Abstract
Electrode foil (6) comprising a) an electrode layer (60) comprising—a sensing electrode portion (100), operable as an electrode of a sensing capacitor for sensing a voltage of an inner conductor (20) of a medium or high voltage power cable (10),—a first auxiliary electrode portion (200), electrically isolated from the sensing electrode portion. The electrode foil further comprises b) a non-conductive carrier film (71) carrying both the sensing electrode portion and the first auxiliary electrode portion, and c) an adhering surface portion (90) for attaching the electrode foil to an exposed insulation layer (30) of the power cable.
