Anotace
An electric arc burning in mercury vapours exposed to external magnetic field changes its discharge path into a helix according to the Thomson principle of energy minimization. The voltage between the adjacent turns of the helix curvature may result in the critical electric field strenght in the vicinity of the arc channel, that leads to the branching and formation of a new discharge path acting as a turn-to-turn short. We have been interested in the electric field profile and surrounding parameters at the moment of branching, the speed of a new channel warming, temporal evolution of the restoration of a regular spiral channel, development of the arc current and distribution of the voltage between the series resistor and arc channel during the breakdown.
