Abstract

Sistema de protección contra fallo de toma de tierra de un arrollamiento de una máquina eléctrica (1), en la que está integrada una derivación de toma de tierra conectada con el punto neutro (N) del arrollamiento, en la que está conectada una resistencia (6) de baja impedancia, que está conectada paralelamente a una fuente de tensión (9) con una frecuencia igual a 1/4 de la frecuencia nominal de la máquina (1) y donde la fuente (9) de esta tensión está acoplada con una unidad de protección contra fallo de toma de tierra (8), cuyas salidas están conectadas en el arrollamiento secundario de un transformador de tensión (7) y el arrollamiento primario del transformador de tensión (7) está conectado en la derivación de toma de tierra, caracterizado porque en el circuito de corriente, formado por el arrollamiento primario del transformador de tensión (7) y la derivación de toma de tierra (2), entre el punto neutro (N) del arrollamiento de la máquina (1) y la resistencia de baja impedancia (6) está conectada en paralelo una bobina de reactancia de derivación (5).
