Abstract

DIVISOR DE CORRIENTE PARA TRANSFORMADORES DE MEDIDA PARA LA MEDICION EXENTA DE POTENCIAL DE CORRIENTES.CONSTA DE UN CONDUCTOR DE CORRIENTE CON DOS CIRCUITOS DE CORRIENTE, UNO DE LOS CUALES (1) CONDUCE LA CORRIENTE DERIVADA A MEDIR Y EL OTRO (2) CIRCUITO DE CORRIENTE FORMA UNA DERIVACION. LA DERIVACION (2) ESTA COMPUESTA POR UN CONDUCTOR PLANO CON BRAZOS (4, 5) QUE TRANSCURREN PARALELOS. EL CIRCUITO DE CORRIENTE DE MEDIDA (1) ESTA FORMADO POR CONDUCTORES DE MEDIDA EN FORMA DE Z CON CONDUCTORES (10, 11, 12, 13) PARALELOS A LOS BRAZOS (4, 5) Y CON SENDAS PARTESTRANSVERSALES (14, 15) LOS CUALES ESTAN DISPUESTOS EN LAS PAREDES INTERIORES DE LOS BRAZOS (4, 5) Y ESTAN UNIDOS ELECTRICAMENTE CON ESTOS MEDIANTE LOS EXTREMOS DE LOS CONDUCTORES. LAS PARTES TRANSVERSALES FORMAN UN ALMA (16) QUE ESTA RODEADA POR UN NUCLEO (17) DE UN TRANSFORMADOR DE MEDIDA EN UNAS ABERTURAS (6, 7) PREVISTAS EN LOS BRAZOS (4, 5).
