Answer Posted / salah
Dyn11-secondary voltage lags primary by 30degree
Dyn1-secondary voltage leads primary by 30deg
hence it is not satisfying the condition for
pare;;alisation .
if we connect two TR in parallel current drwn form the
source by both transformer is not in phase hence
circulating current will produce & damage the winding as
well in secondary aslo
