Abstract

Se proporciona un sistema de interruptor de circuito con conexión a tierra que proporciona activación confiable y oportuna de circuitos con falla mientras disminuye la llamada activación "molesta". El GFCI incluye un dispositivo de detección de desequilibrio de voltaje unido al circuito de transmisión principal para detectar un desequilibrio de voltaje durante una condición de falla. Se programa un procesador de computadora en comunicación con el dispositivo de detección de desequilibrio de voltaje para determinar cuándo existe una condición de falla real en un estado de desequilibrio de voltaje y ciertos predeterminados a lo largo de las señales de falla generadas por la unidad de GFCI en el circuito de transmisión principal y las señales de falla generadas por las unidades de GFCI en los circuitos de alimentación individuales.
