A 6600 V / 210 V 100 kVA hybrid-type superconducting transformer has been developed. In this transformer, the low-voltage, high-current winding is made of liquid helium-cooled superconducting wire and the high-voltage winding is made of liquid nitrogen-cooled low-loss copper wire. The iron-core is placed in the environment of the room temperature outside the cryostat vessel. The cryostat vessel has a two-layer configuration of liquid helium- and liquid nitrogen-cooling vessels. Thus, the apparatus developed here is called as the hybrid-type superconducting transformer(H-SCT). In this paper, the concept, the design feature and measured characteristics are obtained through short-circuit and no-load tests. Its critical quencing current and inrush current are also included as measured characteristics.
