Abstract
A current transformer arrangement which is provided on the secondary side with an integration stage provided with a secondary coil represented by two astatically designed parallel-connected coils lying side by side 31, 32. The outer magnetic stray field has no effect under practical conditions on transmission of a measured value. A high output signal on the secondary side is obtained by strong magnetic coupling between the primary line and secondary coil by using a ferromagnetic material. Primary line 23 is preferably a flat conductor with appropriately positioned slot-like openings 25-28 so that the primary lines 29a-29g are formed by changes in line cross section (Figures 5, 6, 7). <IMAGE>
