Abstract (en)
The rotation machine (39) has a slip ring on a shaft (40) and a brush that can be brought into contact with the slip ring. The arrangement has a measurement and evaluation device with a distance sensor arranged close to the slip ring surface for determining variations in the slip ring from a distance measurement between the distance sensor and the slip ring surface. Independent claims are also included for the following: (a) a turbogenerator (b) and a method of measuring and evaluating faults or damage in or to a slip ring of an electrical rotation machine.
