Abstract (en)

[origin: WO2015028253A1] In an on-load tap changer (10) for voltage regulation of a tap-changing transformer (15), provision is made for the tap-changing transformer (15) to have at least one phase (16) to be regulated which has a first winding (20) and a second winding (30); the first winding (20) has a tapped winding (21) comprising even-numbered winding taps (23) and a main winding (22), and the second winding (30) has a tapped winding (31) comprising odd-numbered winding taps (33) and a main winding (32); the first winding (20) and the second winding (30) are inductively coupled to the tapped windings (21, 31) having the even-numbered and the odd-numbered winding taps (23, 33); the on-load tap changer (10) has a selector (40) for alternately powerless preselection of the even-numbered or odd-numbered winding taps (23, 33) to be connected.
