In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
