초록

We have investigated the quench behavior of the series connection of resistive type superconducting fault current limiter (SFCL) components based on YBCO films. Equal shunt resistors $R_s$ across individual SFCL components successfully produced simultaneous Quenches for 5 components in series, resulting in equal application of voltage to all components. If the two components having the highest and the lowest critical currents ($I_c$) quench safely, others quench altogether The highest shunt resistance is to guarantee the safe quenches of all components, leading to the equal voltage applications within the first half cycle after a fault in the short circuit test. The highest $R_s$ was found to be 28 ［$\Omega$］ for the components in the given quench environment. Considering the safe quenches and protection coordination, the optimal $R_s$ was suggested to be approximately a half of the highest $R_s$,, allowing wide selection of $R_s$ and $I_c$'s. This design provides a practical wav of connecting small SFCL components in series for high voltage application.
