Abstract

Un circuito transformador de corriente tipo toroidal de una sola bobina para detectar corriente de CA y CD. El circuito transformador de corriente puede incluir un transformador de corriente y un oscilador eléctricamente conectado al transformador de corriente. El circuito transformador de corriente además puede incluir un circuito de detección de CT abierto y corto conectado eléctricamente al oscilador para facilitar la determinación de estado de conexión y estabilidad del transformador de corriente. Un procesador puede conectarse de manera eléctrica a una salida del circuito de detección de CT abierto y corto para realizar una serie de operaciones sobre datos de señales generados por el circuito de detección de CT abierto y corto y manipular la operación de un sistema de energía eléctrica por consiguiente.
