Sažetak
U ovom radu analiziran je uticaj pojave zasićenja strujnih transformatora, usled struja kvarova velikih vrednosti u sistemu, na talasni oblik struje na sekundaru strujnih transformatora, kao i analiza rada diferencijalne zaštite transformatora u takvim uslovima. Analize su vršene na softverskom modelu zaštitnog uređaja, a potom i na stvarnom uređaju injektiranjem odgovarajućih signala na njegove ulaze, primenom ispitnog kofera za ispitivanje zaštitnih uređaja. Potom je izvršena komparacija odziva softverskog modela i stvarnog uređaja. Modelovanje mreže i analize vršene su u softverskom paketu DlgSILENT PowerFactory, a ispitivanja zaštitnog uređaja su vršena pomoću DOBLE ispitnog kofera.
