Sažetak
This paper deals with detection of inter-coil short circuits in coils of the salient poles synchronous generator excitement winding on the basis of the analysis of the magnetic field in the machine. Applying FEM to the generator model, magnetic field wave forms in the machine, on the points of interests, under both, faultless and faulty conditions were calculated. When results were compared, changes in wave forms caused by the analyzed fault were identified. On the model, magnetic inductions and magnetic fields were calculated on the points accessible for measuring with Hall’ s sensors and measuring coils in the actual machine. The gold of this paper is a contribution in the field of identification of faults and failures in rotating machines, or, in other words, improvement of monitoring systems in charge of rotating machine condition monitoring.
