| Abstract: | A method of simulating the distribution of magnetic field around the strong current by using the software COMSOL was introduced, and a reliable and practical selective basis for choosing the materials of sleeve around the strong current in the full-fiber optical current sensors was accordingly provided. Based on the Faraday's law of electromagnetic induction, the large current straight conductor model was established by the use of COMSOL software. With the help of this model, the distribution of magnetic field around the strong current was simulated respectively both in theory and in practice. The sleeve material in the fiber optic sensor distribution under different conditions of the magnetic field around the wire showing that the magnetic field is not sensitive to materials made of nickel sleeve placement. |
