Abstract

SE PRESENTA UN DETECTOR DE CIRCUITOS AVERIADOS (10) QUE TIENE UN INDICADOR ELECTRICAMENTE AISLADO Y POSICIONADO DE FORMA REMOTA (14), EL DETECTOR DETECTA FALLOS EN LA CORRIENTE DE UN CONDUCTOR (18). CUANDO SE DETECTA UN FALLO DE UNA MAGNITUD PREDETERMINADA, SE TRANSMITE UN IMPULSO DE LUZ DESDE EL DETECTOR HASTA EL INDICADOR POR MEDIO DE UN CABLE DE FIBRA OPTICA (16) EN EL QUE, DESPUES DE RECIBIDO, SE CONVIERTE EL IMPULSO EN UN IMPULSO ELECTRICO QUE HACE QUE EL INDICADOR INDIQUE UN ESTADO DE FALLO. UN CIRCUITO DE RESETEO (56) DENTRO DEL INDICADOR RESETEA EL INDICADOR A INTERVALOS REGULARES PONIENDOLO EN UN ESTADO NORMAL TAN PRONTO COMO ESTE PRESENTE UN PREDETERMINADO VOLTAJE MINIMO SOBRE EL CONDUCTOR MONITORIZADO. EL DETECTOR INCLUYE UN CIRCUITO DE COMPENSACION DE TEMPERATURA (150) Y UN CIRCUITO DE FILTRO DE PASO BAJO (160) PARA EVITAR EL FUNCIONAMIENTO ERRONEO DEBIDO A LA VARIACION DE LAS TEMPERATURAS DEL AMBIENTE O A LA PRESENCIA DE ALTAS FRECUENCIAS. TAMBIEN SE SUMINISTRA UN CIRCUITO DE PRUEBA (48, 50, 34) QUE PERMITE AL PERSONAL DE SERVICIO REALIZAR UNA PRUEBA DE CAMPO DEL DISPOSITIVO CON EL CONDUCTOR MONITORIZADO EN ESTADO DE FUNCIONAMIENTO.
