| Abstract: | The paper briefly introduced the course of discovering hidden trouble in phase A accident of CVT during the acceptance of measurement point on certain 500 kV line. The reason for hidden trouble and accident, CVT error and its harm were analyzed in detail from the structure of capacitive voltage transformer, in which the problem in manufacturing technology of products was one of major reason for the accident. |
