Abstract
The disolved gas analysis of insulating oil in the title transformer has been carried out. Combined with electrical test
the problem of internal partial short-circuit fault due to poor contact of on-load tap changer occurred in main transformer No.2 at Liyan Power Plant was discovered. Retrofitting treament has timely been carried out
occurance of a serous accident of the equipment having been avoided.
