| Abstract: | Fiber optic current sensor based on giant magnetostrictive effect is the focus of current research, this paper on the basis of theoretical analysis build a system based on Fiber Bragg grating (FBG) and giant magnetostrictive material (GMM) current sensor system for sensing head, a comparison between the experimental results and the theoretical analysis results are obtained, possible the cause of error. Finally, according to the defects and shortcomings of the system and puts forward some problems needing attention, and make certain assumptions. |
