Research progress of YBCO superconductor in large-scale application

With some special electromagnetic properties different from the traditional conductors and magnetic materials, the superconductor has many potential applications in electrical engineering. Since the discovery of high Tc superconductor (HTS) in 1987, it has achieved significant progress in the application research of HTS in electrical engineering. BecauseYBCO superconductor shows better properties than BSCCO superconductor for electrical engineering application, recent application research of HTS for electrical engineering is focused on YBCO worldwide, and also achieved rapid progress. In this paper, we will review the recent research progress of YBCO superconductor in electrical engineering, commemorating the 30th anniversary of the discovery of YBCO superconductor.
