Experimental tests on a superconducting hybrid DC circuit breaker [PDF]

, 2016
Direct Current (DC) transmission systems are widely recognized offering significant potential for long distance high power delivery. DC circuit breakers are a key enabling technology for managing faults in multi-terminal DC networks (MTDC). However, DC current breaking is much more challenging than in AC systems because there is no natural zero ...
