Abstract：Voltage transformer is an important power equipment used to monitor system voltage .Voltage transformer is mainly divided into electromagnetic and capacitor voltage transformer. Capacitor is most widely used at present, especially in the 110kV power system and above. Simply introduce the structure and principle of capacitor voltage transformer. Analyze and study on the abnormal secondary voltage of a 110kV capacitive voltage transformer, and find out the reason of the anomaly. Then put forward some corresponding measures which can provide some reference value for analyzing the accident of other power equipment.
