Interruption limits of mechanical circuit breakers and circuit upgrades for current injection in HVDC circuit breakers [PDF]
High Voltage, 2020 Current injection circuit breakers consist of a mechanical interrupter (MI) with a current injection and an energy dissipation branch in parallel. The performance of the complete device is largely determined by mechanical operation time and interruption performance of the MI.

Systematic Approach to HVDC Circuit Breaker Sizing [PDF]
IEEE Transactions on Power Delivery, 2020 High-voltage direct current (HVDC) grids can be protected by HVDC circuit breakers (DCCB) to selectively clear DC side faults and assure continuous operation of the healthy parts in the grid. Line inductors in series with DCCBs are essential to reduce the rate of rise of the fault current and to slow down the voltage decline in the healthy parts of the
