protect the transformer from the space weather-induced electrical currents coming up from the ground.
No Surge protection on the US Grid transformers. This must be being reported as incorrect even to prevent cascade failure of the whole grid even during a non so called Solar Katrina event storm. Thats like installing a home electrical wiring system without any fuses (even using a conventional fuse board rather than RCD is a major safety improvement factor) and using aluminium wiring. You have a high risk of burning the house down or getting fatally electrocuted despite the economic benefits.
