AN OPTICAL SENSOR SYSTEM HAVING A SEGMENTED MAGNETIC FLUX CONCENTRATOR AND METHODS OF USE THEREOF

The present technology relates to a current sensing device utilizing a magnetic flux concentrator loop composed of segmented ferromagnetic components. The concentrator loop is designed to focus magnetic flux generated by a current carrying cable, wire, or conductor along the Faraday rotation axis of a magneto-optic sub-assembly. The segmented magnetic flux concentrator encompassing the current carrying cable is held close to a circumferential geometry about the cable, in order to maximize magnetic flux concentration on the magneto-optic sensor. The segmented design of the magnetic flux concentrator loop, combined with a clamping mechanism, allows for easy, straightforward attachment and detachment, during installation and removal or the current sensing device from the current carrying cable.
