Abstract

A hybrid fault current limiter and active noise cancellation system is being developed at the Colorado School of Mines for use in high voltage DC power systems with very high SNR requirements. This system uses a resistive superconducting fault current limiter (FCL) and electrically isolated solenoid to produce a variable resistance across a length of bulk high T_c superconducting YBCO filament. This paper describes the process of material testing of the YBCO filaments, modeling and modulator prototype development. Results from the material testing and modeling are also presented
