A Drill To Replace Crucial Transformers
From NY Times
The electric grid, which keeps beer cold, houses warm, and city traffic from turning to chaos, depends on about 2,100 high-voltage transformers spread throughout the country.
But engineers in the electric business and officials with the Department of Homeland Security have long been concerned that transformers are vulnerable to disruptions from extreme weather like hurricanes, as well as terrorist and computer attacks and even electrical disturbances from geomagnetic, or so-called solar, storms. One such storm, in 1989, blacked out the entire province of Quebec, and this week, a transformer fire of unknown origin blacked out parts of Boston.
