- Abstract
- SFCL(superconducting Fault Current Limiter) which had zero impedance characteristic does not have power loss and limits quickly fault current. So it plays a rule as a protective equipment. And there are many type of SFCL. In this paper, we analyzed a SFCL with twice Quench so as to improve existing SFCL that operates regardless of scale of fault current. This SFCL with twice quench composed of extra series resistance(RS) and could limit once or twice dependent on scale of fault current. We analyzed operating characteristics and power burden of SFCL and its components according to fault position and series resistance(RS). Through the analysis, we could confirm that SFCL with RS operated at lower current, limited the fault current faster. And components’s power burden could be analyzed.
