SMES is being applied on a microscale (1--10 MJ sorted energy) to improve electrical power quality. A major portion of the SMES refrigeration load is for cooling the conventional copper, vapor-cooled current leads that transfer energy between the magnet and the power-conditioning equipment. The lead refrigeration load can be reduced significantly by the use of high-temperature superconductors (HTSs). An HTS current load suitable for micro-SMES application has been designed. The lower stage of the lead employs HTSs. A transition between the lower stage and the conventional upper-stage lead is heat-intercepted by a cryocooler. Details of the design are presented. Construction and operating experiences are discussed.
