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.

Optical sensor system having a segmented magnetic flux concentrator and methods of use thereof

An optical sensor assembly that senses current in a secondary electrical cable while sensing voltage in a primary electrical cable. The optical sensor assembly may include a sensor body, a concentrator core for measuring current. The concentrator core may be attached to a first end of the sensor body. The optical sensor assembly may include a plurality of extension arms that extend from the sensor body. The extension arms may include clamping devices on one end that are configured to attach to a first electrical cable. The concentrator core may be configured to at least partially surround a second electrical cable and sense the current from that second electrical cable.
