SF₆passive resonance DC circuit breaker combined with a superconducting fault current limiter

The Modeling of the LC Divergence Oscillation Circuit of a Superconducting DC Circuit Breaker Using PSCAD/EMTDC

“…It has no resistance in its superconducting state and, therefore, does not impede the flow of normal current. Additionally, the fault current is limited within about 2 ms through quenching when the critical point of the superconductor is exceeded by the fault current, thereby limiting the growth of the fault current [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. To respond quickly and safely to DC transients, we researched superconductor and mechanical DC cutoff technology and proposed a hybrid superconducting DC circuit breaker [19][20][21][22][23].…”
