Space Plasma Distribution Effect of Short-Circuit Arc on Generation of Secondary Arc [PDF]
Energies, 2018 Secondary arc is more severe in the ultra-high voltage (UHV) power grid. However, the mechanism for the generation process of secondary arc at the extinction moment of a short-circuit arc is not yet clear.

Modeling Study of the Secondary Arc With Stochastic Initial Positions Caused by the Primary Arc [PDF]
IEEE Transactions on Plasma Science, 2015 In the conversion process from primary arc to secondary arc, there exists stochasticness phenomenon of the initial positions of secondary arc. However, the present simulation results of the arcing time with the arc chain model are constant, which is not consistent with the test results.
