Luminescence in polymeric insulation and its implication on insulation aging
Bibliographic record
Abstract
This paper describes the characteristics of three types of light emission that can occur from polymeric insulation subjected to uniform and divergent electric fields and/or high temperature. 1. Electroluminescence (EL), which is the light emitted at points of electric stress enhancement in the polymer occurs much before partial discharges (PD). EL can occur at cryogenic temperatures and at and above room temperatures. 2. Light emission which occurs from the surface of the polymeric insulation due to electron bombardment at high electric stress in high vacuum. 3. Thermoluminescence (TL), i.e. emission of light at elevated temperatures (>50/spl deg/C) caused by the presence of crosslinking byproducts in cable insulation. No electric stress is required for TL emission. The implications of light emission on polymer degradation and additives that have been successfully used to retard degradation are described.

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.
