Research on orthoconjugate reflector current sensor

To solve the problems induced by the influences of the reflection-induced retardance and linear birefringence existing inside the glass current sensing elements to optical current transformers,a design of the optical current sensor is proposed using a Faraday mirror as the primary current sensing element.The paper showed optical setup,established the mathematical model,derived the working principle,given the experimental result,and discussed the advantages and shortcomings of the design.The results show that the design is rational and experimentally verifiable.After development,this design might be one practically applicable optical current transformer design.
