Test Circuits for HVDC Circuit Breakers

IEEE Transactions on Power Delivery, 2017
High voltage direct current circuit breakers (HVDC CBs) are necessary for reliable and safe operation of future multi-terminal meshed HVDC grids. So far no commercially mature products of such equipment exist. A few industrial concepts as a result of advances in power electronics have been proposed and prototypes have been built.

Circuit Breaker Protection for Industrial Circuits

Transactions of the American Institute of Electrical Engineers, 1933
The demand for continuity of service to customers, together with the need to reduce maintenance costs, and increase the safety to operators and property, has made it necessary to improve the protective devices used in the distribution circuit. In the past, this protection has been provided by knife switches and fuses.
