Abstract (en)

[origin: WO03044611A2] The invention relates to a method and device for regulation of the electrical voltage in electrical mains networks and/or user plants with a regulating transformer. Said regulating transformer (3) is inserted in the path of the energy flux between at least one generator (1) and at least one end user (2) with a switch (7) for switching the partial windings (4) of the regulating transformer (3). The regulating transformer (3) further comprises a high leakage impedance which limits the circulating current to the order of magnitude of the nominal current in the case of a short circuit in adjacent tappings (5) of the partial windings (4). The regulating transformer (3) is embodied as a single winding transformer, for example an autotransformer or as a multiple winding transformer, for example, a full transformer.
