Seems like this EMP moves a lot faster than ordinary power surges like from lightning. Not faster in terms of speed, just that the impact hits and peaks faster, three or four times that of a lightning bolt hitting your electric line. So fast that the relay inside the surge protector doesn't have time to trigger off and, boom, the whole system is fried. That's why it's so darn dangerous. It fries out all electronics before any of the built-in protections can react."
