Abstract

L'invention concerne un dispositif de mesure du courant électrique circulant dans un conducteur électrique au moyen d'un dispositif de mesure situé à proximité du conducteur électrique et mesurant le champ magnétique généré par le courant électrique, dans lequel : le dispositif de mesure comprend un dispositif capteur magnétique captant le champ magnétique selon au moins deux directions spatiales orthogonales ; le dispositif de capteur magnétique comprend des transducteurs ou des capteurs qui sont sensibles aux champs magnétiques et attribués auxdites deux directions spatiales orthogonales au moins ; et le courant peut être déterminé à partir des valeurs de mesure capturées par le dispositif de capteur magnétique.
