Hybrid superconducting magnetic device

A hybrid superconductive device for stabilizing an electric grid, comprising:

• a. a magnetic core arrangement at least partially carrying AC windings;
• said AC windings connectable to an AC circuit for a current to be limited in the event of a fault;
• b. at least one superconductive coil configured for storing electromagnetic energy;
• said at least one superconductive coil magnetically coupled with said core arrangement and at least partially saturating said magnetic core arrangement during use;
• wherein said hybrid superconductive device further comprises a switch unit which switches electric current patterns corresponding to the following modes:
• at least partially charging said superconductive coil;
• a standby mode when said superconductive coil is looped back;
• and at least partially discharging said superconductive coil into said circuit;
• wherein said magnetic core arrangement comprises at least two plate-shaped core members;
• said superconductive coil is disposed between said two plate-shaped core members;
• core members carrying AC windings interconnect said two plate-shaped core members and circumferentially distributed thereover.
