FIELD: electricity.
SUBSTANCE: invention is referred to electric engineering and can be used for supplemental reactivity of an arc furnace transformer. Reactive ballast arrangement (V) for the arc furnace consists of a choke coil (1) with an open switch (2) for load increment changing which is suitable for installation of the choke coil (1) reactance under load. Reactive ballast arrangement (V) is connected before the transformer of the arc furnace (O) used, in particular, for steel making.
EFFECT: simplifying and improving accuracy of reactivity installation.
