Abstract

La presente invención comprende, entre otros, un sensor de Rogowski (10) para medir una corriente (Il(t)) de un conductor (90) con una bobina de Rogowski (20) que presenta una resistencia eléctrica de devanado (Rr) y un dispositivo de integración unido a la bobina de Rogowski, para generar una señal de salida (Ua(t)) proporcional a la corriente eléctrica (Il(t)) por medir con el censor de Rogowski. Acorde a la invención, está previsto que el dispositivo de integración esté formado por la resistencia de devanado (Rr) de la bobina de Rogowski (20) y un capacitor (Ci) unido a una de las dos conexiones de devanado (50, 60) de la bobina de Rogowski y la señal de salida del dispositivo de integración es formada por la tensión (Ua(t)) que se halla en el capacitor (Ci).
