Abstract

Método y sistema para la detección de faltas a tierra en sistemas de corriente continua alimentados mediante un rectificador.#La presente invención se refiere a un método y un sistema para la detección de faltas a tierra en sistemas de corriente continua alimentados mediante un rectificador y un transformador. La invención comprende: obtener una señal de tensión en una impedancia de puesta a tierra conectada al transformador; obtener una segunda señal de tensión entre uno de los terminales del rectificador y el neutro del transformador; realizar una comparación angular entre los vectores de tensión correspondientes a ambas señales de tensión; y determinar si existe una falta en función de un umbral preestablecido.Method and system for detecting ground faults in DC systems powered by a rectifier. # The present invention relates to a method and system for detecting ground faults in DC systems powered by a rectifier and a transformer. The invention comprises: obtaining a voltage signal at a grounding impedance connected to the transformer; obtain a second voltage signal between one of the rectifier terminals and the transformer neutral; make an angular comparison between the voltage vectors corresponding to both voltage signals; and determine if there is a fault based on a preset threshold.
