A transformer acn not develop three phase power from a
single
phase source.
deu to===========
01)-single phase has only one phase syquence.
02)-a three phase transformer has three phase primary
winding it need three phase rotating magnatic field that
can not achive bu a single phase source.
03)-if we will apply single phase source at three phase
transformer,s primary winding then only one primary coil
will exited for inducting so we can achive only single
phase power output.
