Abstract

Un dispositivo (1) para medir corriente eléctrica compuesto de una pluralidad de elementos de sensor de campo magnético (2, 2.1, 2.2,..., 2.n) colocados alrededor de un conductor con carga de corriente, donde cada elemento de sensor es sensible a un componente de vector del campo magnético generado por la corriente eléctrica, donde los elementos de sensor (2, 2.1, 2.2,..., 2.n) están colocados a lo largo de una o más trayectorias cerradas continuas que rodean el conductor, diferenciándose porque los elementos de sensor individuales (2, 2.1, 2.2,..., 2.n) en la misma trayectoria tienen diferentes sensibilidades, o sus señales de salida son amplificadas por diferentes factores de ganancia antes que sean combinadas para formar la señal de sensor, y/o elementos de sensor (2, 2.1, 2.2,..., 2.n) no están distribuidos de manera uniforme a lo largo de las trayectorias, por ejemplo, teniendo una concentración superior de elementos en las inmediaciones de un cierto eje de sensor y las señales de salida de los elementos individuales (2, 2.1, 2.2,..., 2.n) son electrónicamente combinadas para generar la señal de salida del sensor de corriente, de manera que el dispositivo de medición de corriente (1) tiene una sensibilidad a la diafonía muy reducida con respecto a ciertas trayectorias de corriente.
