Swiss-based ABB Inc. feels the development of a new DC breaker for high-voltage transmission will help shape the energy grid of the future. Nikola Tesla (Westinghouse) and Thomas Edison (GE) battled ...
The rapid expansion of high voltage direct current (HVDC) grids, driven by the massive integration of renewable energy sources, has underscored the critical role of DC circuit breakers (DCCBs) and ...
A line of dc miniature molded-case circuit breakers is rated to 125 V (1 pole) and 250 V (2 to 4 poles) at up to 63 A for uses that include transit, communications, battery, and UPS applications. The ...
A team of researchers at the Department of Energy's Oak Ridge National Laboratory has developed more robust circuit breakers that are compatible with direct current (DC), paving the way for lower ...
One characteristic of adding PV solar to homes is a massive increase in high-voltage and high-current DC installations. With this comes a need for suitable breakers, but without the requisite ...
Direct current (DC) powers flashlights, smartphones, and electric cars, but major power users depend on alternating current (AC), which cycles on and off 60 times per second. That’s because AC is ...
Georgia Tech is to develop circuit breakers for >1MW dc power links up to 100kV – with wind farms, electric aircraft and electric ships in mind. Direct current power transmission is more efficient ...
