Abstract :
Electric railways and mono-rails in Japan are operated by DC feeding systems. HSCB (high speed circuit breakers) are generally used for these electric installations. Recently, HSVCB (high speed vacuum circuit breakers) have been investigated. HSVCB makes current superimposed on fault current so that the current is forced to be zero and interrupts the current. HSVCB has an advantage such as small noise and environmental harmony. Therefore, an electric railway that adopts HSVCB has increased by the advancement of the vacuum technology in recent years. In this paper, we would like to clarity the basic performance of the HSVCB applied to the railway feeding systems
