Abstract
Field experiences have shown that transmission systems using voltage sourced converters (VSCs) with IGBT's can produce high frequency harmonic resonances in the VSC station environment. Modern cable terminations using non-geometric stress grading can be susceptible to degradation under these harmonics. In this study a setup was designed to test cable terminations under conditions representative of high frequency harmonic resonance in the field. Six different designs were experimentally analyzed for temperature increase under power frequency, high frequency, and combined voltage conditions. Further, analysis was carried out by circulating current, to test the additional effect of heating from load current. Results show a wide variation in local temperature gradients among termination designs. These differences can be attributed to variations in termination stress grading methods.

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
