What is the open circuit voltage?

at secondary side of 11 kv/433 volt 25 kva delta/star with neutral transformner, supplied 11 kv side with one phase line is open circuited (i.e. only two phase is connected at 11 kv side with 11 kv voltage.

With one primary line open, the phase between the remaining 2 have the 11kv. The other 2 phases have that 11kv across them, so 5.5kv each. The one secondary phase will have 433V and the other will have 216.5V (the phase angles are messed up too of course).
