Abstract
The flickermeter described in International Electrotechnical Commission (IEC) Standard 61000-4-15 is widely used to quantify the voltage flicker level in practical applications. The IEC flickermeter generally performs well for incandescent lamps. However, it fails to measure the flicker of non-incandescent lamps caused by some ranges of interharmonics. This paper suggests modifying the existing IEC flickermeter by adding a new block to it in order to enable accurate measurement of the flicker caused by high-frequency interharmonics. A digital implementation of the proposed modified flickermeter is tested, showing encouraging results. The error of the modified flickermeter is very low compared to the original one, even for the worst conditions. The changes implemented in the flickermeter do not affect its regular performance measuring incandescent lamp flicker due to amplitude modulation, making it a more generic flickermeter version. An arc furnace simulated by PSCAD/EMTDC is used to check the performance of this flickermeter.

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
