| Abstract: | Capacitor voltage transformer (CVT) is mainly used to measure line voltage and provide power to the secondary equipment. By analysing an abnormal heating defect of a 110KV CVT in a substation, the defect location was diagnosed through electrical test, oil chromatographic detection, and the defect causes were found out. Finally, the corresponding preventive measures were proposed. |
