Abstract

UN SISTEMA ES PROPORCIONADO PARA MONITORIZAR UN CABLE DE COMUNICACIONES (10) POR PENETRACION DE HUMEDAD. UN GENERADOR DE SEÑALES EN LINEA (14) ES CONECTADO A UN COMPONENETE METALICO INTEGRAL (18) DEL CABLE PARA APLICAR UNA SEÑAL EN LINEA AL COMPONENTE METALICO Y UN CAMINO DE RETORNO EN TIERRA COMO CIRCUITO DETECTOR DE HUMEDAD. LOS CAMBIOS EN LA SEÑAL EN LINEA SON MONITORIZADOS PARA DETECTAR LA CONDICION DEL CABLE. EL ELEMENTO METALICO DEL CABLE PUEDE SER UNA CAPA DE BLINDAJE DEL CABLE, PERMITIENDO LA MONITORIZACION DE LA PENETRACION DE LA HUMEDAD POR TODA LA LONGITUD DEL CABLE. EN UNA PARTICULARMENTE VENTAJOSA REALIZACION, UNA CAPA DE BLINDAJE ES MANTENIDA EN UN POTENCIAL CON EL SUELO REPECTIVO. ESTO PROPORCIONA UNA PROTECCION ANODICA ADICIONAL AL CABLE.
