变压器故障分析及诊断研究Transformer Fault Analysis and DiagnosisAbstractThe transformer is a very important part in the power system,and its operation issafe,stable and reliable,which will directly affect the operation of the power system.Inthe process of transformer running over a long period of time,failure is inevitable,sowe need to do transformer latent fault forecast in time,so as to guarantee the safeoperation of transformer.This paper introduces the general fault of transformer and the analysis of thecauses,as well as some commonly used diagnostic methods at present,the twofocused on DGA and HPLC methods,they are widely used now and more commondiagnostic testing tools.In addition,using MATLAB to areas outside the faultsimulation experiment was carried out,and make the corresponding analysis.Key Words:transformerfailure analysis fault diagnosis
