Current interrupting process in a vacuum circuit breakers ...· Vacuum interrupter arcs show two different modes of either diffuse or constricted arcs. The arc voltage of the diffuse arc is relatively low. In contrary, the constricted arc is characterized by a single bulk plasma column similar to an arc observed in gases carrying a large current. The boundary of the two arc modes depends on the current level, the contact gap, the shape, and material of the ...[email protected]
