ABSTRACT:
An optical sensor assembly has a base unit, an optical current sensor, and a magnetic concentrator. The optical current sensor is mounted on the base unit and includes a polarized light input, a reflective prism, and a light output. The magnetic concentrator defines an airgap and is mounted on a concentrator housing such that the magnetic concentrator fits around the current carrying cable when the base unit is hung from the current carrying cable by hooks and when the concentrator housing is moved to a closed position. The reflective prism of the base unit is operably positioned in the airgap of the magnetic concentrator when the concentrator housing is in the closed position. The assembly further includes a voltage sensor operably positioned in the base unit for measuring the voltage of the current carrying cable.
