Abstract
Dissolved Gas Analysis (DGA) has now become a standard in the utility industry throughout the world and is considered to be the most important oil test for oil-filled power transformers. This article intends to show that the gassing of oil is a more complex phenomenon. Aged oil and reclaimed aged oil samples were submitted thermal and electrical stresses (considering various scenarios) and the dissolved gasses analyzed by chromatography. This contribution provides experimental evidence that the chemical composition of hydrocarbon blend and the oil born decay products are also contributing factors to oil gassing. The influence of oil born decay products onto the diagnostics predicted by some DGA techniques is also emphasized. Although such a research is still in a preliminary stage, some very stimulating results have been obtained.

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
