Abstract (en)
[origin: WO2019120882A1] The invention relates to a transformer core with at least one additional leg. Said additional leg is used to form a leakage path. In order to optimize the installation space and for easier connection of the transformer windings, the transformer legs and the additional leakage path legs are not arranged along a common line.
