Resumen
System and method for locating ground faults in excitation windings of synchronous machines with indirect excitation based on grounding the neutral of the armature winding of the exciter machine by means of a high ohmic value impedance. The system and method determine the position of the fault by analyzing the voltage in the grounding impedance and the excitation current of the excitation machine, thanks to the calculation of the voltage components in the excitation winding of the synchronous machine. .
