Abstract :
The authors developed a DC S/N transition type three-phase fault current limiter, the primary element of which, is made of the superconducting bulk material, Bi-2223. This element is connected to secondary windings of transformers, through a modified half control bridge. This unique, single element device simultaneously limits and interrupts fault current, in three-phase power systems. This paper describes the results of tests, using a small scale model and simulation results
