Abstract

This paper describes arc forms and their transitions in vacuum in-terrupter with an axial magnetic field. The mechanism of transitions from the initial constricted arc to the diffuse one is proposed. By quoting series of experimental re-sults obtained by Westinghouse Science &. Technology Center USA

a formula of critical axial magnetic field is given.
