Abstract

LOS INTERRUPTORES DE PROTECCION DE CORRIENTE DE FALLOS HABITUALES MUESTRAN UNA TECLA DE PRUEBA A SER ACCIONADA MANUALMENTE. UN DESARROLLO POSTERIOR FUE LA TECLA DE PRUEBA ACCIONADA DE FORMA AUTOMATICA, QUE SIN EMBARGO TIENE LAS MISMAS DESVENTAJAS QUE EL ACCIONAMIENTO MANUAL, YA QUE SE RECONOCE EL DEFECTO DE INTERRUPTOR, DE TAL MODO QUE NO ES CAPAZ DE FUNCIONAMIENTO AL MENOS DURANTE UN TIEMPO LARGO. EL INTERRUPTOR DE PROTECCION DE CORRIENTE DE FALLO CON SUPERVISION AUTOMATICA DE ACUERDO CON LA INVENCION REPRESENTA UN INTERRUPTOR, QUE RECONOCE UN DEFECTO QUE SE INICIA DE FORMA PRECOZ, PARA PODER CAMBIAR EL INTERRUPTOR AUN EN EL TIEMPO ADECUADO. ESTO SE ASEGURA DE TAL MODO, QUE CON LA AYUDA DE UN TRANSMISOR DE CORRIENTE Y UN SENSOR DE CORRIENTE SE ACUMULA SU VALOR DE REACCION DE CORRIENTE DE FALLO Y SE MIDE EN UNA DISTANCIA DE TIEMPO PREVIAMENTE DADA. A PARTIR DEL AUMENTO TEMPORAL DEL VALOR DE REACCION SE EXTRAPOLA EL VALOR DE REACCION TEORICO Y CON ELLO SE DETERMINA EL PUNTO DEL TIEMPO, QUE APARECE EN EL INTERRUPTOR.
