Title
(EN) CURRENT SENSING USING PANEL PLANE
(FR) DÉTECTION DE COURANT À L'AIDE D'UN PLAN DE PANNEAU
Abstract
(EN)
An apparatus for sensing current on a conductor of an electrical panel includes at least one sensing system, which comprises a ferromagnetic body and a sensor. The body can be formed of a ferromagnetic material, such as for example steel. The ferromagnetic body can have two legs, which when placed on a load-side of the electrical panel, is configured to form, together with a back plane of the electrical panel, a magnetic path around the conductor. The ferromagnetic body comprises at least two parts with a first air gap therebetween along the magnetic path. The sensor, which is arranged in the first air gap, is configured to measure a current or other electrical property representative of current on the conductor based on the magnetic field across the first air gap.

L'invention concerne un appareil de détection de courant sur un conducteur d'un panneau électrique comprenant au moins un système de détection, comprenant un corps ferromagnétique et un capteur. Le corps peut être constitué d'un matériau ferromagnétique, tel que par exemple de l'acier. Le corps ferromagnétique peut posséder deux pattes qui, lorsqu'elles sont placées sur un côté de charge du panneau électrique, sont conçues pour former, conjointement avec un plan arrière du panneau électrique, un trajet magnétique autour du conducteur. Le corps ferromagnétique comprend au moins deux parties présentant un premier entrefer entre ces dernières le long du trajet magnétique. Le capteur, qui est disposé dans le premier entrefer, est conçu pour mesurer un courant ou une autre propriété électrique représentative du courant sur le conducteur en fonction du champ magnétique à travers le premier entrefer.
