| Abstract: | Due to there are many different problems can cause the voltage transformer to damage in power system operation,this paper introduces a damage event that the low-voltage loop of two voltage transformers failed at the same time caused by misoperation of the isolation switch and phase-deficient operation,then analysis the reasons theoretically,and finally series of preventive measures are put forward in this paper. |
