if dc excitation is used to produce manetic flux in rotating
machines then ehy it is not used in transformers.
Answer Posted / subash
To generate the voltage in generator extitation voltatge is
required to create magnitic flux ,
but in transformer the winding is connected to supply mains
the winding itself produces flux
