what does the transformer connection symbol YNaod1 mean ?

Answer Posted / sujeet pandey

you all people must be knowing about the symbols like YN and
d1 but what about a0. The 'a' represents that is
auto-transformer and 0 represents that there is 0 phase
difference b/w H.V. and I.V.(intermediate voltage) winding
since both are star-star. d1 means the transformer has a
tertiary winding which is delta connected and this delta is
lagging the H.V. winding by 30 degree.
There is no symbol for Intermediate voltage becoz all EHV
transformers are star-star connected.
