Lightning overvoltage studies of Siahbishe 400 kV Gas Insulated Substation
Bibliographic record
Abstract
Lightning surge overvoltages are generally related to two cases, direct lightning stroke and back-flashovers. Lightning overvoltage waves travel on the transmission line and then enter a substation. High voltage equipment in a substation can be affected by transient overvoltage. This paper investigates the influences of lightning surge with fast front wave on Siahbishe 400 kV Gas Insulated Substation (GIS) located in the north of Iran. The fast transient overvoltages induced in major parts of GIS are investigated due to the first and subsequent direct lightning strokes and back-flashovers. We also show the relationship between the lightning surge current and the overvoltage induced at the entrance of the substation. In addition, the proper arc distance value for 400 kV transmission line string insulators is obtained.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
