Analysis on Current Limiting and Recovery Characteristics of a SFCL Dependent on Magnetic Coupling of Shunt Reactors

션트리액터의 자기결합유무에 따른 초전도전류제한기의 전류제한 및 회복특성 분석

The current limiting and recovery characteristics of a superconducting fault current limiter (SFCL) using shunt reactors were analyzed. Generally, the shunt reactor has a role to distribute the even voltage drop between high-Tc superconducting (HTSC) elements comprising the SFCL. However, the shunt reactors magnetically separated was not contributed to the equal voltage distribution between the HTSC elements. Through the experiments for the SFCL with both the magnetically coupled and magnetically uncoupled shunt reactors, the magnetically coupled shunt reactors were confirmed to improve the current limiting and recovery characteristics of the SFCL.
