Fiber optical current sensors based on Faraday effect have a lot of advantages over conventional current sensors and have been studied extensively. To eliminate the vibration sensitivity, a light path of reflective fiber optic current sensor improved is proposed, which makes discharge of Sagnac effect with Sagnac effect itself and do not disturb Faraday Effect at all. The reliability of the system was simulated, then the polarization states for the key optical components of the lights spreading in the improved light path are analyzed with Jones matrix. The results shows that the output of the improved sensor is accordance with the actual case. A new solution for guarantee the term running of fiber-optic current transformer was provided, a feasible method for the practical use of Sagnac fiber-optic current sensor is provided.
