SENSORED CABLE FOR A POWER NETWORK

摘要

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.
