The KOSPI, which had been soaring, fell below the 3,900 mark due to concerns over the overvaluation of U.S.-origin artificial intelligence (AI). On the 5th, the Korea Exchange activated the sell-side ...

Abstract: It has become necessary to develop high-voltage dc (HVDC) circuit breakers to protect against fault currents that may occur in HVDC grids. One possible HVDC circuit breaker design uses ...

Abstract: In vacuum circuit breakers, the anodes often become active with the heating of high current constricted arc and generate secondary plasma, which has a negative impact on interruption. The ...

Electrical power transmission networks are protected and controlled by medium and high-voltage circuit breakers. Breakers are meant to make and break the flow of electrical currents in transmission ...
