The Study On Dissolved Gases Analysis Technology Of Power Transformer

Power transformer plays a decisive role in the transmission and distribution of power system. Extensive attention has been pained on the power transformer fault diagnose.And the dissolved gas is of the most important in transformer fault diagnosis.So,the analysis of dissolved gas is necessary.This paper has researched on the Dissolved Gases Analysis.Collected data to build a DGA sample set of faults.A transformer oil dissolved gas level diagnosis model had been set up.Got an effective diagnostic results by choosing an appropriate classifier.Artificial neural network is used for dissolved gas in transformer oil diagnosis.And a fault diagnosis expert system had been built.In this paper,The diagnosis result have guiding significance for the maintenance.The proof of a great deal instance indicated the validity and reliability of this expert system towards transformer diagnosis and analysis.
