Power transformer in the grid is one of the most important equipment, it can use the network of different voltage linked together, to form a complex network or large electric power system, and plays an important role in it the reliability of the power transformer is directly related to the power grid safe, efficient, economic operation. Because the transformer long-term continuous in operation of power grids, inevitably occurs a variety of failures and accidents, so how to power transformer in operation fault diagnosis, has become urgent to solve the problem of electric power sector.
IEC three ratio method is the electric power transformer fault diagnosis methods. IEC three ratio method is the IEC deliberation, in the ratio of four (Rodgers method) based on the modified and get a new simplified ratio method, it is the transformer oil cleavage to generate CH4, H2, C2H6, C2H4, C2H2 several kinds of gases are compared with each other and get a group of digital coding, according to enc
