A data signal in a powerline system is inductively coupled between a service line (1) and a signal line (11) connected to a transmitter/receiver (10.1). Coupling ferrites (12.1, 12.2) are arranged around two phase conductors (2.2, 2.3) of the service line (1). The signal conductors (11.1, 11.2) of the signal line (11) are fed through the holes of said coupling ferrites (12.1, 12.2) in the form of a loop and are then connected to each other. A data signal transmitted from the transmitter/receiver (10.1) to the signal line (11) can be coupled to the two phase conductors (2.2, 2.3) of the service line (1) by means of the inventive coupling device. The whole process is of course reversible. |
