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.
