The invention relates to a measuring signal transmission device for transmitting signals between a rotating portion and a rotationally stationary portion, for example in a large electrical machine. The rotationally stationary portion is journalled to the rotating portion in such a way as to accompany the latter portion in its axial and radial movements, and light is arranged to be transmitted in both directions between the rotating portion and the rotationally stationary portion by light conductors at the center axis of rotation and/or at specified radii and at least one light-conducting fiber is located in the rotating portion and at least one light-conducting fiber is located in the rotationally stationary portion, whereby the light signal transmission is arranged to take place between fibers located at the same radii in both portions. |
