Hopefully someone can be there Friday to take pictures. I want to see what a 12kV transformer looks like before it is covered up!
The transformer will be quite large (over 5,000 pounds with 200 gallons of oil inside)...Typically there are work clearances required, so you generally don't see them covered. Here is a photo example (on the left) of a transformer installed at an eVgo site that is good for about half of the power that an SC site draws...
