[Our past: magnetic fusion]   [Our primary sponsor]   [Enabling Technologies]   [HTS applications status]

Enabling Technologies for HTS Grid Applications

  • Conductor
    • For cables: need high critical current with sufficient stabilization
    • For transformers, motors, generators: need acceptable critical currents in background fields from about 0.2 T ac to several Tesla dc.
    • For all applications, need sufficient mechanical strength (compressive, tensile, fatigue) for cool-down cycles, transients loads, centrifugal loads for generators/motors, etc.
    • For cables, transformers and FCLs need acceptable ac losses
    • Need to find a way to accommodate cable faults and coil quenching
  • Cryogenics
    • Efficiency at the operating temperature, reliability, cost
  • Cryogenic Dielectrics
    • Hold off operating and transient voltages for lifetime of device
    • Reliability
