摘要：In order to effectively detect the mechanical condition of Gas Insulated Switchgear (GIS), Empirical Mode Transform (EMD) is proposed to analyze the vibration signal, then Intrinsic Mode Function is obtained. Feature matrix and similarity matrix are defined based on the power spectral density function and vector space model, forming the criterion of GIS mechanical failure. Two common GIS failure like screws loosening and particle vibration are built, 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. © 2016 IEEE.
