Significant environmental advantages

HTS Cable: Multiplying Grid Capacity

• User Benefits:– Higher Power Capacity - 3-5 x Conventional– Smaller right of way - easier siting/retrofits– Avoided construction - cost savings– Lower voltage - substation elimination– More environmentally acceptable - no oil

Power Cable Retrofit• Higher power density, lower

cooling requirement, oil free

• Retrofit of 400' (~120 m) of three–3-phase copper underground cables with a single 3-phase HTS underground cable

• Carries the same 2.4 kA total current at 24 kV (100 MVA) as the original copper cables and leaves 2/3 of conduit space available for future capacity

• Located within the Frisbie Substation of Detroit Edison, Detroit, MI

FCL: Benefits

• Compatible with existing protection devices

• Maximum allowable current adjustable

• Greater system flexibility - higher power

• Defer transmission/distribution upgrades

• Increased power reliability/quality

• Protects utility/customer equipment

• Uninterruptible power supply to gridLOS ALAMOS

FCL: Achievements

• Under construction: 17 kV, 45 kA, 765 MVA– Three phases– Handles 2 faults of 400 msec each, 15 s apart– Fault reduction of 80%– Tested 2000 A normal and 9000 A fault– Insulation Breakdown 110 kV– Cryocooler operation
