With the applications of GIS to the field of high voltage and UHV,GIS has the trend of miniaturization,modularization and intelligence,which put foreword new requirements to the TA for GIS.The emergence of electronic current transformer provides a new structure mode of current transformer application technology for GIS.Different manufactures have different structures of GIS.TA's structure for GIS is also different.The common structure of traditional electromagnetic type and electronic type TA and its applications are introduced in this paper.By the comparison between the different structures of TA for GIS,the reference of the structure design of TA for GIS is offered.
