Abstract
A series voltage compensator for three-phase unbalanced sources is presented and analyzed. The system, based on a three-phase voltage source inverter connected in series to the supply through a three-phase delta-wye power transformer, proves to be feasible and performs as expected. A 1.3 kVA prototype was built and tested with 10.75% of unbalance and 9.01% of magnitude error ( mod MF mod =0.909). The results showed a very good correlation with the expected performance, producing a balanced line-to-line load voltage with a low harmonic content (average THD=20%), without filter. The compensator required only 168.8 VA, which shows one of the main advantages of the compensator scheme proposed.< <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
