(OP)
we have delta star transformer with star point grounded.

my question is:
in case of earth on star side will relay on delta side see the fault? if not,what happens with the currents on the delta side during the earth fault?

RE: delta star tranformer

The delta side will see heavy current but the relay will not know that it is the result of an earth fault.
