Abstract
This paper presents the results of using the low frequency harmonics of leakage current as a measure of dry band arcing in salt-fog. Sleeved high temperature vulcanized (HTV) silicone rubber rods were tested under 0.25, 0.40 and 0.60 kV/cm in salt-fog at two different salinities, i.e. 1000 and 2500 /spl mu/S/cm. The leakage current was measured and analyzed using fast Fourier transform (FFT). The results show that as the electric field increases, the fundamental component of the leakage current decreases and both the third and fifth harmonic components increase. Also, increasing the salinity of the fog increases both the third and fifth harmonic components with no significant change in the fundamental component. In general, harmonic components increased only when arcing occurred; thus providing a signature for the dry band arcing activities.

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 it
