Sfcl Location Selection Considering Reliability Indices
, 2010 The fault current levels through the electric devices have a significant impact on failure probability. New fault current results in exceeding the rated capacity of circuit breaker and switching equipments and changes operation characteristic of overcurrent relay. In order to solve these problems, SFCL (Superconducting Fault Current Limiter) has rising

Experimental Tests of a Resistive SFCL Integrated With a Vacuum Interrupter [PDF]
IEEE Transactions on Applied Superconductivity, 2016 A resistive superconducting fault-current limiter (SFCL) has been developed using round magnesium diboride (MgB2) wire. The SFCL coil was wound using an interleaved coil arrangement to minimize the total coil inductance. The SFCL coil demonstrated reliable and repeatable current-limiting properties during testing.

Cryogenic DC Circuit Breaker Based on High‐Power Press‐Pack IGBT
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.This paper presents the performance of cryogenically compatible 3.3 kV/1.5 kA PP‐IGBTs as the main circuit breaker in a hybrid circuit breaker. The 3.3 kV/1.5 kA press‐pack IGBT can interrupt currents exceeding 5.1 kA when immersed in a liquid nitrogen bath. PP‐IGBTs are promising candidates for high‐power circuit breakers in cryogenically cooled power
