From April 2007, DAPAS (Development of the Advanced Power system by Applied Superconductivity technologies), which is a 10‐year‐long program, entered the final phase with 4 years. For the last 7 years, the significant achievement of DAPAS is that a 10 m long and 100 A critical current‐coated conductor and core technologies of distribution line voltage class HTS power systems including cables, transformers, fault current limiters (FCLs), and motors have been developed. In particular, a 100 m length HTS power cable was installed and is operating well in the Gochang power system test center. Two different types of FCL were successfully developed and demonstrated very good results of fault current test with 22.9 kV distribution line voltage class. In the case of the HTS motor, it was well operated too on connecting to 2 units of a 1.1 MVA conventional induction motor each as a load. In addition, the coated conductor project team achieved a 30 m length and 185 A critical current‐coated conductor tape after 6 months since the hardware was set up.
