Abstract

EL SALTO DE CHISPA EN UN SISTEMA DE ALIMENTACION DE AC SE DETECTA MONITORIZANDO LA FORMA DE ONDA DE LA ENERGIA PARA EL RUIDO DE ALTA FRECUENCIA DE BANDA ANCHA, Y EXAMINANDO EL RUIDO DETECTADO PARA DETERMINAR LOS PATRONES DE VARIACION DE SU AMPLITUD SINCRONIZADA CON LA FORMA DE ONDA DE LA ENERGIA. SE PUEDE EMPLEAR UN DETECTOR DE FRECUENCIA DE BARRIDO DE BANDA ESTRECHA Y UN PROMEDIADOR SINCRONO PARA MEJORAR LA DISCRIMINACION DEL RUIDO DEL SALTO DE CHISPA DE LA INTERFERENCIA DE FONDO. SE DESCRIBE UN INTERRUPTOR PARA FALLOS POR SALTO CHISPA, PARA CONTROLAR UN CIRCUITO INDIVIDUAL, Y UN MONITOR PARA CASA GLOBAL, PARA DETECTAR EL SALTO DE CHISPA EN CUALQUIER LUGAR DE UNA CASA.
