Abstract: A conductor assembly for a power network includes an inner conductor, an insulating layer arranged concentrically around the inner conductor, and a sensing electrode, arranged radially outward of the insulating layer, and operable as a first electrode of a sensing capacitor of a voltage sensor. The conductor assembly further includes a voltage pickup element having electrically conductive major surfaces, the first major surface being in a surface contact with the sensing electrode. The conductor assembly further includes an electrode wire, in electrical and mechanical contact with the voltage pickup element, for electrically connecting the voltage pickup element with an electric or electronic component disposed remote from the sensing electrode.

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.
