Abstract:
1. A current measuring transducer for measuring the current flowing through an electrical cable, wherein the transducer comprises: a ring probe, a magnetoresistive sensor, and an evaluation device for calculating the values obtained by the magnetoresistive sensor, wherein the ring probe contains an annular core, wherein the ring probe is divided into a basic ring section and at least one movable ring section, wherein the movable ring section defines an open and closed state, and in the open state a radial cable insert opening is opened, and in the closed state of the movable ring section a closed arrangement is created in which the annular core surrounds the cable, wherein the ring probe with the basic ring section and the movable ring section defines a circular arrangement, wherein radial insertion of the cable extending axially to the current measuring transducer into the inside area of the ring probe pivots the movable ring section inwardly from one state to the other and, in the closed state, measurement of the current in the cable inserted into the inside area is made possible.
