Thermal Performance of Nomex-910 and TUK Insulating Papers in Soyabased Natural Ester Oil
Bibliographic record
Abstract
In this paper, evaluation of Nomex-910 and thermally upgraded Kraft (TUK) paper has been investigated in soya-based natural ester oil by performing accelerated thermal ageing.All the test samples have been prepared in standard oil/paper ratio in accordance with the IEEE Std.C57.154.2012 and are thermally stressed at 120 0 C, 150 0 C and 180 0 C as per modified ASTM D1934.Diagnostic measurements those including dielectric strength and tensile strength for insulating papers; UV/Vis spectroscopy, Dissipation factor, and Resistivity of oil have been reported as per ASTM standard test methods.The degree of concentration of conductive contaminants in Nomex system is slightly higher but are comparable.This is attributable to the high absorbance of Natural ester fluid.It is found, that dielectric strength and mechanical strength of Nomex paper is superior to that of the TUK paper.The deterioration rate of paper and the oil/paper insulation system has been verified with the natural ester-nomex insulation system and is found to be a possible alternative.

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.
