【Abstract】 This paper, based on model experiment and numerical computation, presents the principal characteristics of ferroresonance developed by electromagnetic voltage transformer, points out the possibility and the limitations of conventional methods of restriction on overvoltage, and provides a new method of suppressing the ferroresonance by means of voltage stabilizer for the purpose of forced fixing the terminal voltage and absorbing the resonance energy. The detailed study shows that this method is quite effective.更多还原
