Study on Transformer Fault Diagnosis Based on Dynamic Fault Tree

In this paper, according to theoretical diagnosis of fault tree, the author builds a diagnosis model based on dynamic fault tree and illustrates the model’s construction method and diagnosis logic in detail. According to case analysis, compared with conventional fault tree diagnosis, the above-mentioned method is advanced in fault-tolerant ability. Plus, the diagnosis results record some intermediate processes of the diagnosis, with relevant information being returned to the researchers as ideas facilitating further analysis in the event of incomplete information.
