why is the vector group analysis done in transformer tests

Answer Posted / dinesh kumar

1,Vector group is done on transformer High voltage winding
with respect low voltage winding.
2,To find the phase angle/difference between different
connections in high voltage windings.
3,In three phase winding transformer there are 36 vector
groups.(1u1v1w 2u2v2w)
