Towards the superconducting fault current limiter
IEEE Transactions on Power Delivery, 1991The advent of low-loss AC superconductor wires opens the way to a new current limiting technique: that of extremely fast transition from a superconducting state to a resistive state when the fault current exceeds the conductor's critical current. A 25 kV single-phase prototype is described which consists of a Nb Ti superconducting coil without iron ...

Hybrid superconducting-magnetic fault current limiter
Digest of Technical Papers. PPC-2003. 14th IEEE International Pulsed Power Conference (IEEE Cat. No.03CH37472), 2004This limiter is intended to protect high-speed electronic circuits from subnanosecond duration high voltage transients. It operates at liquid nitrogen temperature and could be used in cryogenic electronic systems based on high-T/sub c/ superconducting devices.

Superconducting Fault Current Limiter optimized design
Physica C: Superconductivity and its Applications, 2015Abstract The SuperConducting Fault Current Limiter (SCFCL) appears as one of the most promising SC applications for the electrical grids. Despite its advantages and many successful field experiences the market of SCFCL has difficulties to take off even if the first orders for permanent operation in grids are taken.

Current Limiting Characteristics of Transformer Type Superconducting Fault Current Limiter
IEEE Transactions on Appiled Superconductivity, 2005The transformer type superconducting fault current limiter is composed of a series transformer and a superconducting current limiting device. The primary winding of the transformer is connected in series to the power transmission line, and the secondary winding is short-circuited through the superconducting current limiting device whose normal ...

Superconducting fault current limiters (SFCLs) are used to limit the short-circuit current level in electrical transmission and distribution networks. Applications of SFCLs would not only decrease the stress on network devices, but also can offer a connection to improve the reliability of power system.

IEEE Transactions on Applied Superconductivity, 2018
This paper proposes the concept of “fault current limitation coordination” in a future electric power grid with multiple superconducting fault current limiters (SFCL). Not only the fault current limitation of each SFCL on a transmission line, but also the transient stability of the grid with SFCLs should be taken into account, because the disturbance ...

Realization study of superconducting fault current limiter
2011 1st International Conference on Electric Power Equipment - Switching Technology, 2011The 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), 2016The 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.

25 kV Superconducting Fault Current Limiter
1990Our 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.

High temperature superconducting fault current limiter development
IEEE Transactions on Appiled Superconductivity, 1997A near term high-temperature superconductor (HTS) application is the fault current limiter (FCL). This paper describes the development and testing of a 2.4 kV, 2.2 kA(RMS) fault current, 150 A(RMS) continuous current, HTS FCL that uses a Bi-2223 Ag-based conductor.
