Benefits of Controlled Switching of Medium Voltage Circuit Breakers

This paper describes the benefits of using controlled switching technology on medium voltage circuit breakers. Although this technology has been used on high voltage networks for over 30 years, recent technological advances have permitted the development of a new generation of controlled switching devices for medium voltage. This paper reviews controlled switching device approaches, describes m...

Arc Motion and Gas Flow in Current Limiting Circuit Breakers Operating With a Low Contact Switching Velocity

Arc motion in low voltage (240 VAC) high current (10–10 A.) current limiting-circuit breakers is dominated by arc root mobility. The mobility is influenced by the gas flow and gas composition in the contact region, but there is little experimental data on these effects. New pressure and spectral data measurement during arc movement are presented using a flexible test apparatus and an arc imagin...

Solid-State Circuit Breakers For Medium Voltage

How can the large power needs of future electric ships for propulsion, radar, and weapons systems be met given the prohibitive size and weight of the required number of standard 60 Hz AC generators and transformers? A solution may lie in a rugged, efficient, and compact solid-state, 10-20 kV Medium Voltage DC (MVDC) circuit breaker (Figure 1). In this paper, Diversified Technologies, Inc. will ...

Thermally Tripped Mems Circuit Breakers

 The use of MEMS electrical switches as miniature electrically resettable circuit breakers is described. A prototype based on nickel thermal actuators on silicon has been fabricated and tested, and the performance is compared to analytical models. Trip currents of ≈ 300 mA are obtained, with trip times less than 50 ms. Temperature dependence of trip current is shown to be below 0.2%/K. The rel...
