| Abstract: | A 220 kV capacitor voltage transformer accident is analyzed,the cause of which is found by on-site inspection and returned disintegration. Capacitor voltage transformer internal high energy discharge caused by the production process failure. Further damage is prevented. The experience for the safe operation and technical supervision of the 220 kV capacitor voltage transformer is accumulated. |
