Abstract
Since a few years, non-destructive techniques for assessment of power transformer insulation systems have been developed. The dielectric response in time and frequency domain is studied to determine the oil/paper insulation condition. One of the important parameters affecting the dielectric response is the temperature. On real transformer, the temperature of measurement is not controlled and is usually related to ambient temperature, therefore in order to compare measurements at different temperature it is important to study the influence of this parameter. It is well know that the temperature dependency to the response of transformer insulation follows an Arrhenius type law and that it is possible to normalize to a master curve measurement taken at different temperature. To evaluate this dependency and to model it, this study was done on transformer model with both the dielectric response in time and frequency domain with the temperature varying from 10 to 50 degC. The results allow us to model the dependency of the temperature and to calculate the activation energy.

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
