Claim Text:
1. A slip-ring unit for transmitting an electric current, comprising: a first component group; a second component group, the two component groups arranged in a manner allowing rotation relative to each other about an axis; a first track; a second track; a brush; and a slip ring, the brush and the slip ring arranged to contact each other over different rotational positions along one of the tracks; wherein the first component group includes a first connection terminal and an electric circuit adapted to monitor conditions; wherein the second component group includes a second connection terminal; wherein the electric current is transmittable from the first connection terminal to the second connection terminal over the first track; wherein an electric voltage is transmittable over the second track to the circuit; wherein the first track and the second track are connected electrically; and wherein the circuit includes a current source adapted to generate a testing current, and the slip-ring unit is configured such that the testing current flows over the first track and the second track, the circuit being closable by a switching device, triggered by a signal from an arithmetic logic unit.
