Answer Posted / qasim ali
there are two types of exitation:
rotary
static
rotary:in it , dc generator is used for excitition, that have the combination of sliprings n carbon brushed,this generator has a moving rotor n static stator..sliprings converts the axial motion of current to radial,and then dc frm this generator is given to poles of ac generator..
static:
here ac supply is taken from reserve power distribution center(rpdc) i.e frm 11kv or smthng else trnsmissin lines n then it is stepdown 400v by excitation trnsfrmr n then this ac passes through rectifier bridge .and then it goes to poles of ac genrator....
