摘要
A dc connection (CAB1, CAB2) in a bipolar 12-pulse system for transmission of electrical energy by means of high-voltage direct current interconnects two converters, each one having two 6-pulse valve bridges (BR11, BR12, BR21, BR22) connected in series at a connection point (J1, J2). In a method for location of the cable, said cable is located by sensing of a magnetic field associated with a current flowing through the cable. The dc connection is temporarily supplied with a ground-mode current, intended for the location, and a magnetic field associated with said ground-mode current is sensed.
