20140212100 | STRESS CONTROL STRUCTURE FOR OPTICAL FIBERS IN A HIGH VOLTAGE ENVIRONMENT - Structure is provided for controlling the electrical stress on one or more optical fibers in a high voltage environment. | 07-31-2014 |
20140300341 | ELECTRO-OPTIC CURRENT SENSOR WITH HIGH DYNAMIC RANGE AND ACCURACY - An optical sensor that senses current by directing polarized light across an airgap that is orthogonal to a direction of current running through a conductor. The sensor includes a prism having a high Verdet constant for high sensitivity to magnetic fields, which cause an angle of polarization of the polarized light to be rotated as an indication of the magnitude of current. A polarizing beamsplitter having a low Verdet constant is mounted to the prism so that incoming light that is traveling in a direction orthogonal to the magnetic field being sensed across the airgap is insensitive to unwanted magnetic fields produced by nearby conductors. The distance the light travels in this orthogonal direction is minimized, reducing the overall volume of the sensor, making a compact sensor highly sensitive to magnetic fields of interest, largely insensitive to unwanted magnetic fields, and having a very high dynamic range for sensing current. | 10-09-2014 |
20140340806 | STRESS CONTROL ASSEMBLY AND METHODS OF MAKING THE SAME - A stress control apparatus for managing effects caused by electrical stress in a high voltage environment, and methods of manufacturing the apparatus. A dielectric tube with a central bore coated with a conductive material has an outer conductive coating on a lower section that is grounded. The central bore carries a high voltage potential from a current-carrying conductor. The grounded coating transitions to the exposed outer dielectric surface along a gradually tapered transition. A conductive insert connects to the central bore and forms an electric field in a space between the insert and the grounded coating. When coated with an epoxy and inserted into the central bore, the insert forms a small gap between an outer surface of the insert and part of the central bore, such that there is no zero potential difference in the gap. Any epoxy that oozes out during insertion will collect in the gap. | 11-20-2014 |
20150023629 | COLLIMATOR HOLDER FOR ELECTRO-OPTICAL SENSOR - A collimator holder in the form of a glass or ceramic block that has precisely machined holes formed in the block to receive respective collimator assemblies. Each collimator assembly includes an optical fiber attached to a GRIN lens by a ferrule. Optionally, each collimator assembly can include a glass tube that surrounds at least the lens and optionally part or all of the ferrule. The lens or the tube is inserted into the hole and bonded therein by an epoxy. The block, together with the collimator assemblies installed, is bonded to the bottom surface of a crystal assembly thereby forming an electro-optic sensor. The crystal assembly can include one or more polarizing beam splitters, an electro-optic crystal, and a prism, configured to sense a current through a current-carrying cable or a voltage between the cable and another potential. | 01-22-2015 |
