TO operate transformers in parallel, vector symbol of the
both should be same.If one transformer name plate is not
there, how can we conclude that whether the transformer is
having the same vector symbol or not?

Answer Posted / guru

Check the vector group by carrying out VECTOR Group testing
( By Injecting a 3 Ph 440v or 230 V to the primary windings
and check the voltage between the terminals in secondary
side)

For each vector group there are standard values which has
to come in the secondary side
