Inclined plane initial tracking voltage for AC, +DC and -DC
Bibliographic record
Abstract
The tracking voltage in the inclined plane test with AC is compared to the tracking voltage with DC, using the initial-tracking-voltage test method as per ASTM D2303 and a proposed coefficient of variation parameter. The severity of DC, as opposed to AC voltage, on RTV silicone rubber materials is confirmed using both strategies, where +DC is found to be the most severe voltage. The leakage current waveforms are found to consist of two components corresponding to wetting of the surface and to dry-band arcing. The mean value of the leakage current is a reflection of the wetting of the surface; whereas, the leakage current variation is a reflection of the dry-band arcing. Accordingly, a coefficient of variation parameter is proposed as an indicator of the relative severity of the dry band-arcing. Employing this coefficient of variation parameter, the ratios of the equivalent +DC and -DC to AC initial-tracking voltage are attained for 30 wt% silica filled two-part RTV silicone rubber. The results obtained using the coefficient of variation parameter have been verified experimentally using the initial-tracking-voltage in ASTM D2303.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
