| Abstract: | The causes and malfunction of a 35 kV 2# main transformer are introduced. Combined with protection action report and fault recorder chart, the reasons of high voltage side protection action and low voltage side protection do not action are analyzed. The suggestion of fixed value is proposed to ensure the safety operation of the device. |
