Impacts of operating conditions and line parameters on secondary arc extinction of single-phase autoreclosures

Single-phase autoreclosing is applied in transmission networks, if a single phase to ground fault occurs. One advantage of a single-phase autoreclosure is the fact that the energized conductors guarantee the synchronism of the system. Another advantage is that the power transfer of those conductors is not interrupted. The capacitive and inductive coupling between the energized conductors and the de-energized conductor feed a secondary arc during the dead time. Impacts of operating conditions and network conditions on arc extinction are analyzed in this work
