Recent advances in optic current sensors
Electric current may be measured optically by utilising the Faraday megnetic-optic effect. Devices using optic fibre or optical bulk glass as their sensing elements have been intensively researched and developed. This paper outlines the main problems associated with Fibre optic current sensors and reviews recent development in the optic bulk glass current sensors based upon the Faraday effect.
