Abstract: A voltage sensor comprises a conductor (102) having a first end (101) and a second end (103), the first end including a first connection interface (150) and the second end having no connection, and a sensor section (125) including at least one sensor disposed over the conductor, the sensor sensing the sensor sensing at least a voltage or a sample of the voltage of the conductor. The voltage sensor is coupleable to a power line or cable, such as an overhead power line or cable, or a cable accessory, and can also be used in underground applications.

Abstract: A sensor for a separable connector includes a plug body, one or more high voltage capacitors, one or more low voltage capacitors, and a low voltage connection. The plug body includes an insulating resin. The plug body can be inserted into the separable connector to encase a high voltage conductor disposed in the separable connector. The one or more high voltage capacitors are encased by the insulating resin and can be electrically coupled to the separable connector at a first end portion when the plug body is inserted. The one or more low voltage capacitors are electrically coupled in series to the one or more high voltage capacitors to form a capacitive voltage divider. The low voltage connection provides a low voltage signal corresponding to a high voltage signal present in the separable connector. Signal conditioning electronics or a memory may also be included.

Abstract: A terminal connection device comprises a contiguous body disposed onto an inner conductor. The inner conductor includes a first end mateable with a power cable connector and a second end. The body comprises a multilayer structure having an inner conductive or semiconductive layer disposed over at least a portion of the power cable connector, an insulating layer and an outer conductive or semiconductive layer. The body surrounds the first end of the inner conductor and extending towards the second end of the inner conductor. The body can also include an electrically isolated section of conductive or semiconductive material. The terminal connection device can be a fully integrated structure, having a pre-installed connection interface, or the terminal connection device can be configured as an adapter which can be mounted in the field to a connection interface.

Abstract: A sensor for a separable connector includes an elongate plug body extending along an axis and includes an insulating resin. The plug body includes a high voltage connection at least partially encased by the insulating resin and includes a low voltage connection spaced along the axis from the high voltage connection. The plug body also includes a substrate at least partially encased in the insulating resin and extending around the axis between a high voltage portion and a low voltage portion of the substrate. A circuit is disposed on the substrate and extends from the high voltage portion to the low voltage portion of the substrate. The circuit includes a plurality of first impedance elements electrically coupled between the high and low voltage connections. One or more second impedance elements are electrically coupled to the circuit via the low voltage connection to form a voltage divider.
