CAPTEUR DE COURANT INDUCTIF POUR APPAREIL ELECTRIQUE

摘要

The current to be measured (Ip) is carried by a single primary conductor (10) which is surrounded by a helicoidal winding (21) of a ferromagnetic material. The ends of the helicoidal winding terminate in parallel plates (24,25) which are positioned by an insulating spacer (27). The magnetic flux in the magnetic circuit and hence the primary current (Ip) may be detected by a Hall effect sensor or a further inductive winding
