In most highly developed electrical power system, there are several difficulties related from generation to distribution. Usually, power generation is located at remote area from the load center. Long transmission and distribution lines have to be constructed and maintained to meet required reliability, power quality and economic point of views. Reliable, cheap, efficient conductor is required ...

Abstract High-temperature superconductors (HTS) can be superconducting in liquid nitrogen (77 K) at atmospheric pressure, which holds immense promises for our future such as nuclear fusion, compact medical devices and efficient power applications. In a system, high short-circuit currents exceed the operational current by more than ten times, putting many parts of system risk. Superconducting fa...

In this paper, an application of superconducting fault current limiter (SFCL) is proposed to limit the fault current that occurs in power system, SFCL is a device that uses superconductors to instantaneously limit or reduce unanticipated electrical surges that may occur on utility distribution and transmission networks. Due to the difficulty in power network reinforcement and the interconnectio...

Superconducting fault current limiters (SFCLs) can be used to limit currents in both meshed DC and AC grids by transitioning from superconducting resistive state, the presence of high currents. While device is theoretically a great way protect grids, inherent inhomogeneity critical along superconductor length lead localized heating, called hotspots, ultimately destruction SFCL device. At EPFL u...
