Looking at the Jan 5 additions to this page, a lot more work needs to be done. The concept is that a transformer uses magnetism to recreate an AC current in a separate circuit at a different voltage. Transformers can be damaged by certain conditions. Some people advocate placing transformers in a Faraday cage to protect them from such conditions. This could apply to high voltage transformers as well as the medium voltage transformer serving an apartment building or city block of houses. Admittedly, if a high voltage transformer goes out serving an entire town, it would be more disruptive than losing a medium voltage transformer that serves just one apartment building. However, for everyone to continue to get electricity during a solar event or a terrorist attack, all of the transformers between the power station and the user would need to remain operational. Creating resilience from a smart grid will include a lot more than building Faraday cages.

So this article places undue weight on just one piece of the problem. A grid, which is controlled by computers, could isolate or turn off the flow to transformers through a remote cyber attack without working to attain the proximity needed for an impulse attack.

More generally, the article could have been expanded to explain some of the physics behind the idea of a transformer. The relationship between voltage and current. The article could explain why we use transformers to step up voltage (to reduce Jewel heating line losses) on long distance transmission. The link between transformers and AC current should be explained.

There are also style problems with a two paragraph quote that is left unclear where the quote begins and ends -- did you leave out at least one quote mark? In general, CP frowns upon two-paragraph-long quotes. We usually like to try to put things in our own words.

If a concept is hyperlinked in the text of the article, there is no need to include it in the See Also section. Thanks for your efforts. Wschact 02:16, 5 January 2015 (EST)
