| Popis: | A superconducting current limiter should secure the stability of a power system by making it durable. That is, even if a fault current is applied repeatedly to a superconductor, its characteristics should remain unchanged. The fault angle at the fault time within a power system varies depending on the failure position, cause, and type. Therefore, to investigate the durability of a superconducting current-limiting element, it is necessary to examine the quenching characteristics based on the fault angles. In this paper, a YBCO-coated conductor, whose current-limiting ability and stability had been proven in previous studies, was used to manufacture superconducting current-limiting elements and conduct a durability test. The durability test measured the quenching characteristics while a fault current was applied repeatedly at certain intervals depending on the fault angles. The superconducting wire used in the durability test was a YBCO-coated conductor with a stainless stabilization layer, which showed the best mechanical characteristics among the various thin-film-type wires. |
