Abstract
Galloping of transmission lines creates some cyclic stresses in the conductor and accreted atmospheric ice covering the conductor, which may result in ice failure leading to shedding. Attempts have been made in this research to estimate these cyclic stresses, and experimental tests have been conducted to study their effects on atmospheric ice. First, galloping of an ice-covered conductor was simulated by appropriate modification of existing models for bare conductors submitted to galloping. Then, the results of simulation were applied as input for a new model developed using ABAQUS. The results show that the layers of atmospheric ice at the top and bottom of the conductor endure maximum stress. The results of experimental tests with increasing cyclic stress show that ice does not break during galloping at wind velocities below 4.5 m/s. The tests under cyclic loads with a constant amplitude reveal that the ice does not fail under stresses corresponding to wind speeds of 3 and 4 m/s, and sometimes fails under stresses arising at a wind speed of 5 m/s.

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
