Abstract
In a current-limiting device, a plurality of current-limiting elements are connected in series to one another, and are inserted between the system power source of an electric power system and the load thereof. In the device, transformers, the number of which is equal to that of the current-limiting element S through Sn, are arranged. The primary windings of the transformers are connected to the current-limiting elements in the same polarity, respectively, and all the secondary wings thereof are connected in parallel to one another.
