Abstract

Aiming at the low monitoring value of electromagnetic field strength in the form of single-wire wound magneto-optical medium commonly used in traditional optical current sensors, an optical current sensing structure combining magnetic material ferrite and magneto-optical medium is designed. The simulation analysis of COMSOL shows that the designed sensing structure can mon-itor and measure the magnetic field through optical sensing, and then achieve the purpose of measuring current. Compared with the traditional structure, the measured magnetic field strength value is increased by 3.05 times. The optimum radius and optimum axial intercept of the coil are obtained.
