Franck, Christian, Prof. Dr. | ETH Zurich first HVDC grids are in operation and more grids are planned. To fully utilize the advantages of a grid, fast and reliable circuit breaker technology is needed. One technology that fulfills these requirements is the Hybrid HVDC Circuit Breaker. The key component of such a breaker is an Ultra Fast (mechanical) Disconnector (UFD).
