Abstract

Transformateur de mesure de courant ou de tension. Ce transformateur est constitué par un conducteur de mesure 2 conduisant le courant de mesure Im , par un enroulement de prémagnétisation 3 conduisant un courant de prémagnétisation Iv et par un comparateur de champs magnétiqus exposé au champ magnétique engendré par le courant à mesurer Im et par le courant de prémagnétisation Iv et commandé alternativement dans les deux sens de saturation. Le comparateur de champs magnétiques est une pellicule magnétique 5 de très faible épaisseur. La pellicule magnétique 5 peut être anisotrope, peut être excitée dans la direction magnétique préférentielle et peut présenter une épaisseur maximale de quelques microns Ce transformateur de mesure peut servir de transformateur d'entrée dans un compteur d'électricité statique.
