Abstract

fetched live from OpenAlex

Prebreakdown current versus voltage characteristics have been recorded for di-iso-octyl phthalate transformer fluid using the ramp voltage application technique. The object was to compare the results with similar data obtained from dimethyl siloxane and Voltesso 35 dielectric fluids. The characteristics of the ester oil were similar to those of the silicone oil and transformer oil, insofar as they obeyed the equation I varies as V/sup s/. The value of s for ester oil is a constant through all the experimental conditions and has the value 1.040+or-0.035. For transformer oil and silicone oil, s is changed when the maximum applied voltage and gap separation are varied. The response current for the ester oil is about two orders of magnitude stronger than that for the other two oils. Plotting the current vs. voltage in log-log scale, there is no threshold point for ester oil. The current on this scale increased very close to linearly with the ramped applied voltage. The direction of progression around the current vs. voltage loop reverses compared to that of silicone oil, which only happens at very high stress in transformer oil.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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.
