Answer Posted / alok
In India according to indian standard we use + or - 30 degree phase shift between LV and HV side.
so we can use Dyn11(for star LV is leading delta HV with 30°) or Dyn01(for delta HV is leading star LV with 30°)
It depend on 12 hour clock like 1=30°,2=60°......11=330°or(-30°),12=0°
