Dyn11 and Dyn5 both are vector Group b/w phases and neutral....
D is indicate Primary side Delta connection,
y is indicate secondary side Star connection,
N is indicate Neutral and
5 and 11 is just indicate the angle
5 is show 30 degree angle and 11 is show 120 degree angle b/w star phase and in neutral connection
