An efficient deep learning based scheme for adaptive auto-reclosing in power transmission lines

Alexandria Engineering Journal
As a large percentage of faults in transmission lines are single-line-to-ground (SLG) and transient in nature, the use of adaptive single-phase auto-reclosing (ASPAR) schemes is essential.
