An economical and reliable DC circuit breaker for DC voltage > 3.5kV is not commercially available today. The lack of such a breaker has been inhibiting the development of DC power distribution in factories (especially processing plants with many variable speed motors); for microgrids (including on ships, oil platforms, and wind farms), and for multiterminal HVDC power transmission, as in the supergrid.
very little relationship to how the Ballistic Breaker works.

Meeting with China EPRI
C-EPRI is the research arm of China State Grid, focused on HVDC equipment. They are interested in using Ballistic Breakers for multi-terminal HVDC.
