Abstract :
The paper presents new results of experimental study of stability of the direct current electric arc in vacuum interrupter with an axially-symmetric magnetic field under contact opening. The study allowed to obtain more detailed data, on the dynamics of plasma glow and spots on electrodes during transition from stable to unstable stage of vacuum arc evolution. Features of stable and unstable stages of vacuum arc burning at direct current 50 - 150 A and at change of magnetic field from 100 up to 150 mT are investigated.
