Controllable reactor based hybrid HVDC breaker [PDF]
High Voltage, 2020 Short circuit fault occurrence in high‐voltage DC (HVDC) systems causes extremely high currents in a fast raising time that does not experience current zero‐crossing. To protect HVDC systems/grids against fault current, fast HVDC breaker is an essential equipment.

Research and experiment of a current-limiting HVDC circuit breaker
The Journal of Engineering, 2019 Existing mechanical HVDC circuit breakers (CB) are capable of interrupting HVDC currents within several tens of milliseconds, but this is too slow to satisfy the requirements of a reliable HVDC grid.
