why is the vector group analysis done in transformer tests
Answer Posted / saba anjum
vector group are made to know at what position the secondary
winding of transformer we get star and delta voltages . and
it indicates the type of winding in primary and secondary
which helps in parallel operation of transformer with
different ratings having same vector group .
