for switching purpose we r using exciter in alternator.in case of alternator we want some current like 4600 A we can't get directly so we use exciter that exciter field winding will transfer the flux to alternator winding .so we can get that much current.

How we can determine short circuiting current any plant and for example a plant which power generation is 415 volts and plant load is 500 kw.
