Abstract
Zadaća strujnih transformatora za zaštitu jest da mjerena sekundarna struja vjerno prati porast primarne struje znatno iznad nazivne vrijednosti. Ponašanje strujnih transformatora u tranzijentnim prilikama od neophodne je važnosti za brzo i pouzdano djelovanje relejne zaštite. Jezgre klase P, PR, PX i PXR služe kako bi prenijele informaciju o nastanku kvara, ali nisu primarno namijenjene da prenesu točnu informaciju o kvaru tj. valni oblik kvara. No, ovaj rad pokazuje da, ovisno o nazivnim parametrima jezgre i nazivnim parametrima struje kratkog spoja, one mogu biti primjenjive za prikaz tranzijentnog odziva.
Abstract (english)
The task of protective current transformers is to accurately represent the increase of the primary current well above the nominal value on the secondary terminals. Current transformer behavior in transient settings is of immense importance for fast and reliable relay protection operation. Core classes P, PR, PX and PXR are meant to convey fault occurrence information, but are primarily not meant to convey the exact fault current waveform. This thesis shows that, depending on the nominal core parameters and the nominal short-circuit current parameters, those core classes can be used to display transient response.
