Abstract

Apparatus for sensing a high-frequency event signal in a rotating electrical machine includes a HF evaluation apparatus, and at least two sensors arranged in the rotating electrical machine and designed to sense a low-frequency sensor signal. Each of the at least two sensors Includes an antenna for decoupling the high-frequency event signal from a high-frequency electromagnetic field of the rotating electrical machine. A common coupling element connects the at least two sensors to the HF evaluation apparatus. The coupling element designed to transfer the high-frequency event signal from at least one of the at least two sensors to the HF evaluation apparatus and to decouple the low-frequency sensor signal.
