This paper deals with analysis of the operational characteristics of a resistive non-inductive winding type based superconducting fault current limiter (SFCL) by using YBa2Cu3Oy (YBCO) coated conductor (CC), and its characteristics are analysed through experiments. A non-inductive winding type SFCL system has non-inductive solenoid type coils wound with the YBCO CC and each coil has four windings of the CC in opposite direction to cancel off each inductance, connected in parallel each other. In the experiment, a resistive SFCL was developed and the short circuit test was performed during 0.1 s. The load was pure resistance and the fault switch was closed when a fault occurs. In order to measure the current, shunt resistance was used. A hall sensor was installed in the center of the SFCL to investigate the non-inductivity. The experimental results are given with the theoretical predictions by using finite difference method (FDM). This analysis is expected to be used in the electrical circuit application as well as the SFCL.
