Abstract

APARATO PARA DETECTAR CIERTAS CONDICIONES DEFECTUOSAS DE CARGA DE CARGAS DE TUBOS LUMINOSOS GASEOSOS CONECTADOS A VOLTAJES ALTOS, SUMINISTROS DE POTENCIA DE FRECUENCIA ALTA QUE INCLUYEN CIRCUITO ABIERTO, TUBO ROTO Y OTRAS CONDICIONES DEFECTUOSAS DE CARGA EQUILIBRADA. EL DETECTOR INCLUYE UN FILTRO PARA RECALCAR EL CONTENIDO ARMONICO DE LA SALIDA DE SUMINISTRO DE POTENCIA, UN ATENUADOR, UN COMPARADOR U OTRO DISPOSITIVO DETECTOR/UMBRAL, Y UN CIRCUITO DE RETANSMISION. UN INTERRUPTOR DE CIERRE DE SUMINISTRO DE POTENCIA PUEDE INCLUIRSE O EL PRESENTE DETECTOR DE DEFECTOS PUEDE INTERCONECTARSE AL INTERRUPTOR DE CIERRE DE UN INTERRUPTOR DE DEFECTOS DE TIERRA CONVENCIONAL. EN UNA PUESTA EN PRACTICA EL FILTRO Y EL ATENUADOR Y, EN OTRO, EL FILTRO, ATENUADOR Y UN CIRCUITO DE RETRANSMISION EMPLEAN COMPONENTES COMUNES Y PUEDEN INCLUIR UB CAPACITOR FLTRO/ATENUADOR DEFINIDO POR COLOCACION DE METALIZACION SOBRE EL TRANSFORMADOR DE SUMINISTRO DE POTENCIA A ALTA FRECUENCIA ADYACENTE A UNA CARGA DE SALIDA DE VOLTAJE ALTO.
