Resumen

Method and system for the detection of ground faults in dc systems powered by a rectifier. The present invention relates to a method and a system for the detection of ground faults in dc systems powered by a rectifier and a transformer. The invention comprises: obtaining a voltage signal in a grounding impedance connected to the transformer; obtain a second voltage signal between one of the terminals of the rectifier and the neutral of the transformer; perform an angular comparison between the voltage vectors corresponding to both voltage signals; and determine if there is a fault based on a pre-established threshold.
