Development of a fiber optic current sensor for power systems

A description is presented of an all-fiber optic current sensor. A method for producing highly stable sensing coils and techniques for interfacing these coils with novel polarizing fiber are described. The performance of a fully functional prototype device is discussed. Theoretical limits and prelim...
