Since Distribution, LT requires neutral, hence star winding.
As already one winding is star, the other one i.e, HT will be in delta(to provide path for 3 rd harmonics). Now 11 is the standard phase angle for vectors for easy connection. 

Answer / ankit

firstly we want a neutral point at the load side because using one live wire and neutral we can form one phase.
secondly using delta star connections third harmonics is reduced
