Effects of low air pressure on ac and dc arc propagation on ice surface
Bibliographic record
Abstract
The effects of air pressure on the AC and DC arc process on an ice surface, including velocity, parameters and flashover voltage, were studied. The results obtained showed that air pressure has an obvious influence on the arc propagation velocity, arc constant A, electrode voltage drop V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">e</sub> and consequently on the flashover voltage of the ice surface, V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">f</sub> . This decrease in V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">f</sub> is explained by the decrease in the E-I arc characteristics and arc propagation velocity, and by the relatively higher density of Na atoms in the arcs at pressures below standard air pressure. Based on these results, the mechanism underlying the decrease in the flashover voltage of ice-covered insulators at high altitude was analyzed

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.
