Abstract :
A diagnostic strategy for the monitoring of the transmission properties and sparking of doubly-fed induction generators with slip rings is introduced in this paper. Modifications in the transmission properties can be recognized by measurement and evaluation of the rotor currents without additional sensors. The existing current transformers in the system can be used for the diagnostic
