Abstract

A conductor assembly for a power network includes an inner conductor defining radial and axial directions, an insulating layer arranged around at least an axial section of the inner conductor, and a sensing electrode arranged radially outward of the insulating layer. The sensing electrode is operable as a first electrode of a sensing capacitor of a capacitive voltage sensor, in which sensing capacitor the inner conductor is operable as a second electrode. The conductor assembly further includes an electrically insulating spacer element arranged radially between the insulating layer and the sensing electrode.
