Abstract
A method for transmitting data via a traction current conductor which simultaneously conducts drive current for a vehicle and in which an interruption in the data transmission by an arc cccurring between a vehicle-end drive current collector and the traction current conductor is reliably avoided. The method for trandsmitting data via a traction current conductor, in which at the transmitter end at least two data signals including in each case the data in an identical form are fed into the traction current conductor with different frequency channels. In the event of an arc occurring at the receive end, the received data of that data signal or those data signals whose amplitude does not drop below a ratio necessary for achieving a specific bit error probability with respect to the amplitude of the interference signal S(f), is selected for evaluation.
