Abstract

Un interruptor de circuito de falla de tierra de alta corriente, tiene uncensor de inducción montado sobre el dispositivo, remoto del circuito delinterruptor de circuito de falla de tierra, de tal manera que permite quehaya cables capaces de llevar corrientes mayores que la capacidad parallevar corriente de los contactos del circuito del interruptor, parapasarse a través de los mismos. El censor de inducción lleva untransformador diferencial para detectar las fallas de la línea a latierra, y un transformador neutro para detectar las fallas del neutro a latierra. Hace uso de un contacto externo, cuya bobina está acopladamediante contacto del interruptor del circuito de falla de tierra, parainterrumpir los cables que llevan las altas corrientes, inclusive a unadistancia un poco remota del interruptor del circuito de falla de tierra.El censor de inducción tiene la capacidad para llevar a través del mismo,cables de una línea de corriente alterna de 240 voltios a tierra o delínea a línea.
