Abstract

1. A screening element, consisting of a plurality of insulant layers (9, 12, 13, 14) and a conductive paper insert (10), for yokes (4) of stepwise laminated iron cores, of transformers and inductance coils, for screening the stepped edges of the yoke from end faces, or end screening rings, of windings, characterised in - that the conductive paper insert (10) is completely metallically separated from all neighbouring components (2, 4) which carry opposite voltages, - that the conductive layer (11) in the conductive paper insert (10) is of high resistance and free from voltage-balancing conductors, - that the electrical potential carried by the conductive insert (10) is adjusted in a purely capacitive manner by the relation of the distance from the yoke (4) to the conductive paper insert (10), to the distance from the conductive paper insert (10) to the end face or end screening ring of the winding (2), and - that the edges of the conductive paper insert (10) are set back on all sides with respect to the edges of the remaining insulant layers (9, 12, 13, 14).
