Dual-circuit hybrid circuit breaker
2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017A DC fault will propagate quickly in a DC grid and results in significant DC voltage drop and large current increase. To protect the DC grid from the DC faults, the concept of hybrid HVDC circuit breaker (DCCB) is widely-accepted due to its low conducting loss and fast operation speed.

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.

The 150-kv. system operated for some years by the Southern California Edison Company has not made use of automatic operation of circuit breakers. The multiplication of generating stations and connections which accompanied the change to 220-kv. makes desirable the automatic sectionalizing of the line in cases of trouble and, therefore, requires circuit ...

CIRCUIT breaker application is being simplified. A subcommittee of the protective devices committee of the AIEE has studied methods of calculating short circuit currents and has prepared a report which presents a simplified procedure based on standardized contact parting times and typical current decrements.1 To facilitate the use of this method ...

Current can be transferred to the load of an inductive energy storage device by rapidly increasing the inductance of a circuit element connected in parallel with the load. The present paper suggests using a coil with a ferromagnetic core for this purpose. In addition to the principal (toroidal) field, an orthogonal (poloidal) control field is generated

The vacuum circuit breaker has fascinated the switchgear designer for many years, primarily because of the great advantages of vacuum interrupters, which are: (a) They are entirely self contained, need no supplies of gases or liquids and emit no flame or gas.
