    • A voltage regulator includes a tap changer coupled to a voltage source terminal and a voltage load terminal. The voltage regulator also includes a first switch and a first current transformer coupled in series between the voltage load terminal and a first movable contact of the tap changer. The voltage regulator further includes a second switch and a second transformer coupled in series between the voltage load terminal and a second movable contact of the tap changer. A first silicon controlled rectifier and a second silicon controlled rectifier are controlled by a first control circuit and a second control circuit, respectively. The first control circuit and the second control circuit each include a rectifier, a gating switch, and a positive voltage detector.

    • 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.
