Abstract
L'invention concerne un transformateur de mesure comportant un enroulement primaire parcouru par un courant devant être mesuré. Dans ce transformateur de mesure, comportant un enroulement primaire 1 traversant un noyau de fer 2 sur lequel est monté un enroulement secondaire aux extrémités 4, 5 duquel est raccordée une résistance ohmique 6, cette dernière peut etre commutée, en fonction des valeurs nominales différentes du courant à mesurer J, sur différentes valeurs telles que, pour des valeurs nominales différentes du courant J, une tension de même valeur U chute aux bornes de la résistance 6. Application notamment à la mesure de courants intenses.The invention relates to a measuring transformer comprising a primary winding through which a current to be measured is carried. In this measuring transformer, comprising a primary winding 1 passing through an iron core 2 on which is mounted a secondary winding at the ends 4, 5 of which is connected an ohmic resistor 6, the latter can be switched, according to the different nominal values of the current to be measured J, on different values such that, for nominal values different from current J, a voltage of the same value U drops across resistor 6. Application in particular to the measurement of intense currents.
