Abstract

fetched live from OpenAlex

U ovoj doktorskoj disertaciji prikazana je koncepcija, realizacija i potvrda nove metode jednovremenog etaloniranja strujnih mernih transformatora sa dve različite merne aparature. Pregledom stručne literature ne postoji podatak da je ova metoda ranije primenjivana. U disertaciji su prikazane različite merne metode za ispitivanje i etaloniranje mernih transformatora koje imaju primenu u savremenoj praksi i koje podrazumevaju i različite merne mogućnosti. Takođe je i ekperimentalno potvrđeno jednovremeno ispitivanje i etaloniranje strujnih mernih transformatora sa nekoliko mernih aparatura koje su zasnovane na različitim metodama. Sprovedna istraživanja i eksperimentalni rezultati pokazuju i potvrđuju niz prednosti ovakvog načina etaloniranja. Detaljna analiza komponenti merne nesigurnosti pokazala je da se primenom ove metode postiže poboljšanje merne nesigurnost etaloniranja za skoro red veličine u odnosu na klasično pojedinačno etaloniranje sa dve različite merne aparature. Analiza uticajnih veličina na mernu nesigurnost pokazuje da se po ovoj novoj metodi etaloniranja eliminiše niz komponenti od kojih su najznačajnije: uticaj nejednakosti referentnih struja i ispitnog opterećenja. Istraživanja su takođe pokazala da jednovremena metoda osim što doprinosi podizanju tačnosti etaloniranja strujnih transformatora, ima primenu i u etaloniranju mernih aparatura za ispitivanje tačnosti mernih transformatora i interkonparaciji strujnih etalon transformatora. Kroz konkretne primere realizovane u praksi, razmotreni su i prikazani načini etaloniranja mernih aparatura za ispitivanje tačnosti ovom novom metodom. Interkomparacijom dva merna sistema visoke klase tačnosti Nacionalnog merološkog instituta Kanade (National Research Council Canada), od kojih je jedna razvijena u Elektrotehničkom Institutu "Nikola Tesla", pokazana je i prednost primene jednovremene metode u oblasti primarne metrologije strujnih mernih transformatora.

Full frame distilled prediction

Teacher imitation

Not 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.
