On the nature of growth of water trees and electrical aging of cross-linked polyethylene
Bibliographic record
Abstract
The nature of AC field aging of cross-linked polyethylene (XLPE) using NaCl and CuSO/sub 4/ (0.1 M) electrodes was studied with Fourier transform infrared absorption (FTIR), thermally stimulated discharge current (TSDC), and thermal transient current (TTC) measurements. FTIR measurements show that oxidation of stabilized XLPE is significantly lower than that of the unstabilized materials. No noticeable increase in bound water content in the polymer was observed as measured by IR absorbance at 3370 cm/sup -1/. Progressive enhancements of absorbance at approximately 1715 cm/sup -1/ and the TSDC peak at 70 degrees C with increasing field aging time appear to have the same origin. Thermal transient current magnitude is related to that of the integrated charge released in a TSDC thermogram.>

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.
