Abstract
The fault of internal arc discharge of the 110 kV transformer was discovered and confirmed in time by using oil chromatographic analysis and three-ratio method, avoiding major equipment accidents. Reliable measures were drawn up to ensure safe and reliable op-eration and start-stop of the generating unit without high-voltage standby power source.关键词
