An investigation on the harmonic attenuation effect of modern compact fluorescent lamps
Bibliographic record
Abstract
In recent years, awareness of energy conservation and environmental protection has promoted the use of energy efficient home appliances. Compact fluorescent lamps (CFLs) are expected to replace incandescent bulbs as they consume comparatively less energy and their useful life is longer. However, compact fluorescent lamps absorb extremely distorted current waveforms, resulting in high current harmonic injections on the electrical grid. Like other electronic devices based on single-phase rectification, CFLs are susceptible to the attenuation effect. If this effect is not taken into consideration, the cumulative harmonic current produced by the lamps can be significantly overestimated and the results obtained using the current-source model can be too conservative to be useful. This paper focuses on the harmonic characterization of modern compact fluorescent lamps. It presents experimental analysis investigation on the attenuation effect of CFLs, which is caused by the influence of distorted supply voltage on nonlinear load harmonic current injections.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
