Analysis of a passive superconducting fault current limiter

IEEE Transactions on Appiled Superconductivity, 1998
An analysis was carried out to predict the forced response of the equivalent circuit of an innovative superconducting fault current limiter (FCL). The FCL employs two superconducting coils with differing critical currents wound noninductively. The analysis shows that to reduce the voltage drop under normal operating conditions, the coupling coefficient

Computer modelling of superconductive fault current limiters

Materials Science and Engineering: B, 1998
Abstract Investigations are being carried out on the use of superconductors for fault current limiting applications. A number of computer programs are being developed to predict the behavior of different ‘resistive’ fault current limiter designs under a variety of fault conditions.

Superconducting fault current limiter for railway transport

Physics of Atomic Nuclei, 2015
A resistive switching superconducting fault current limiter (SFCL) for DC networks with voltage of 3.5 kV and nominal current of 2 kA is developed. The SFCL consists of two series-connected units: block of superconducting modules and high-speed vacuum breaker with total disconnection time not more than 8 ms.

Superconducting fault current limiter with bulk materials

Physica C: Superconductivity, 2002
Abstract Superconducting materials offer the unique possibility to limit fault currents by their self-triggering quench to a resistive state above a given threshold current. Their use in power networks would improve the power quality, which is a real need today. YBCO or BSCO bulk materials are good candidates for current limitation.

Development of Superconducting AC Fault Current Limiter

1990
The authors have developed a new superconducting fault current limiter whose impedance during normal operation is very small. During fault conditions, the limiter behaves as a superconducting reactor. The limiter consist of a superconducting limiting coil and a superconducting trigger coil.

25 kV Superconducting Fault Current Limiter

1990
Our technological progress in die field of superconductivity over the last ten years made possible the manufacture of industrial lengths of conductors, consisting of NbTi ultra-fine filaments, embedded in a Cu-30 wt % Ni matrix; 50 Hz losses are greatly reduced, and the electrical resistance beyond the critical current is very large.
