Abstract

L'invention concerne le contrôle de la consommation de plusieurs appareils électriques fonctionnant dans les mêmes conditions d'alimentation et de charge. Pour contrôler automatiquement la consommation d'un certain nombre d'appareils électriques 10 branchés en parallèle à une source d'énergie électrique 11, chaque appareil 10 est associé à un circuit comprenant un générateur d'impulsions 12, un transformateur de courant 13 et un intégrateur 14. Les signaux de sortie des intégrateurs, représentant la consommation de l'appareil associé, sont appliqués à un comparateur/enregistreur 27. Application au contrôle du fonctionnement de moteurs électriques.The invention relates to the control of the consumption of several electrical devices operating under the same supply and load conditions. To automatically control the consumption of a certain number of electrical devices 10 connected in parallel to a source of electrical energy 11, each device 10 is associated with a circuit comprising a pulse generator 12, a current transformer 13 and a integrator 14. The output signals of the integrators, representing the consumption of the associated device, are applied to a comparator / recorder 27. Application to the control of the operation of electric motors.
