Application Of The Power Transformer Winding Deformation Diagnosis Method

In recent years, there are many accidents about power network because of thetransformer winding deformation at home and abroad. It is a great damage and has a badeffect for the local economy and society. So the commissioning test and regular checkup arevery important to prevent the accidents from happening. In this article the main content is thesynthetic analysis of testing methods about winding deformation, and combing with workexperience so that we can have an in-depth study of the testing methods, then the researchresults can be applied to the actual test. There are six chapters in the paper.The article shows that why the transformer have a winding deformation and the harm ofit.Through the analysis of equivalent circuit of the transformer winding,the influence of thewinding deformation to the equivalent circuit,the use of the correlation coefficient,it makes anindepth study of the frequency response method and the frequency response curbe.Ingeneral,the article is thesis is correct andi the arguments are sufficient, The write bases on thereal work of himself,expalaind why the frequency response curve appears translation,messypoints,unstable condition and sunmmarizes the solutions.
