Effect of pressure and temperature on interfacial breakdown between two dielectric surfaces
Bibliographic record
Abstract
Breakdown experiments were performed on slices of EPDM rubber pressed one against the other. To achieve this, an experimental jig was designed so as to induce breakdown between the two slices, longitudinally along their interface. Effects of interfacial pressure and of the presence of silicone grease at the interface are taken into account. Breakdown voltages are given for AC measurements. The authors illustrate how deformations, due to high-temperature operation, can occur in a cable joint. A relationship is also established between this deformation and the joint interfacial pressure, which in turns affects the interfacial dielectric strength. It is concluded that the dielectric strength of an EPDM/EPDM interface is greatly affected by the interfacial pressure. Moreover, the presence of silicone grease both improves (at low pressure) and limits, even if the interfacial pressure is increased (above 50 kPa), the dielectric strength of EPDM/EPDM interfaces.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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.
