Light and tree inception characteristics of XLPE at elevated temperatures
Bibliographic record
Abstract
The authors describe the characteristics of light emission at an XLPE a (cross-linked polyethylene)-semicon interface held above and below the temperature at which the crystallites of the polymer start to melt. The spectra of EL (electroluminescence) and the light inception voltage of degassed, an N/sub 2/- and SF/sub 6/-impregnated XLPE are reported. It is shown that XLPE subjected to elevated temperature emits luminescence even without voltage application. This light is attributed to TL (thermoluminescence) which depends on the concentration of the crosslinking by-products present in the polymer. The TL spectra are only in the visible range. On the other hand, the XLPE-semicon interface held above room temperature and subjected to high electric stress emits EL, and the spectra of this light are in the visible and the UV ranges. Although the intensity of EL emitted at high temperature is lower than that emitted at room temperature, the UV light can photodegrade the polymeric insulation, which can lead to electrical tree inception.>

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.
