Abstract (en)

[origin: WO0133308A1] The invention relates to a method for regulating the electrical voltage in electrical supply networks and/or consumer units and a device for carrying out said method. A regulating transformer (3) is inserted between a network node (1) in the supply network and/or the consumer unit and at least one end user (2). The regulating transformer (3) comprises a high leakage impedance, which limits the ring current to the order of magnitude of the nominal current, in the case of a short-circuit between adjacent tappings (5) of the partial windings. The regulating transformer further comprises a transfer switch (7), to switch the partial windings (4).
