| Abstract: | A low reactance at the neutral point of transformer is considered to be an effective method to repress single phase short current. In this paper, the effect of the neutral grounded by the low reactance on switching over-voltage in the power system is studied. Through deduction and analysis, the conclusion can be made: low reactance at the neutral point of transformer has little effect on the switching over-voltage in power systems. |
