The reliability of the power transformer operation is closely linked to the security of a power system and the reliability of power supply. For the sake of the improvement of transformer on-line fault diagnosis accu- racy, it is significant to put forward an algorithm based on an artificial immune system and fuzzy C-means clus- tering by using the online monitoring of transformer oil dissolved gas composition content. The particular em- phasis was paid on the introduction of data processing of transformer faults, the identification of transformer fault types on the basis of fuzzy C-means analysis, and the simulation experiment. The result of experiments shows that the algorithm can classify transformer fault types effectively, and it has a preferable application prospect in the transformer fault diagnosis.
