【Abstract】 As main equipment in power system, it is urgent and difficult to analysis fault reason and repair quickly when fault is discovered in transformer. From the fact that a 220 kV transformer was damaged by short-circuit of 110 kV busbar, it primarily describes fault reason from electric experiments, relay action and fault record, and also gives repair project.更多还原
