Orthogonal Conjugate Reflecting Current Sensor

摘要

A new design of optical current sensor using a Faraday Mirror directly as the current sensing element is proposed, the optical setup is shown, the mathematical expression of the working principle is derived, the experimental result is given, the advantages and shortcomings of the design are discussed in this paper. This design may be used as the primary current sensing element of an electrical current transformer for high voltages applications.
