Title (EN) CURRENT SENSOR WITH MAGNETIC TOROID SINGLE FREQUENCY DETECTION SCHEME
(FR) DETECTEUR DE COURANT A PROCESSUS DE DETECTION A FREQUENCE UNIQUE ET TOROIDE MAGNETIQUE
Abstract:
(EN) A sensor device for sensing current in a primary source (AC or DC), including a conductor forming at least one winding on a magnetic material toroid and a secondary source of current. An output reader measures the instantaneous loading of the signal passing through the windings as a function of the primary current. A resistor measures the resulting instantaneous loading by demodulation to capture the resulting pulses, the polarity of the primary magnetic field being determined by the polarity of the resulting pulse aligned either at the rising or trailing slope of the applied signal.
(FR) L'invention porte sur un détecteur du courant d'une source primaire (c.a. ou c.c.) comprenant: un conducteur formant au moins une spire d'un toroïde de matériau magnétique, et une deuxième source de courant. Un lecteur de sortie mesure la charge instantanée du signal traversant l'enroulement en fonction du courant primaire. Une résistance mesure la charge instantanée résultante par démodulation pour capturer les impulsions résultantes, la polarité du champ magnétique primaire étant déterminée par la polarité de l'impulsion résultante alignée sur la pente ascendante ou la pente descendante du signal appliqué.
