Investigation on shed icicle characteristics and induced surface discharges along a suspension insulator string during ice accretion
Bibliographic record
Abstract
This investigation focuses on the dynamic process of ice accretion and induced surface discharges along a suspension insulator string in relation with the icicle characteristics in icing conditions. Using a high‐speed camera to record the insulator performance, the growth parameters of icicles at different shed edges were calculated and the characteristics of surface discharges were analysed with regards to the lapse time of ice accretion. It was found that the electric field strength can be quickly enhanced to the threshold value of air breakdown strength at the initial stage of ice accumulation, resulting in weak and unstable discharges at the air gaps between the icicles and the insulator shed surface. As the icicle kept elongating toward ice bridging, the discharges became stronger and more stable. The obtained results will be helpful to improve the operating safety of suspension insulators of power networks subjected to icing.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
