Many superconductor applications such as magnetic levitation train (MAGLEV), magnetic resonance imaging (MRI) and superconducting magnetic energy storage (SMES) must be operated on persistent current mode to eliminate loss. Research on PCS using coated conductor (CC) tape has not been actively in progress, compare with that using BSCCO tape. In this paper, current charging rate was adjusted to 0.5 A/s to investigate operating characteristics of PCS. To analyse current decay during persistent current mode, new electrical equivalent model considering the n-value of CC was applied. Experimental results were compared with the theoretical results which were derived by applying finite deference method (FDM). We concluded that the characteristics of initial current decay were determined by the voltage generated in the load due to n-value, joint resistance and current charging
