Abstract
The global surge in green-insulating liquid adoption by manufacturers and utilities is driven by the escalating demand for sustainable and environmentally friendly energy sources. Natural esters stand out as a green insulating liquid, an alternative to mineral insulating oil. However, natural esters encounter pour point challenges, particularly in cold regions. This research aims to enhance the performance of natural ester-insulating liquids, contributing to the evolution of sustainable energy technologies. In this study, optimization of pour point depressants’ impact on crucial oil properties like dielectric loss, viscosity, and acidity is investigated. Viscoplex 10-171 and Viscoplex 10-312 depressants were optimized using Taguchi methodology aided by grey relation analysis. Experimentation involved five levels 0.6 wt.%, 0.7 wt.%, 0.8 wt.%, 0.9 wt.%, and 1 wt.%, structured within an L25 orthogonal array to determine the most effective concentration. The optimization findings suggest that incorporating the two depressants does not exert notable effects on the oil properties, with all experimental values aligning within the specified ASTM standard.

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
