Abstract
The security of high-impedance fault (HIF) relays is examined. Waveforms of HIFs as well as loads that behave to appear like HIFs were collected and processed. The detection parameters used in a number of present HIF detection algorithms were extracted and compared to test the algorithms' ability to discriminate between faults and fault-like loads. It was found that there are loads that imitate HIFs, and that the present algorithms lack the security required under these load conditions. The high-impedance fault-like loads considered were: an arc welding machine; a personal computer; and a fluorescent light. It was found that arc welders can easily imitate HIF conditions, and that the tested algorithms showed insecurity when tested with an arc welder load.< <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 it
