New Application of Fibre Optical Current Transformer in Smart Retrofit Substation

Abstract:

The paper studied the outside attachment of fibre optical current transformer in smart GIS substation innovation projects. Based on Ampere circuital theorem, sensing optical fibre can be wrapped around the flange at the bottom of the GIS bushing without modification damage on GIS components and long time power cut. The experiment result proved the accuracy and feasibility of this new application. Furthermore, kinds of electronic transformers are compared with fibre optical current transformer, and the analysis gives a conclusion that fibre optical current transformer could be the optimization of system design in smart substation innovation projects.
