Abstract
L'invention concerne un ampèremètre. Dans cet ampèremètre, qui comporte un dispositif d'affichage 11 pour l'intensité courant relié à un capteur de mesure 2 et à un transformateur d'intensité de saturation 6, par l'intermédiaire d'un convertisseur analogique-numérique 10, ces différents éléments sont réunis pour former un module 12 qui est associé directement au conducteur 1 véhiculant le courant à mesurer J. Application notamment à la mesure de courants de conducteurs à haute tension.
