Abstract

DONDE DICHO APARATO GENERA, EN UNA CARGA ELECTRICA DE FASES MULTIPLES PROVISTA CON UN PRIMER PUNTO NEUTRAL ARTIFICIAL, UNA SENAL DE CONTROL INDICATIVA DE LA CORRIENTE EN DICHO PUNTO; DONDE DICHA CARGA, INCLUYENDO UN TRANSFORMADOR, COMPRENDE UNA SERIE DE DEVANADOS PRIMARIOS CONECTADOS A LAS FASES DE ENTRADA INDIVIDUALES RESPECTIVAS DE LA CARGA ELECTRICA Y A DICHO PRIMER PUNTO. EL APARATO COMPRENDE: i) UN DISPOSITIVO QUE GENERA UN SEGUNDO PUNTO NEUTRAL ARTIFICIAL SIN CARGA ELECTRICA, PROVISTA DE: a) UNA SERIE DE DEVANADOS SECUNDARIOS CON TERMINALES CONECTADOS EN CONFIGURACION ESTRELLA AL PRIMER TERMINAL DE LA UNIDAD DETECTORA; Y, b) UNA SERIE DE IMPEDANCIAS, TAL COMO RESISTORES, CON TERMINALES CONECTADOS A LOS SEGUNDOS TERMINALES DE LOS DEVANADOS SECUNDARIOS, Y LOS OTROS TERMINALES CONECTADOS AL SEGUNDO TERMINAL DE UNA UNIDAD DETECTORA; Y, ii) UNA UNIDAD DETECTORA DE VOLTAJE CON UN TERMINAL DE ENTRADA CONECTADO A DICHO SEGUNDO PUNTO Y OTRO TERMINAL DE ENTRADA CONECTADO A UN PUNTO QUE TIENE UN VOLTAJE DE SECUENCIA CERO, DONDE LA SENAL DE SALIDA DE LA UNIDAD DETECTORA ES UNA SENAL DE CONTROL INDICATIVA DE LA CORRIENTE DEL PUNTO NEUTRAL. LA CARGA ELECTRICA PUEDE SER UN CONVERTIDOR DE CA/CC. ADEMAS SE REFIERE A UN METODO DE DERIVACION, EN LA CARGA ELECTRICA MENCIONADA
