delta delta banks
(OP)
I just recently started on a new system which is completely 12470 y primary. Today a lineman told me that the system has a few delta/ delta banks. I have never heard of anyone having a delta/ delta bank on a 12470 y primary. Is this possible?

There would be 12,470 V between each of the bushings and across the winding, not 7200V.

We STILL have a few old Delta-delta services (and even one open-delta) that have lingered.
(Until a customer makes a change to his main service, there is no way to enforce an upgrade, and these legacy customers are unwilling to spend a dime to 'modernize')
