| Abstract: | Through the analysis of distinguishing coefficient in the analysis of degree of grey incidence, the properties ofdistinguishing coefficient and the rule of its assignment areobtained, and on this basis the concept of degree of areaincidence is put forward. By the analysis of practical example, it is proved that the attributes of insulation fault can beeffectively diagnosed by the degree of area incidence and it can be also used in the fault location of transformer. |
