An optical sensor assembly, for installation on a current carrying cable, senses the current in the cable and provides an electrical output indicating the current. To sense the current, a magnetic concentrator is placed in close proximity to the cable and creates a magnetic field representing current in the cable. An optical current sensor, within the created magnetic field, exposes a beam of polarized light to the magnetic field. The beam of polarized light is rotated thereby, by Faraday effect, according to the current in the cable. The amount of rotation is analyzed and converted to electrical signals to portray the current in the cable. The electrical signals may be processed, evaluated and analyzed to provide one or more of several elements of quality of the current in the cable.

Optical sensor assembly for installation on a current carrying cable

A method of measuring a current of a current carrying cable teaches the first step of providing an optical sensor assembly comprising a base unit, and an optical current sensor mounted on the base unit for transmitting a beam of polarized electromagnetic radiation to an optical fiber. A light detector is also provided having a first channel that operably connecting the light detector to an analog to digital converter through a programmable gain amplifier, a second channel that operably connects the light detector directly to the analog to digital converter, and a processor operably connected to the analog to digital converter. The optical sensor assembly is mounted adjacent the current carrying cable, and the fiber optic is operably connected to a light detector. A plurality of factors are then evaluated from rotation information from the light detector, by using the first and second channels for analog to digital conversion operably connected with the processor.

Method for measuring current in an electric power distribution system

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.

A probe apparatus disclosed for use in a separable connector includes an insulating body and spaced apart first and second electrical conductors in contact with the insulating body. The first and second electrical conductors have adjacent surfaces configured such that when an electrical potential is applied between the conductors, an electric field is formed between the conductors. The insulating body has an opening positioned between the conductors and adapted to receive a sensor such that a portion of the sensor is subjected to the electric field. A separable electrical connector system is described including the probe apparatus, as is a voltage sensing system including the probe apparatus and a voltage sensor positioned within the opening of the insulating body.
