摘要

A switching arrangement (15) for an electric system (10) that includes a first and a second tapped winding (11, 13) comprises: - a first on-load tap changer (16) that includes a first discharge terminal (161) and three first switching terminals (162), at least two of which can be connected to associated first taps (12) of the first tapped winding (11); - a second on-load tap changer (17) that includes a first discharge terminal (171) and three second switching terminals (172), at least two of which can be connected to associated second taps (14) of the second tapped winding (13); - the second discharge terminal (171) is connected to the first discharge terminal (161) or to a first switching terminal (162") that is not associated with a first tap (12).
