Abstract

LA PRESENTE INVENCION SE REFIERE A UN DISPOSITIVO (2) DE DETECCION DE FALLOS EN UNA REA AEREA DE DISTRIBUCION DE ENERGIA ELECTRICA QUE COMPRENDE , UNA CAJA (4) SOLIDARIA AL SOPORTE DE LINEA (6), UN CIRCUITO ELECTRONICO (8) CONECTADO A AL MENOS UN PRIMER DETECTOR (10) SENSIBLE A LAS VARIACIONES TRANSITORIAS DE LA CORRIENTE HOMOPOLAR DE LA LINEA QUE HAY QUE VIGILAR Y A AL MENOS UN SEGUNDO DETECTOR (12) SENSIBLE A LAS VARIACIONES TRANSITORIAS DE LA TENSION HOMOPOLAR DE DICHA LINEA, EFECTUANDO DICHO CIRCUITO ELECTRONICO (8) UNA DETECCION DE FALLO BASADA EN LA COMPARACION DE SIGNOS DE DICHAS VARIACIONES TRANSITORIAS DE LAS CORRIENTES HOMOPOLARES Y DE DICHAS VARIACIONES TRANSITORIAS DE LAS TENSIONES HOMOPOLARES. SEGUN LA INVENCION, LA CAJA (4) INCLUYE AL MENOS UN ELEMENTO CONDUCTOR (14) DESTINADO A PROPORCIONAR UNA ORIENTACION CONOCIDA A LAS LINEAS DE CAMPO ELECTRICO CERCA DE DICHO SOPORTE (6) DE LA LINEA QUE HAY QUE VIGILAR.
