Abstract
Dispositif pour la mesure du courant traversant un relais électronique statique qui est alimenté par l'enroulement secondaire d'un transformateur principal de courant, ce dispositif étant destiné à être connecté à l'entrée de mesure du courant dudit relais électronique. Ce dispositif comprend une résistance de dérivation 2 en parallèle avec l'enroulement secondaire 1 du transformateur de courant principal qui est dimensionné de telle manière que ledit enroulement secondaire 1 soit pratiquement court-circuité, la tension aux bornes de ladite résistance de dérivation 2 étant cependant suffisante pour être exploitable par ledit relais électronique 3.
