ABSTRACT:
An apparatus for monitoring a sliding contact element in an electrical rotating machine, in particular a generator, includes a holder for the sliding contact element and a sensor for detection of a state variable of the sliding contact element. An evaluation unit is also provided for evaluation of the state variable which is detected by the sensor, with signals from the sensor being transmitted to the evaluation unit without using wires. The wire-free transmission makes the apparatus particularly maintenance-friendly.
