That the vulnerability of transformer yards to high velocity kinetic damage has been discussed in some forums for many years. The North Carolina vandalism was not the first, nor even the first this year.…Why are the media telling us about this one and none of the others? My understanding is that vandalism like this happens quite often.
20 years ago folks were discussing just this sort of vandalism and it’s effects in online forums…..It was precisely discussions like that that made me leave those forums. I was always wondering who was a Fed, and I had no interest in making the lights go out…..But some folks did. I had better things to do and more important stuff to worry about.
The vulnerabilities were discussed online, and really, no-one was able to come up with a counter…..Let the cooling oil out via a bullet hole and they stop working. Pretty much that simple. If the utilities see the overheat and shut them down early, then the damage is small, if not then the damage is much worse. Either way the lights go out.
Apparently some of the folks that talked about that sort of thing in forums have decided to act. Or their kids maybe.
Either way, the vulnerabilities have been known and talked about for at least 20 years.
