Abstract
To protect a facility from momentary voltage drop, we are studying a short time SMES system. For this SMES, a helium free superconducting pulse coil using conduction cooling is developed. Also short time power converters and a high-speed voltage drop detector for a 1 MJ class SMES are designed. To confirm the design of components, a 100 kJ class demo coil and converters are constructed and tested
