Abstract
Official abstract text for this publication.
Sensored cable ( 1 ) for distribution of electrical power in a power network, the sensored cable comprising an inner conductor and an insulating layer ( 10 ) arranged concentrically around at least an axial section of the inner conductor. The sensored cable further comprises a capacitive voltage sensor ( 100 ) for sensing a voltage of the inner conductor, characterized by the sensor including a printed circuit board element ( 60 ), which is placed over an electrically isolated piece ( 140 ) of conductive or semiconductive material, arranged on the insulating layer of the cable. The electrically isolated piece ( 140 ) of conductive or semiconductive material is operable to form an electrode of a sensing capacitor of the capacitive voltage sensor. The cable may comprise a (semi-) conductive layer ( 20 ). The electrically isolated piece ( 40 ) of conductive or semiconductive material may comprise a portion of the (semi-) conductive layer.
First claim

The invention claimed is: 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. 2. Sensored cable according to claim 1 , wherein the printed circuit board element comprises a double-sided printed circuit board. 3. Sensored cable according to claim 1 , wherein the printed circuit board element comprises an exposed conductive region providing an extended two-dimensional surface contact area, wherein the exposed conductive region is in mechanical and electrical contact with the electrically isolated piece of conductive or semiconductive material in two dimensions and over an extended area. 4. Sensored cable according to claim 3 , wherein the exposed conductive region provides a continuous surface contact area or a patterned surface contact area. 5. Sensored cable according to claim 3 , wherein the printed circuit board element comprises a flexible portion, and wherein the exposed conductive region is arranged on the flexible portion. 6. Sensored cable according to claim 1 , wherein the cable comprises a conductive or semiconductive layer, arranged concentrically on at least a portion of the insulating layer, and wherein the electrically isolated piece of conductive or semiconductive material comprises a first portion of the conductive or semiconductive layer.
