Test Circuits for HVDC Circuit Breakers
IEEE Transactions on Power Delivery, 2017High 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, 1933The 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.

Interruption of fault current with delayed current zeros (DCZ) is one of the peculiarities of generator circuit-breaker (GCB) that differentiates it from other medium-voltage and high-voltage circuit-breakers. This paper aims to provide a guideline for precise calculation of short-circuit current requirements for GCB.
