Abstract

fetched live from OpenAlex

Esters dielectric fluids are found to be prominent replicate for mineral oil based insulation systems. Explicit studies on aging performance of these new insulating oils improve existing knowledge on the actual performance and degradation process. In this work, degradation of synthetic ester and natural ester has been investigated in comparison to mineral oil. Investigation is aimed at understanding the generation rate of soluble and colloidal particles in different oils with aging. Thermal aging is carried out as per ASTM D 1934 with a controlled aging history at different durations in presence of cellulose. Later, separation of colloidal particles is carried out as per ASTM D 1698 to study the comparative degradation rate of oils. Turbidity of oil and Particle counter measurements are performed before and after centrifuge to identify the growth of decay contents with aging in oils. A significant difference in the evolution of decay contents has been identified between esters fluids and mineral oils. The impact of colloidal particles on degradation of ester fluids is almost negligible whereas the degradation in mineral oils majorly governed by colloidal particles.

Teacher imitation

Not 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.
