Development And Application Of Transformer Fault Diagnosis System Based On Dissolved Gas Analysis

Dissolved Gas Analysis (DGA) is a very effective method to predict and diagnose transformer faults.In this paper, diagnosis method based on DGA is analyzed.IEC standard, fuzzy theory and expert system are integrated to diagnose the transformer faults.C++Builder and Access are employed as development tools to develop a transformer fault diagnosis system based on DGA for Shi jiazhuang Power Corporation.The system is short in codes and easy to maintain, amend and extend.This method is very meaningful and applicable.Zhao Ligang (Power System and Its Automation) Directed by Prof.Lu Fangchen...
