Claim 3:
4. The device according to claim 1, which further comprises:
a single-phase configuration of the device and two symmetrical current paths;
said at least one main winding of said at least one active part being disposed in each current path and having a high-voltage end connected to said phase connection and a low-voltage end connected to a step winding;
each component of said impedance units having two impedance windings coupled inductively to one another; and
one of said impedance windings being connected to said selector and said load changeover switch of a first step winding and another impedance winding being connected to said selector and said load changeover switch of a second step winding and interconnected, causing reactances of said impedance windings of a component to compensate for one another in an event of a symmetrical current flow through both current paths, and said respective component to have a low impedance value.
