Transformer fault diagnosis based on relative losses of negative sequence power

Guo Taisheng~1 Zhou Ling Ding Xiaoqun~2 (1.Suzhou Water Company,Suzhou,215002) (2.College of Electric Engineering,Hehai University,Nanjing,210098)  
With the own losses of negative sequence power of transformers,this paper introduces a new characteristics of transformer fault diagnosis based on the relative ratio losses of the negative sequence power.Through theoretical study,it is demonstrated that the application of this method to transformer fault diagnosis is reasonable and feasible through examples.
