Abstract

Perfeccionamientos en los interruptores de protección de corriente de defecto, con un transformador de intensidad sumaria con por lo menos un arrollamiento primario, un arrollamiento secundario que alimenta el arrollamiento de un disparado, y con un condensador, mediante el cual , aproximadamente a la frecuencia de la red, la inductividad de los arrollamientos del transformador de intensidad sumaria y del disparador está aproximadamente compensada, caracterizados porque el condensador (9) está conectado con un arrollamiento terciario (3) del transformador de intensidad sumaria cuyo número de espiras es un múltiple del número de espiras del arrollamiento secundario (2)
