Am I the only one who sees that the bottom 480V phase is shorted to ground in this drawing?

I believe that the wire coming out the top of CT-1 should conenct to the star-point of the transformer, not the 3rd phase.

Not everyone has a NECHB, you gotta post a picture so people can see what you are talking about.
