Abstract

SE DESCRIBE UN APARATO PARA DETECTAR UNA DISCONTINUIDAD O UNA IRREGULARIDAD EN UNA LINEA NEUTRA DE RETORNO DE UNA RED DE DISTRIBUCION DE ENERGIA ELECTRICA QUE INCLUYE LA LINEA NEUTRA DE RETORNO, UNA LINEA ACTIVA Y UN RETORNO A TIERRA. EL APARATO INCLUYE MEDIOS PARA MEDIR UN CAMBIO DE VOLTAJE ASOCIADO CON UNA CONMUTACION DELIBERADA DE UNA IMPEDANCIA CONOCIDA EN LA RED ELECTRICA, DONDE EL CAMBIO DE VOLTAJE SE DEBE A UNA DISCONTINUIDAD O UNA IRREGULARIDAD EN LA IMPEDANCIA EN LA LINEA NEUTRA DE RETORNO Y MEDIOS PARA IMPLEMENTAR UN ALGORITMO PARA IDENTIFICAR LA DISCONTINUIDAD O LA IRREGULARIDAD EN LA IMPEDANCIA EN PRESENCIA DE VARIACIONES PERMISIBLES EN EL VOLTAJE NOMINAL DEL SUMINISTRO A LA RED ELECTRICA, INCLUYENDO LOS CAMBIOS DE VOLTAJE QUE RESULTAN DE OPERACIONES DE LA RED QUE IMITAN UN OCULTAN UNA DISCONTINUIDAD O UNA IRREGULARIDAD EN LA IMPEDANCIA EN LA LINEA NEUTRA DE RETORNO. EL APARATO TAMBIEN INCLUYE MEDIOS PARA COMPARAR UN RESULTADO DE LA MEDICION CON UNA REFERENCIA, PARA PROPORCIONAR UNA INDICACION DE LA DISCONTINUIDAD O LA IRREGULARIDAD EN LA IMPEDANCIA. TAMBIEN SE DESCRIBE UN METODO PARA DETECTAR UNA DISCONTINUIDAD O UNA IRREGULARIDAD EN LA LINEA NEUTRA DE RETORNO DE UNA RED DE DISTRIBUCION DE ENERGIA ELECTRICA.
