Influence of Temperature on the Surface Discharge Behaviour at Varying Altitudes for Aeronautical Applications
Bibliographic record
Abstract
In an aircraft the electrical wiring and interconnect systems are exposed to low pressures ($\geq 1 \text{kV}$) than conventional 115 V or 230 V, which means an intensified electrical stress across the insulation of the interconnect systems. The combined impact of high temperature, high voltage, and low pressure on the surface discharge of solid insulators is entirely a new challenge to the aviation industry. This study examines the influence of temperature by measuring the partial discharge inception voltage (PDIV) and flashover voltage (FOV) at various flying altitudes. Two electrode configurations generating homogeneous and inhomogeneous electric fields respectively were used to test polyether ether-ketone (PEEK) dielectric plates. The results have shown a considerable decline in the flashover voltage at the tested high temperature for homogeneous field condition. Under inhomogeneous electric field condition, the temperature influenced the flashover voltage at high air pressures ($>500$mbar), but the results converged to that of room temperature at relatively low air pressure.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
