| Abstract: | Using the current transformers designed by the dual fiber Bragg grating (FBG), the temperature compensation based on the square giant magnetostrictive materials and the current transformer of FBG is realized, the center wavelength drift compensation in FBG caused by and the heat expansion of the square giant magnetostrictive materials is also realized. The measurement accuracy of this optical current transformer is increased. |
