Abstract

LA INVENCION SE REFIERE A UN METODO PARA LA MEDICION DE LA CORRIENTE ALTERNA, UN DETECTOR DE MEDICION PARA MEDIR LA CORRIENTE ALTERNA, Y A LA UTILIZACION DE DICHO DETECTOR DE MEDICION EN UN CONTADOR DE KILOVATIOS/HORA. EN EL METODO, DENTRO DE UN SISTEMA CONDUCTOR DE CORRIENTE (30A) O EN INMEDIATA VECINDAD DEL CITADO SISTEMA, SE ACOPLA UN GRADIENTIMETRO DE PRIMERA CATEGORIA COMO MINIMO, EN CUYO CASO LA CORRIENTE QUE CIRCULA EN EL SISTEMA CONDUCTOR DE CORRIENTE (30A) INDUCE UNA TENSION EN EL GRADIENTIMETRO, ESTANDO LA FORMA DEL SISTEMA CONDUCTOR DE CORRIENTE (30A) Y LA FORMA DE LA ESTRUCTURA DE LA ESPIRA DEL GRADIENTIMETRO (20A) ADAPTADAS ENTRE SI, DE MODO QUE LA SEÑAL RESULTANTE SEA SUBSTANCIALMENTE INDEPENDIENTE DE TODO PEQUEÑO CAMBIO QUE TENGA LUGAR EN LAS POSICIONES RELATIVAS DEL SISTEMA CONDUCTOR DE CORRIENTE (30A) Y EL GRADIENTIMETRO (20A).
