Why is one leg of a primary winding grounded?

newbie here! We are designing a storage system with a 3-phase inverter, to be connected to the grid via a trafo. I just got the schematics from the utility company, and they said that one of the phases of the trafo is grounded on the primary side, because of stability issues (not sure I fully understand that). Could someone explain to me what that implies in terms of connecting the inverter (or point me to some reference)?


Thank you for your time!
