| Abstract: | The paper analyzed the unusual phenomenon of oil color spectrum caused by discharge of iron yoke tape in a large power transformer. The fault point of the power transformer was accurately diagnosed,and the transformer was inspected and handled disassembly on site. The improvement suggestions for avoiding this kind of fault were put forward. |
