A Multiorifice Interrupter for High-Voltage Oil Circuit Breakers
Transactions of the American Institute of Electrical Engineers, 1943High-voltage oil circuit breakers for high-speed operation generally use some form of multibreak contact arrangement. These breakers perform satisfactorily but lack the simplicity of the conventional slower-speed two-break construction. The development of an unusually effective multi-orifice oil-flow interrupting unit now makes it possible to reduce ...

High-voltage oil circuit breakers for rapid reclosing duty
Electrical Engineering, 1944Experience has shown that high-speed reclosing of circuit breakers on high-voltage transmission lines is of considerable value in maintaining system stability and continuity of service. This paper describes a new line of outdoor oil circuit breakers and the special design features which make them suitable for 20- and 35-cycle reclosing duty at voltages

IEEE Transactions on Power Apparatus and Systems, 1964
A compound circuit is described for development and acceptance testing of circuit-breaker modules and circuit breakers up to 50,000 equivalent 3-phase module mva (megavoltamperes). The paper discusses high-current-source voltage requirements, synchronization of high-voltage-source application with final current zero, and high-voltage-source impedance ...

Insulative condition monitoring of high voltage circuit breaker
2010 5th IEEE Conference on Industrial Electronics and Applications, 2010In order to improve power system reliability, high voltage circuit breaker(HVCB) as an important power equipment, the insulation state must be monitored reliably. In the paper, a design approach for real-time data acquisition and remote transmission system base on field programmable gate arrays(FPGA) and ARM technology is presented. The approach adopts

Chromatic Assessment of High-Voltage Circuit Breaker Gases
2020Switching electric currents in high-voltage circuits involves mechanically separating two contacts to form an electric arc plasma which is then quenched. This operation is conducted in a tank containing a vacuum or one type of gas which has good arc-quenching properties.

Recent evolution of high-voltage SF6 circuit-breakers
IEE Colloquium on Physics of Power Interruption, 1995For a long time, SF/sub 6/ puffer circuit-breakers have been considered the most efficient and reliable type of interrupting switchgear. This technique was introduced by GEC ALSTHOM T&D (then DELLE ALSTHOM) at the end of the 1950s for medium voltage applications, and then extended in the 1960s to high-voltage circuit breakers. Since then, and until the
