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 ...

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.

Superconducting fault current limiters
IEE Colloquium on High Tc Superconducting Materials as `Magnets', 1995Fault current limiters (FCLs), superconducting or otherwise, have the potential to reduce fault levels on electricity power networks, and may ultimately lead to lower rated components (i.e. cheaper) being used, or to increased capacity on existing systems.

A superconducting fault-current limiter
Journal of Applied Physics, 1978A conceptual design is presented for a fault-current limiter for the electrical power utilities which utilizes a superconducting element to commutate the fault current into a shunt resistor. The technical feasibility of the concept is supported by a computer simulation of the switching.

Cognition on the current-limiting effect of saturated-core superconducting fault current limiter
2015 IEEE Magnetics Conference (INTERMAG), 2015The saturated-core superconducting fault current limiter (SCSFCL) is an important facility for limiting the short-circuit fault current of the power grid. However, the cognition or the judgment on the current-limiting effect, which is the key indicator of the SCSFCL, is not unique.

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 ...

Electromagnetic fault current limiter
Electric Power Systems Research, 1997Abstract Due Due to electrical power system expansion, utility systems are faced with fault currents higher than the momentary and interrupting capabilities of the equipment installed. One method to solve the problem is to use a fault current limiter.

Current limiting level-time characteristic of a superconducting fault current limiter
Cryogenics, 1995Abstract 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.
