(OP)
The broken delta connection of the secondary of the VT should be grounded or not while connecting to the damping resistor. Some manufacturer catalog shows grounding connection and some not.

No, each winding set needs its own reference to ground. The reason is that capacitive coupling can cause an entire winding's potential to rise. Have a ground reference on 1 secondary winding will not directly limit the other winding's ability to rise in potential.
