Can anyone explain how the vector diagram of a transformer
which doesn't have name plate be found whether it is
Dy11/Dy5/Yd11 and so on?

Answer Posted / loke

Ya ! first of all you can decide Yd or Dy by seeing it
primary & secondary connections and 1,2,3....11 we can
decide it by doing vector group tests int that we can check
phase shift of wave form & we can conclude
