“…During the last decade, the cost of superconducting materials has been reduced by about 10% per annum [62] and it is hoped that this trend will continue. Furthermore -although the cost of a superconducting apparatus is still high in comparison with the cost of a conventional apparatus -a factor that has to be taken into account is that much lesser space is required to accommodate superconducting equipment [63,64].…”

In this paper, a short review is given on insulating materials at very low temperatures. Various insulating materials are investigated in terms of phenomena such as partial discharges. Some of the factors affecting the behavior of the insulating materials at very low temperatures, such as the quality of electrode surface, the stressed insulation volume and the existing bubbles, are also reported and commented upon. Proposals for future research are also discussed.

The resistive superconducting fault current limiter is well known for its simple structure and outstanding current-limiting effect, and it is broadly applied in power grid systems. The second-generation high-temperature superconductor (HTS) tape, of higher structural strength and greater room-temperature resistance, is well suited for application in resistive superconducting fault current limiters. The quenching caused by overcurrent in the HTS tape is a complexed coupling effect of several physical factors. The tape structure and properties directly impact the ultimate HTS tape’s quench performance. In this study, various SS316-laminated HTS tapes, of different critical currents, room-temperature resistances, and masses, were prepared. The pulse impact parameters of the various tape samples were measured using the RLC high-current impact test platform. By analyzing the resultant data, a quantitative assessment methodology to measure a tape’s tolerance toward impact was developed. The dependence of the HTS tape’s tolerance toward impact on its critical current, room-temperature resistance, and mass was studied. This provides numerical guidance on HTS material selection for resistive superconducting fault current limiters.

“…However, the smart grid meets important challenges associated with fault currents, which are occurring at rising rates, and have larger peak values and faster propagation speeds [8,9]. Therefore, in addition to intelligent parts for the realization of real-time monitoring and control of grid operation, smart grids feature advanced power applications such as fault current limiters to reduce the fault current rapidly and effectively [10,11]. A superconducting fault current limiter (SFCL) that mainly consists of high-temperaturesuperconducting (HTS) coils generates almost no Joule losses during normal operation; however, it can suppress fault currents much faster and more efficiently than conventional ones, let mechanical current breakers function, and recover to normal operation quickly when an electrical fault happens [12,13].…”

Investigations on Quench Recovery Characteristics of High-Temperature Superconducting Coated Conductors for Superconducting Fault Current Limiters

et al. 2021

Superconducting fault current limiters (SFCLs) are attracting increasing attention due to their potential for use in modern smart grids or micro grids. Thanks to the unique non-linear properties of high-temperature-superconducting (HTS) tapes, an SFCL is invisible to the grid with faster response compared to traditional fault current limiters. The quench recovery characteristic of an HTS tape is fundamental for the design of an SFCL. In this work, the quench recovery time of an HTS tape was measured for fault currents of different magnitudes and durations. A global heat transfer model was developed to describe the quench recovery characteristic and compared with experiments to validate its effectiveness. Based on the model, the influence of tape properties on the quench recovery time was discussed, and a safe margin for the impact energy was proposed.
