Abstract

fetched live from OpenAlex

This paper presents a data correlation based idea and associated technique for determining the individual harmonic impact of multiple harmonic-producing loads scattered in a power system. The technique uses continuously recorded voltage and current data at each load point. The data are processed to determine the degree of association among the harmonic level at a measurement point and the behaviors of loads monitored. The results, degree of association, can be used to estimate the harmonic impact of each load. A real life case is used to illustrate the proposed technique. It is found that the technique can reveal the harmonic impact of the loads if the data points are selected judiciously.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
