the first letter must be capital one, which represents HV
winding while second letter should be lower case, which
represent LV winding of transformer.
1. 'D' - HV winding is delta connected & 'Y'- HV winding
is star connected
2. 'd' - LV winding is delta connected & 'y'- LV winding
is star connected
And rest of number indicating phase displacement angle
i.e 1 = 30°, 2 = 60°, 3 = 90°, 6 = 180° and 12 = 0° or
360°.
so
Dyn11 indicates,
Delta connected HV winding, star connected LV winding with
neutral brought out, LV is leading HV with 30°
