115kV Superconducting Fault Current Limiter Model

Underwrite 115kV substation resistive superconducting fault current limiters (SFCLs) operating with zero electrical impedance during normal grid conditions, instantaneously quenching into a high resistance in 0.5 milliseconds during lightning/short-circuit faults (saving transformers from explosive destruction). Model utility equipment lease contracts ($3.5M/substation/yr), and 20-yr IRR.
