Development of superconducting power equipments is closely related to that of superconducting wires. Recently, continuing from the first generation (1G) BSCCO wire, commercialization of the second generation (2G) wire, coated conductor (CC), is near at hand. SuperPower Inc., has already commercialized 2G wire of 600 m piece length. With the development of CC, superconducting power equipments are actively developed and some research groups reported successful demonstration results of the power devices such as cable, fault current limiter, and so on. Since critical current of commercialized coated conductor (CC) of 1.2 mm width is about 250 A at 77 K, methods like stacking or parallel connection that increase operating current are needed. This paper describes fabrication of large current limiting coil and presents electrical test results. The limiting coil was fabricated by assembling 2 modules in parallel; each module was wound by stacking 4 CC wires on a non-inductive pancake bobbin.
