Abstract
Dissolved-gas analysis (DGA) was used to evaluate acceptable and dangerous gas levels in transformers, taking the equipment type (generation or transmission transformers) into account. The results are based on 6046 gas-in-oil analyses performed on Hydro-Quebec transformers over a period of 20 years and incorporated in a central computer data bank. The transformers are high-voltage conservator-type power transformers without on-load tap changers communicating with the main tank. The probability of failure in service as a function of the dissolved-gas concentration increases rapidly above a given gas concentration level to an extent considered unacceptable or dangerous in service. It appears that the acceptable levels of H/sub 2/, C/sub 2/H/sub 4/, and CH/sub 4/ are lower and those of C/sub 2/H/sub 2/ higher for the generation transformers than for the transmission transformers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
