Abstract
<div class="htmlview paragraph">This paper presents a summary of a Honeywell collaborative IR&amp;D project with University of Toronto on current arc fault detection and protection (AFDP) circuits and systems for the aerospace industry.</div> <div class="htmlview paragraph">Arc fault detection and protection pose a significant challenge for airlines, aircraft manufacturers, the military, and regulatory agencies such as the FAA. Most of the AFDP research and technology development efforts to date have concentrated on the detection of parallel arc faults because of the ease of differentiating them from other operating conditions due to their high energy levels and potential for serious damage. In contrast, series arc fault currents are limited by the electrical load and are thus more difficult to detect.</div> <div class="htmlview paragraph">The objectives of this paper are threefold: to provide additional new information on the characteristics of series arc faults; to provide a review and characterization of existing on-line methods of arc fault detection and protection; to summarize the critical challenges and opportunities for implementing on-line arc fault detection and protection for aerospace next generation electrical power systems including high voltage AC and variable frequency systems.</div>

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
