Answer / muthuvel

No,If you connect Bus coupler between the secondary sides of
transformer.. Trans will get parallel operation.This will not
be possible we cannot able to make parallel
operation,synchronise the transformer to make that all the
elec characteristics should be equal for the transformers.

Answer / rajeshkumar k

no,if we want to connect the secondary side we need synchronization we have to match the v,phase sequence,f.if we use bc it wouldn't couple because efficency of transformer of same rating will differ, it should need synchronization.
