| Abstract: | This paper presented one rare short-circuit fault of 500 kV main transformer and its causes.A turn-to-turn short-circuit fault on high-voltage winding was concluded from oil analysis and partial discharge results.The reasons related to the short-circuit was expounded,and some anti-accident measures were carried out. |
| Keywords: | transformer turn-to-turn short-circuit cupric sulfide |
