The PROMISE is composed of a superconducting transformer, a superconducting fault current limiter and superconducting power cable of length 5 m. Three superconducting apparatus are enclosed all together in a long scale cryostat to be kept at the liquid helium temperature of 4.2 K. The major insulation is provided by liquid helium. The PROMISE withstands AC voltage of 6 kV for 2 minutes with quite low partial discharge. A voltage-current synthetic test has proved that the PROMISE has a transmission capability of 6,000 V-1,000 kVA. The fault current limiter actually limits overcurrent and prevents the other apparatuses from quenching. Quench current level coordination is actually realized in the PROMISE.}, pages = {945--948}, title = {Development of the Prospective Power Transmission Model System Integrated under Superconducting Environment-PROMISE}, volume = {5}, year = {1995} }
