Answer / nibel

the vector group of the transformer wil be seen in the name
plate. for example if its dyn11 means delta star with
neutral.11 means 11 o clock is the phase angle between
voltage and current(30 deg lead)

Answer / arun

we can check the transformer vector group and polarity of
tansformer.ex.Dyn11 in name plate .11 "o" position we are
check th tansfomer
