Title
(EN) MEASUREMENT OF SUPPLY CURRENT
(FR) MESURE D'UN COURANT D'ALIMENTATION
Abstract
(EN)
A current sensor for the measurement of a supply current in a prime conductor comprises a helical winding of turns of insulated wire and a flexible support which flexibly supports the helical wire winding along substantially the whole of the length of that winding, the flexible support comprising an elongate strip of soft magnetic material such as a matrix medium in which particles of low magnetic impedance material are embedded.
(FR)
Capteur d'intensité servant à la mesure d'un courant d'alimentation dans un conducteur primaire, constitué d'un enroulement hélicoïdal de boucles de fil isolé et d'un support flexible qui soutient de façon souple l'enroulement de fil hélicoïdal, sensiblement sur toute la longueur de cet enroulement, le support flexible étant constitué d'une bande allongée d'un matériau magnétisable temporairement, comme par exemple un support de matrice, dans lequel sont incrustées des particules de faible impédance magnétique.
