Abstract
The invention relates to an on-load tap-changer module (1, 15), in particular a power electronics on-load tap-changer module, for setting a transformation ratio of a power transformer (2) having at least one transformer winding that provides at least one tap (3), having: a control device (6), at least one tap changer (7) that can be switched on and off selectably by means of the control device (6) for setting the transformation ratio of the power transformer (2), and at least one clamping circuit (11) for limiting the voltage and set up, when a predetermined voltage threshold value is exceeded, to provide a predetermined current path to determine a predetermined transformation ratio of the power transformer. Furthermore, the invention relates to an arrangement composed of a power transformer (2) and an on-load tap-changer module (1, 15) and to a method for operating an on-load tap-changer module.
