In view of complex structure,diversified fault types,and multiple states of transformers,this paper establishes a transformer fault diagnosis and state evaluation model based on multisource information. The state evaluation is carried out step by step according to the hierarchy of fault index evaluation,component state evaluation,and equipment state e-valuation,providing an effective judgment method for comprehensive diagnosis of transformers. Moreover,for transform-er fault diagnosis,this paper proposes a multi-dimensional fault diagnosis method that quantifies the severity of transform-er faults through fault indices,providing a scientific and rational evaluation method for their relative deterioration and fault severity.
