Corner Grounded Delta Transformer Schematic

There should be no ground. Solidly (effectively) grounded (lrg) solidly (or effectively) grounded systems connect (bond) the system neutral directly to earth ground. Voltage is essentially equal to ground. In principle one could configure (in your schematic) the delta corner opposite the center.
