The computer analysis of the virtual current chopping in the vacuum circuit breaker.

진공차단기의 가상전류 촙핑에 대한 컴퓨터 해석

The work is concerned with the analysis of the voltage escalation caused by the repeated restriking and extinguishing of the current when the vacuum circuit breaker interrupts the arc furnace load current. The paper particularly concentrates on the protective measures that may be adopted to overcome the restriking problem and guidelines are evaluated.
