Greg's Image above looks like a MGCN setup (Multi-Grounded Common Neutral).
The Primary -appears- to be connected as a Wye, but I am not 100% sure.
The Secondary must be Wye connected, as the Left-Side Bushing of the Two visible Pots has only a single lead with no interties; and the Right-Side Bushings have Bare Leads, which appear to be heading to the Star Point + MGCN termination.
Greg, do you have a Non-marked Up version of this Pole's Setup?
