Abstract
Una disposición de circuito de protección contra corrientes de avería, que tiene un transformador totalizador de corriente cuyo primario consiste en los conductores principales de una red de corriente alterna o de corriente trifásica, cuyo secundario está unido con un desenganche o disparo, con una fuente de corriente para la producción de una pre magnetización por corriente alterna del transformador totalizador de corriente por medio de un devanado auxiliar, teniendo la corriente generada por la fuente de corriente una frecuencia que se aparta de la frecuencia de la red, con un circuito de prueba que deriva por medio de un pulsador una corriente de prueba desde la tensión de la red, caracterizado porque el devanado auxiliar del transformador totalizador de corriente está hecho como bobina de medición , la bobina de medición, junto con la fuente de corriente, está situada en la entrada de un órgano de filtro, aguas abajo del órgano de filtro está conectado un rectificador, el rectificador,por medio de un amplificador diferencial, está unido con un órgano semiconductor gobernable, y el órgano semiconductor gobernable está acoplado en paralelo con el pulsador del circuito de prueba.
