Current-limiting unit for an AC device, and use of the unit in a power transmission system
In order to reduce the energy losses, at least two saturable inductor devices (12, 13) are provided in the current-limiting unit for each phase of the AC device. Each inductor device has an AC winding (10A, 10B, 10C; 11A, 11B, 11C) and a superconductive DC premagnetising winding (20, 36) which satur...
