The characteristics of the vacuum arc and the interruption ability on the high-speed vacuum circuit breaker

A high-speed vacuum circuit breaker, which forced a fault current to zero, has been investigated. The characteristics of the arc behavior and the interruption ability were investigated experimentally. Two types of electrode, an axial magnetic field electrode and a disk-shaped electrode, were tested. The results demonstrate the characteristics of the arc behavior and the interruption ability of the high-speed vacuum circuit breaker.
