Detection and Analysis Based on the Abnormal Mechanical Vibration Signal of GIS

This paper puts forward the detecting and fault diagnosis method for GIS. The mentioned method detects and diagnoses faults by detecting abnormal vibration of the GIS. The paper gives out to diagnose the different fault types of the GIS, and make fingerprints for the GIS by monitoring these apparatus. The collected vibration signal was used in the mechanical defect diagnosis, which has proved its effectiveness and precise. This method would be of significance to find out potential faults and fault positioning of GIS in early stage.
