| Abstract: | In the paper, the nooperation behavior of unbalance voltage protection after C phase wire breakoff fault on 10 kV capacitor in a 110 kV substation is analyzed. And the existing problems of unbalance voltage protection in the single star connection way of capacitor are discussed. Furthermore, in order to prevent such similar problems, it is suggested to add the current criterion. |
