Resumen
Method of locating ground faults in armature windings of synchronous machines, comprising: - supply with direct voltage (3) of the inductor winding (1) with the machine rotating; - measurement of the voltage induced in the phase or branch with defect (8) with respect to earth, being disconnected from the grounding of the synchronous machine (4); - measurement of an induced voltage in the phases without defect (6, 7); - calculation of the percentage of the amplitude of the voltage induced in the phase or branch with ground fault (8) with respect to the voltage induced in any of the healthy phases or branches (6, 7); - calculation of the percentage of the winding where the ground fault is based on the percentage of the voltage amplitude induced in the phase with ground fault (8) with respect to the voltage induced in any of the phases or healthy branches (6, 7).
