A current converter unit for a high-voltage direct-current (HVDC) transmission contains a first converter and a second converter. A first direct-current terminal of the first converter is connected to a first conductor terminal point for a first HVDC transmission conductor. A second direct-current terminal of the first converter is connected to a first direct-current terminal of the second converter such that a connection point is formed. A second direct-current terminal of the second converter is connected to a second conductor terminal point for a second HVDC transmission conductor. The connection point is connected to ground potential by a current-damping electric component, and the connection point is connected to the ground potential by a direct-current switch.
