Abstract: A sensor for a separable connector comprises a plug body comprising an insulating resin, the plug body configured to be inserted into the separable connector to encase a high voltage conductor disposed in the separable connector. The sensor also includes one or more high voltage capacitors encased by the insulating resin and configured to be electrically coupled to the separable connector at a first end portion when the plug body is inserted and one or more low voltage capacitors electrically coupled in series to the one or more high voltage capacitors to form a capacitive voltage divider. The sensor also includes a low voltage connection configured to provide a low voltage signal corresponding to a high voltage signal present in the separable connector, the low voltage connection comprising a coaxial contact having a first metal contact and a second metal contact.

Abstract: Techniques, systems and articles are described for monitoring electrical equipment of a power grid and predicting likelihood failure events of such electrical equipment. In one example, a system includes an article of electrical equipment, at least one processor, and a storage device. The article of electrical equipment includes one or more sensors that are configured to generate sensor data indicative of one or more conditions of the article of electrical equipment. The storage device includes instructions that, when executed by the at least one processor, cause the at least one processor to: receive the sensor data; determine, based at least in part on the sensor data, a health of the article of electrical equipment; and responsive to determining the health of the article of electrical equipment, perform an operation.

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.
