Current limiting level-time characteristic of a superconducting fault current limiter

Cryogenics, 1995
Abstract A model superconducting fault current limiter (SE-FCL) has been developed. The adopted superconducting cable is composed of six strands insulated from each other. The current limiting level of the SC-FCL is measured under two types of overcurrent, a sinusoidal and an inrush current.

Realization study of superconducting fault current limiter

2011 1st International Conference on Electric Power Equipment - Switching Technology, 2011
The fault current for large-scale power systems is higher than normal and interception using a current breaker can thus be difficult. To address this problem, power system reorganization and circuit breaker upgrades can be considered. However, existing systems could be operated by introducing a superconducting fault current limiter.

Basic concepts of superconducting fault current limiter

2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016
The need for power demand has been ever increasing due to numerous day-to-day causes. With increase in power demand, the fault levels witness a general rise. The superconducting fault current limiters have been seen as a much needed power device to limit the fault current in the electrical power system.

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.

Application of Superconducting Films to Fault Current Limiter

Japanese Journal of Applied Physics, 1994
The applicability of high-T c-superconducting films to a fault current limiter (FCL) without liquid nitrogen ( L-N2) was investigated. The FCL element consists of a 200-nm-thick YBa2Cu3O7- X (YBCO) film having a current-limiting area 4 mm wide and 90 mm long.

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.

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.
