Abstract (en)
[origin: WO2015144541A2] The invention relates to a method for permanent, contactless measuring of current strengths on a single conductor or multi-conductor sheating (6), wherein a) a collar is created around the sheathing (6) such that the collar encloses the sheathing (6) together with the interior conductors (7) thereof, and a plurality of magnetic field sensors (8) are arranged and aligned in said collar, distributed around the circumference thereof, b) the magnetic fields generated due to the current flowing in the enclosed, insulated conductors (7) are measured by the magnetic field sensors (8) and detected as electronic data, c) the effective flowing current strengths in the individual, sheathed conductors are calculated by means of previously, empirically determined algorithms for mathematical description of the relation between current strengths in individual conductors of a conductor bundle and the magnetic fields generated thereby, d) the determined current strengths are forwarded to a server as a data basis for the management of current distribution networks. The device for carrying out the method includes a fastenable collar in which a plurality of magnetic field sensors (8) is arranged over the circumference therof.
