Claim:
1. Sensored cable for distribution of electrical power in a power network, the sensored cable comprising: an inner conductor and an insulating layer arranged concentrically around at least an axial section of the inner conductor; and a capacitive voltage sensor for sensing a voltage of the inner conductor, wherein the sensor includes a printed circuit board element placed over an electrically isolated piece of conductive or semiconductive material, the electrically isolated piece of conductive or semiconductive material being arranged on the insulating layer of the cable and being operable to form an electrode of a sensing capacitor of the capacitive voltage sensor, wherein the cable comprises additional conductive or semiconductive material comprising two conductive or semiconductive axial sections, and wherein the additional conductive or semiconductive material is arranged on either side of the electrically isolated piece of conductive or semiconductive material, one or both of the two axial sections of the additional conductive or semiconductive material being electrically isolated from the electrically isolated piece of conductive or semiconductive material by non-conductive axial sections.
