Dynamics of arc phenomena at closure of electrical contacts in vacuum circuit breakers

Dynamic phenomena accompanying electrical contact closure in vacuum circuit breakers are considered as consecutive stages, including breakdown, touch, compression, restitution, bridging, and arcing at bouncing. The hybrid mathematical model is elaborated to describe dynamics of the arc and forces ac...
