This paper analyzes the rotor magnetic potential distribution of one large turbo generator both in normal and rotor inner winding short-circuit fault states. By the influence of short fault, the second harmonic current of the stator winding will induce one half and one two-third harmonic currents to the stator winding and the rotor winding respectively. Furthermore, it also analyzes theoretically the effect of inter-turn short circuit on characteristic parameters, which include the stator current, the stator voltage, the rotor current, the rotor voltage, and the active/reactive power. Then a method is proposed to predict or identify different practical faults in details, which is on the base of the relative variation laws of those character...
