PRILOG EKSPERIMENTALNOM ISTRAŽIVANJU FITOVANJA KALIBRACIONIH KRIVIH STRUJNIH MERNIH TRANSFORMATORA
Ključne reči:
fitovanje krive, kalibracija, klasa tačnosti
Sažetak
U radu se eksperimentalno istražuje problem fitovanja kalibracionih krivih strujnih mernih transformatora (SMT). Efikasan algoritam fitovanja omogućuje preciznu i tačnu elektronsku online korekciju grešaka SMT i time efektivno unapređenje njihove klase tačnosti. U radu se daju rezultati jednog takvog algoritma koji u 8 kalibracionih tačaka u opsegu 1% ‑ 200% nominalne primarne struje SMT koriguje grešku prenosnog odnosa do nivoa 0,004%.
