Abstract
Transformers are fundamental components of power transmission systems,with their operational sta-tus directly influencing the safety and stability of the power grid.Given the complexity of the operating envi-ronment within transformers,influenced by factors such as overloading,insulation degradation,and partial dis-charge,monitoring their operational status is particularly critical.Chromatographic analysis is a widely utilized and efficient method for fault diagnosis.By analyzing the composition and concentration variations of dissolved gases in transformer oil,potential fault types and their severity can be identified.Abnormal increases in charac-teristic gases during chromatographic monitoring frequently signal issues such as electrical discharge,overhea-ting,or insulation degradation within the transformer.This paper presents a detailed analysis of a representa-tive case concerning abnormal hydrogen content increases during transformer operation.Using comparative a-nalysis across multiple diagnostic methods,the underlying defect in the transformer component was identified.This study offers significant insights into power production.关键词
