Power transformer fault diagnosis using fuzzy logic technique based on dissolved gas analysis and furan analysis

摘要

This paper presents a diagnostic system which implements several most widely used methods, using fuzzy logic, for fault diagnosis in power transformers using the dissolved gas analysis and furan derivatives analysis. A case study carried out for a power transformer is presented for the validation of the diagnosis system. The results obtained led to the rehabilitation of the transformer and putting it into service within normal parameters. Our system is open that mean it can to exchange data (data input and results) in wide range of data formats like Excel files, MySQL database and OPC client/server technology.
