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.

DURING the past few years the rapid expansion of mercury-arc rectifier installations at 600 volts d-c, both as to the total kilowatts installed and the relatively large number of units operated in parallel, has emphasized the importance of switchgear in providing suitable rectifier operation.

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.

2020 IEEE Electric Power and Energy Conference (EPEC), 2020
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.

The principle of operation of oil circuit breakers has been conceived to the present time as deionization of the arc stream during the time required for the recovery voltage to appear across the circuit breaker terminals. An alternative principle is here developed in which the arc products are swept away by the scavenging action of an oil blast.

Price dynamics with circuit breakers
Quantitative Finance, 2019We model the dynamics of an asset price in the presence of a circuit breaker. A circuit breaker is a trading halt imposed by the exchange after the price drops below (or rises above) a pre-specified value within a trading session. The investors' anticipation of the probability of a halt feedbacks on the price process. This leads to coupled integral

The Expulsion Oil Circuit Breaker
Transactions of the American Institute of Electrical Engineers, 1934In the expulsion type of oil circuit breaker the arc occurring on circuit interruption is ``expelled'' from the contact chamber by a high velocity gas blast. Breakers of this type have demonstrated their capability of consistently interrupting short circuits on a typical large electric power system within 1 or 2 cycles of arc.
