Abstract

EL INVENTO SE REFIERE A LA MEDICION DE LAS TENSIONES. TIENE POR OBJETO UN DISPOSITIVO DE MEDICION DE LAS TENSIONES DE UNA INSTALACION TRIFASICA ESPECIALMENTE DEL TIPO BLINDADO, QUE CONSTA PARA CADA UNO DE LOS CONDUCTORES DE FASE DE UN DIVISOR CAPACITIVO DOTADO DE UN PRIMER CONDENSADOR CONECTADO, POR UNA PARTE, A DICHO CONDUCTOR Y, POR OTRA, A UN SEGUNDO CONDENSADOR CONECTADO A LA MASA, CARACTERIZADO PORQUE LA TENSION (V1,V2,V3) DE CADA UNO DE LOS SEGUNDOS CONDENSADORES (C''1,C''2,C''3) DE LOS DIVISORES SE APLICA, RESPECTIVAMENTE, POR UNA PARTE A LA ENTRADA DE UN INVERSOR (I1,I2,I3) Y, POR OTRA, MEDIANTE UNA PRIMERA RESISTENCIA (R1,R2,R3) A LA ENTRADA NEGATIVA DE UN AMPLIFICADOR OPERACIONAL (A1,A2,A3) ENLAZADO IGUALMENTE, A TRAVES DE LAS SEGUNDAS (R21,R12,R13) Y TERCERAS (R31,R32,R23) RESISTENCIAS. APLICACION EN LAS LINEAS TRIFASICAS.
