In connection with executive management circles. the one essential Have leakage current can have certain Problems with the display of line currents occur. In such cases it can be useful a Vormagneti on all cores in the arrangement

counteract in the core in question. Further bias windings for the cores in each row are connected in series, and this series connection is between terminals VII-VIII. If a pre-magnetization stream χοή is fed in such a size that it is the same At./aiii of aniperc convolutions like the maximal Causes the voltage in the display winding to have the value zero at a conduction current which is equal to the maximum Kricchsiront, while it has a value with a certain polarity for a line current which is greater than the maximum Is Kiiechslromes, and it has a value of opposite polarity for a conduction current that is less than the maximum value of the Kiiechslromes. Heim checking the voltage induced in the display winding is between positive or negative signals instead of between large or small amplitude of the signals to distinguish, which is easier and allows a larger percentage line current.

exposed that the curve V ₁ - f (/ _w ) according to F i g. 2 is the same for both cores, e.g. B. KIl and / 711. However, it can happen that the nuclei ctsvas have other magnetic properties, such as from Fig. 3 can be seen. If the cores are influenced by the resulting currents I _n , of the same magnitude, then a certain, not insignificant voltage is nevertheless induced in the common display winding, this voltage being borrowed the amplitude and polarity from the difference 1 / between the curves in FIG. 3 depends. at an unfavorable combination of the cores in the pair, the display voltage becomes the same polarity like those who have to be displayed for the line

ao is achieved that the display signa !, which by dissimilar nuclei is caused to always have the opposite polarity compared to the display signal due to the line current to be displayed.
