Abstract
EL INSTRUMENTO TRANSFORMADOR DE MEDICION CONSISTE EN UN NUCLEO FERROMAGNETICO (2, 6) DE TRES RAMAS O TRAMOS, CUYO TRAMO CENTRAL O MEDIO (6) POSEE TRES ENTREHIERROS (7, 8, 9) Y ESTA RODEADO, AL MENOS PARCIALMENTE, POR UN CONDUCTOR ELECTRICO (1). EN EL ENTREHIERRO CENTRAL (7) ESTA DISPUESTO UN DETECTOR DE CAMPO MAGNETICO (3), MIENTRAS QUE LOS DOS ENTREHIERROS EXTERIORES (8, 9) ESTAN DISPUESTOS CADA UNO DE LOS DOS EXTREMOS DEL TRAMO MEDIO (6). EL TRAMO MEDIO (6) Y EL DETECTOR DE CAMPO MAGNETICO (3) FORMAN CONJUNTAMENTE UNA CONSTRUCCION UNITARIA. CADA UNO DE LOS DOS ENTREHIERROS EXTERIORES (8, 9), MEDIDO EN LA DIRECCION LONGITUDINAL DEL TRAMO MEDIO (6), ES PREFERIBLEMENTE MAS LARGO QUE EL ENTREHIERO MEDIO (7). ESTA CONSTRUCCION PERMITE UN MONTAJE ESPECIALMENTE PRECISO, SENCILLO Y SEGURO DEL INSTRUMENTO TRANSFORMADOR DE MEDICION, SIN PERJUDICAR POR ELLO LA LINEALIDAD, EL ERROR DE FASE Y LAS TOLERANCIAS DE ENTREHIERRO DEL INSTRUMENTO TRANSFORMADOR DE MEDICION.
