Abstract

fetched live from OpenAlex

In BC Hydro (Canada), fault recorders and system monitors have provided evidence of an increasing level of harmonics and revealed some cases of power system resonance. Also, there have been an increasing number of protective alarms, tripping of overloaded filters and unexpected high levels of harmonic currents in shunt capacitors, cables and lines. This paper describes BC Hydro's experience with one of the harmonic resonance problems in the Southern Vancouver Island power system.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
