Abstract

Se muestran sistemas y métodos para detectar un fusible fundido en una línea trifásica al comparar puntos neutrales en la línea antes y después de los fusibles. Circuitos rectificadores de diodo pueden utilizarse para comparar los puntos neutrales y generar un voltaje de salida de CD cuando los puntos neutrales estén desplazados entre sí, y circuitos fotoacopladores pueden proporcionar aislamiento eléctrico cuando señalen un cambio de punto neutral. Los puntos neutrales comparados no necesitan estar en lados inmediatos de los fusibles, de manera que pueden existir componentes intermedios, y en algunas modalidades uno de los puntos comparados puede estar dentro de una carga conectada a la línea trifásica.
