The Coreless Superconducting Fault Current Limiter 15 kV 140 A
Published by Michał MAJKA, Janusz KOZAK, Electrotechnical Institute Abstract. The superconducting fault current limiter (SFCL) is a device allowing for a more effective use of the existing power network infrastructure. The limitation of short-circuit currents by the SFCL to safe levels will result in the network elements being susceptible to smaller electrodynamic and thermal overloads.Continue reading “The Coreless Superconducting Fault Current Limiter 15 kV 140 A”
