Process and Modeling of Arc on a Snow-Covered Insulator
Bibliographic record
Abstract
Snow and ice accumulation on high voltage equipment such as insulators and conductors may cause problems of mechanical and electrical origins. One of the most serious problems under snow and ice accumulation is insulator flashover, which has been studied to some extent by researchers in several cold climate countries. In this paper, the AC flashover process and electrical behavior of snow deposited on a polymer insulator is the subject of study. Moreover, a mathematical model for simulating the behavior of snow under alternating voltage is presented. For this, two experimental setups were developed and from the voltage-current characteristics of snow, which were measured from several different tests, it was found that the voltage across snow and the leakage current flowing through the snow-covered insulator are almost in the same phase, which it means that a snow-covered insulator behaves as a pure resistance. The resistance of snow is not linear, as it decreases as voltage increases. An increase in length of the snow cover results in an increasing in flashover voltage, but increasing the density and conductivity of water melted from snow yields the inverse effect and causes a sharp decrease in flashover voltage

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.
