Resumen
System and method of locating earth faults in stator windings of synchronous machines grounded by a high-value impedance. The present invention is directed to a method of locating ground faults in the stator of a synchronous machine, for example a generator, and to a power generation plant for feeding an electrical network. The method is based mainly on the location of the fault by using variables obtained in the measurement stage and the estimated defect resistance value. The obtaining of the resistance of defect is carried out through the information that provides a system of injection of tension in the resistance of ground to low frequency.
