Method and device for permanent current measurement in the cable distribution cabins of the 230 V / 400 V network level.

摘要

The inventive method is used for permanent, non-contact measurement of currents on a single-conductor or multi-conductor sheath (6) by a) a sleeve around the sheath (6) is applied so that they the sheath (6) with their in-lying conductors (7 b) the magnetic fields generated due to the current flowing in the enclosed insulated conductors (7) are measured by the magnetic field sensors and detected as electronic data, c) by means of empirically previously determined algorithms for the relation between the currents in the individual conductors (7) and the magnetic fields generated thereby effectively flowing currents in the individual conductors (7) are calculated as a data basis for the management of power distribution networks and forwarding to a server. An apparatus according to the invention for implementing the method includes a sleeve which can be fastened around a single-conductor or multi-conductor jacket (6), in which a plurality of magnetic field sensors distributed over its circumference are arranged.
