National Grid Training Facility: Regulator

On the pole in the center of the pic there's a transformer at the top of the pole and a regulator toward the bottom (though normally would be mounted toward the top of the pole; it's low down for demonstration purposes and none of it is live). The regulator regulates the voltage based on peak times and stuff. It had some cooling fins that you can barely see toward the right hand side of it. I joked that it looked like a giant coffee mug.

Also, kinda hard to see in the pic, but the top shelf of that rack just to the right of the opened bay door (look to the left of the utility pole the regulator is on) there's a big cardboard box. It's marked GENERAL (GE) ELECTRIC. Anyone wanna guess what that is? ;-)

We haven't even gotten the tour of the exterior of the facility (which parts of are indeed live; there's several street lights outside and for some reason they're all intentional dayburners, perhaps to signal that the poles are live).
