Abstract

Un dispositivo electrónico perfeccionado destinado a ser conectado en un circuito de distribución de energía eléctrica de c.a. de múltiples hilos conductores, para producir una señal de salida relacionada con la energía eléctrica suministrada por un suministrador de energía eléctrica a un consumidor de energía eléctrica suministrada por un suministrador de energía eléctrica a un consumidor de energía eléctrica a través de dicho circuito de distribución, incluyendo dicho circuito de distribución al menos un hilo conductor vivo, incluyendo el dispositivo: al menos un par de terminales de intensidad de corriente, para conexión en serie en dicho hilo conductor vivo; medios de percepción de intensidad de corriente conectados entre dicho par de terminales de intensidad de corriente, para producir una señal representativa de la intensidad de corriente que circula por dicho hilo conductor vivo; y un circuito electrónico conectado para recibir la señal representativa de la intensidad de corriente, incluyendo dicho circuito electrónico medio para producir dicha señal de salida en respuesta a dicha señal representativa de la intensidad de corriente; y un suministro de energía eléctrica de c.c. para dicho circuito electrónico; en que los medios de percepción de la intensidad de corriente comprenden una derivación conectada en serie entre dicho par de terminales de la intensidad de corriente, el circuito electrónico está conectado para recibir el voltaje generado a través de la derivación, por caminos de circuito no inductivo de valor de resistencia relativamente bajo, e incluye todos los componentes activos, diodos inclusive si los hay, necesarios para derivar del circuito de distribución cualquier entrada a los medios productores de señales de salida, y el suministro de energía eléctrica de c.c. destinado a ser acoplado de modo no inductivo entre el hilo vivo y otro hilo del circuito de distribución, y está dispuesto para producir una salida de c.c. con respecto al hilo vivo, con lo quese hace flotar eléctricamente el circuito electrónico sustancialmente al voltaje del hilo vivo y de este modo se protege eficazmente a los componentes activos del circuito electrónico de perturbaciones en el circuito de distribución.
