Patent ID: 10003383

Abstract:
Power transmission system (1) for power transmission of electric power (P) from a power source (2A) to a power sink (4A) which is connected to the power source (2A) via a power transfer cable (3), wherein the power source (2A) has a first pole with a first electric potential, which is connected via parallel current lines of a first conducting pair of the power transfer cable (3) to a first pole of the power sink (4A), and a second pole with a second electric potential, which is connected via further parallel current lines of a second conducting pair of the power transfer cable (3) to a second pole of the power sink (4A), wherein, during the power transmission via the current lines, a user data signal can be transmitted between the power source (2A) and the power sink (4A) via at least one conducting pair with current lines of the same electric potential, uninfluenced by the power transmission.
