ABSTRACT:
An inductive current measuring sensor is provided comprising several coils connected electrically in series and disposed in a polygonal contour, so as to surround the conductor on which it is desired to measure the current. Each coil comprises windings disposed on an insulating bobbin and connection elements. The bobbins are disposed on the face of a printed circuit having a central recess through which the conductor may pass. The printed circuit carries conducting tracks interconnecting the fixing points of the connection elements together and to external connection members.
