Abstract: This specification relates to fault current limiter (FCL). More particularly, to solve problems of protecting and designing current limiting impedance in a protective coordination system, as limitations of the related art, the fault current limiter may measure heat capacity of a current limiting impedance unit by detecting fault current flowing to the current limiting impedance unit and limiting the fault current flowing to the current limiting impedance unit according to the measured heat capacity, which may result in preventing the current limiting impedance unit from being damaged due to the fault current, preventing an extended accident due to the damaged current limiting impedance unit and enabling a stabilized system and line protection.
