ABSTRACT:
The present invention concerns a synchronous machine with preferably salient poles with pole windings which are galvanically connected together. The invention further concerns a wind power installation and a method of monitoring a synchronous machine of a wind power installation. The object of the invention is to develop a synchronous machine and a method of operating a synchronous machine, such that the risk of a fire is reduced. A synchronous machine comprising a rotor which has a plurality of poles which are each provided with at least one respective pole winding, wherein the pole windings of a plurality of poles are galvanically connected together by means of a first conductor through which an exciter current flows, characterized in that laid substantially parallel to the first conductor is a monitoring conductor which is acted upon or which can be acted upon with a predeterminable signal, that the monitoring conductor is coupled or connected to a device for detecting the signal and that upon an interruption in the first conductor same is or can be detected by a signal variation in the monitoring conductor and the device for detecting the signal is coupled to a control device which then at least reduces and preferably switches off the exciter current through the first conductor.
