“…Therefore, the timely extinction of the secondary arc caused by the single-phase ground fault is important for the success of single-phase reclosing. To ensure the safe operation of the power transmission lines and enhance the stability of the power system, a method that enables the self-extinction of the secondary arc is urgently needed to be found [1][2][3].…”

“…here, the subscripts e, p, and n indicate electrons and positive and negative ions, respectively; N is the density, in m −3 ; D is the diffusion coefficient, in m 2 /s; f is the net rate of the generation and loss processes, in m −3 s −1 ; and t represents time, in s. The main processes usually considered in Equations (1) and (3) are represented by their rates: Electron impact ionization, f ion = αN e µ e E; attachment of electrons to electronegative molecules (CO 2 , H 2 O, O 2 , etc.) present in air, f att = ηN e µ e E; detachment of electrons from negative ions, f det = k det N e N n ; electron-ion recombination, f ep = β ep N e N p ; recombination of positive and negative ions, f pn = β pn N p N n ; and natural background ionization, f 0 .…”
