Abstract

A current detector comprising a first and a second current-path detector each in the form of a sheet-metal punching having a pair of relatively broad terminal webs of rectangular shape joined together via a bridge of arcuate shape. The bridges are slender compared to the terminal webs for concentrated current flow therethrough. Various arrangements are possible for the two current-path conductors, but their bridges are invariably placed in superposition upon one another. A Hall generator is positioned between the bridges so as to be acted upon by magnetic fields created upon current flow therethrough. One of the terminal webs of the first current-path conductor is electrically connected to one terminal web of the second, in such a way that the magnetic lines of force due to current flow through the two bridges act in the same direction upon the Hall generator.
