절연변압기의 권선비 변화에 따른 초전도 한류기의 동작특성 연구

This paper analyzes the current limiting characteristics of the flux-lock type SFCL that has the structure including the superconducting element that is separated isolated- transformer, through short-circuit simulator. It measured operational characteristics of the flux-lock type SFCL according to change the secondary winding ratio of an isolated transformer. From the experimental results, we found that the flux-lock type SFCL with an isolate transformer was confirmed to be more effective for the fault current limiting and the recovery characteristics effect.
