Default An Attack On Our Power Grid? Keep Your Onan On Standby

I read an article this morning which I linked below. It appears the little fat man in North Korea is threating to take down our power grid with an electromagnetic pulse (EMP) onslaught, a threat that experts contend is both very real and comes with catastrophic consequences. I am not a nuclear scientist, but how will it affect our generators.

thanks for the heads up JC. I am making some tin foil hats for all of my gensets asap. I am no expert, but it seems if they could take down the grid it may affect some of the newer more fancy generators , but probably not the old school stuff.

This has been studied for years. Pop a nuke high in the atmosphere and the grid for x hundred or thousand miles goes poof. One project I worked on with the pHd guy I worked for was for mission critical equipment EMP mitigation. We had meetings in DC with a lot of gingerbread military types and a few senators which ultimately netted the big zero. Everyone other than military has their head in the sand.

Bottom line is that the old non electronic controlled equipment and older diesels will be fine. But with the grid down you won't be able to get fuel so you're borked regardless.

There will be fuel out there you just have to take it at the same time your getting all the canned goods from the guy down the street you just shot IF he don't do you first. And keep a few spare points and condensers and coils for your model genny.

Will this mean that the electronic voltage regulators such as the type installed in the J series would be affected?

All the electronic bits we got from the military came in foil pouches for emp protection. Strong emp can destroy old school stuff but it is more resistant. For maximum protection store your generator in a sealed metal box. Wrapping in tin foil actually will help also.

I think this is why old Soviet MiG fighters had vacuum tubes

FoxNews just winding up the old people, again Contrary to popular opinion, countries don't develop nukes in order to actually use them

the possibly of an EMP attack is very real, if you look at the photos of the fitzgerald after being rammed by the cargo ship it ia clear to me that the ship was dead in the water and that the communications on the ship were knocked out that could explain the delay in calling for help...

Little Jim is crazy enough he might actually do it though. It would mean the swift and complete annihilation of his country, but he's arrogant enough to try it anyway knowing how many of our soldiers will die trying to smoke him out of his hole.

The scary part is he wouldn't have to even hit US soil in order to trigger an EMP of sufficient magnitude to paralyze the US, especially because said EMP could strike areas that are already damaged by wildfires and hurricanes.

I was a nuclear weapons affect engineer for a good portion of my career. I was involved in critiquing EMP hardness proposals for a military communication system. I have to chuckle about stories like EMP is going to fry our power grid. In a way that may be true especially if the "electronics" do not employ conducted EMP transient protection on all interface circuits. As for the HV power lines they employ 20 cycle reclosing lightning protection which may or may not react to the much higher and powerful EMP only if there is flashover generated power flow across, for example, a HV insulator. This can happen as an EMP event upsets the earths magnetic lines of force as they swish back and forth. Sun spots can also do something similar.

The EMP problem is that the frequencies generated are much higher, more powerful and more wide spread than lightning and that makes any un protected interface circuit vulnerable if and only if enough energy gets conducted to let's say to a system controlling computer.

Another reason I like the Magneciter because there is NO electronics in the design and what little EMP couples down through a conducted transient will,be of no consequence. BUT and a big but, the utility computers which control the natural gas supply to my JB may be vulnerable if not EMP hardened, and I'll bet they are not. Of course the amount of EMP that would get to any particular electronic system depends in great part on the topology of the wiring which determines the amount of coupling thus damaging transient pickup.
