摘要：

Optical current sensor is received much attention by its good performance on safety and anti-interference. It displaces the traditional electromagnetic current transformer in power grid. However the optical current sensor is limited by its shortcoming in stability and reliability. It is result in big linear birefringence and low sensitivity. In this paper a new structure of optical current sensor is designed to achieve higher sensitivity about 580 times than traditional structure. The system transmission field has been obtained by simulating the transmittance of light propagating through optical sensing head by COMSOL software. The result obtained from the present work is useful for further research on the optical fiber current sensor.
