This work presents an online diagnostic method for detecting shorted-turn faults in the field winding of synchronous generators, based on stator current measurements. The approach relies on a reference model of the generator’s healthy electromagnetic behavior, constructed using manufacturer-provide inductance values. During operation, current signals are processed using dimensionality reduction techniques (Principal Component Analysis, PCA), enabling identification of deviations from nominal behavior. Simulation results show that the method detects rotor faults without interrupting generator operation.
