Abstract

a. Compteur d'énergie électrique alternative comportant un transducteur de détection de courant par inductance mutuelle, destiné à détecter des valeurs très variables du courant. b. Compteur caractérisé par un transducteur d'intensité 12 à inductance mutuelle formé par un enroulement primaire pour recevoir directement la composante d'intensité de l'énergie électrique à mesurer, avec un secondaire 41 couplé par inductance sur le primaire et donner un signal analogique ei qui est proportionnel à la dérivée en fonction du temps de la composante d'intensité. c. L'invention s'applique aux compteurs d'énergie électrique pour des appartements, des maisons individuelles, des immeubles, etc.at. AC electrical energy meter comprising a mutual inductance current detection transducer intended to detect highly variable values of the current. b. Meter characterized by an intensity transducer 12 with mutual inductance formed by a primary winding to directly receive the intensity component of the electrical energy to be measured, with a secondary 41 coupled by inductance to the primary and give an analog signal ei which is proportional to the time derivative of the intensity component. vs. The invention is applicable to electric energy meters for apartments, single-family houses, buildings, etc.
