Influence of aging on prebreakdown characteristics of ester liquids with experimental and statistical analysis
Bibliographic record
Abstract
This study emphasizes the pre-breakdown phenomenon of low pour point synthetic esters with thermal degradation for potential usage in cold climatic regions. It is to be mentioned that two synthetic esters having a pour point less than -60°C are chosen for this work. The investigations are aimed at understanding the pre-breakdown behaviour of these very low pour point liquids at room temperature. The testing is performed using a point-plane electrode configuration under AC stress in a hermetically sealed test cell. To understand the influence of thermal degradation, the insulating liquids are subjected to a controlled thermal stressing under sealed conditions. The measurements are reported at different thermal aging duration (2 weeks, 4 weeks, and 6 weeks) at a tip of radius 5.46 μm and 10.75 μm with an inter-electrode distance of 10 mm. The measurements include partial discharge inception voltage, breakdown-streamer-inception voltage, and acidity of the liquids at different aging conditions. The influence of thermal degradation on the pre-breakdown characteristics of the fluids is reported. In addition, a two-way ANOVA (with interaction) statistical analysis has been performed on the experimental data.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
