Research on Monitoring and Fault Diagnosis of Main Ttransformer Inrush Current in Substation
The article mainly studies two aspects of monitoring and fault diagnosis methods for the main transformer current in substations.In terms of main transformer current monitoring methods,four methods are mentioned such as traditional current transformer,current sensor,fiber optic current sensor and intelligent sensor monitoring technology.In terms of main transformer current fault diagnosis,four diagnostic methods are introduced in detail,including insulation type test,spectrum analysis,thermal image camera and gas analysis.Each of these methods has its own characteristics,and according to different types of faults and situations,suitable diagnostic methods can be selected for fault identification,localization and analysis,providing an important basis for timely and effective troubleshooting.
