Abstract:
A network comprising at least two lines (1, 2) and network users (3, 4, 5, 6), characterized in that the two lines (1, 2) of the network are formed both for data transfer among the network users (3, 4, 5, 6) and for energy transfer from a voltage source to the network users (3, 4, 5, 6), in that the data are symmetrically and differentially transferred through the two lines (1, 2), in that a terminal of the voltage source is coupled to the two lines (1, 2), in that the network users (3, 4, 5, 6) are coupled to the other terminal of the voltage source via a different electric connection separated from the network, in that the network users (3, 4, 5, 6) symmetrically couple out the energy transfer via the two lines (1, 2) of the network, and in that the two lines (1, 2) are mutually insulated.
