Abstract
The safe and reliable operation of high voltage(HV)switchgear directly influences the reliability of the whole substation's power supply, so the partial discharge detection of HV switchgear is particularly important. This paper mainly analyzes the principle of transient earth voltage(TEV) and ultrasonic wave methods of partial discharge detection of HV switchgear, and the advantages and disadvantages of these two methods. Four typical models of partial discharge, namely needle plate discharge, internal discharge, suspended discharge and surface discharge, are designed; and an experimental platform of partial discharge detection based on the combination of TEV and ultrasonic wave is designed. Through simulation experiments, the combination of TEV and ultrasonic wave methods is used to locate the orientation of the partial discharge source. This method is verified to be more accurate and practical for partial discharge detection.

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
