Abstract
In this article, the aging and degradation of resin-rich mica-based insulation, used in Type II machine turn insulation, is studied to determine the characteristics of converters that affect insulation failure. Dissection of failed turn insulation specimens from voltage endurance tests and findings from simplified two-cavity specimens are studied at various stages of aging which are then related to the rise time, switching frequency, and overshoot of the converter supply. The experimental observations and the simulation studies show that the aging and life of turn insulation are found to be strongly associated with the discharge rate and the surface erosion of the insulation. The overlap and interface play a significant role in the failure of taped turn insulation.

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 it
