“…Recovery voltage is considered to be the voltage across the arc gap after arc extinguishing. Work by Jacek [13] indicates that the recovery procedure of gaseous medium is consistent with the rising process of air withstand voltage V air , which is shown in (8).

“…In this paper, to model the secondary arc, the widely used Kizilcay model in recent studies [28][29][30][31] is employed. Since this model is based on thermal instability, it can perfectly replicate the behaviour of secondary arc, and this model is also suitable for low range arc current from 1 to 55 A.…”

Even though shunt compensation of transmission lines (TLs) is a common practice to limit the overvoltages stemming from the Ferranti effect, it may cause transient and steady‐state resonant overvoltages when one phase is left open due to the single‐pole‐open condition following the temporary phase‐to‐ground (Ph‐g) fault. Furthermore, the existing shunt reactors potentially increase the duration of the secondary arc current at the fault point and hence prevent offering fast single‐pole reclosing. To exploit the mentioned issues, in recent studies, a neutral reactor is introduced, which is installed in the neutral point of the shunt reactors; nonetheless, obtaining the appropriate amount of it is remarkably challenging. In this paper, an optimal neutral reactor (ONR) is determined based on an optimization problem, which minimizes the neutral reactor cost subject to limiting both resonant overvoltages and the duration of the secondary arc current. In modelling, the Laplace domain is employed rather than the phasor domain to consider both transient and steady‐state conditions since this technique allows having better control over transient overvoltages as well as transient secondary arc.

“…The steady-state analysis is a simple study and can provide an initial estimation of the secondary arc duration. However, in shunt compensated lines, it leads to a more pessimistic assessment of the situation [13]. This is due to the fact that the shunt reactor reduces the rate of rising of the recovery voltage on the open phase compared with a non-compensated line [4].…”

“…In this section, the ability of the proposed neutral reactor in successfully extinguishing the secondary arc is investigated based on the steady-state analysis. Compared to the time-domain simulations, the steady-state analysis is a more conservative criterion for checking the secondary arc extinction in shunt compensated TLs [13]. The time-domain simulation studies will be presented in Section 6.…”
