Abstract

Magistarski rad obrađuje iskustveni pristup u održavanju energetskih transformatora gdje se dijagnostičkim metodama i postupcima održavanja nastoji ocijeniti njihovo stanje. Energetski transformatori stare tijekom pogona, što rezultira smanjenjem pogonske pouzdanosti kako transformatora tako i postrojenja. Dijagnostikom energetskog transformatora može se predvidjeti vrijeme kada je potrebno poduzeti bitne aktivnosti održavanja (npr. generalni remont) kojim se izbjegava neočekivani i neplanirani zastoj te mu se produljuje životni vijek uz povećanje njegove pouzdanosti u radu. Sve je potkrijepljeno izmjerenim veličinama na konkretnom primjeru, a to je energetski transformator u vlasništvu Hrvatske elektroprivrede.

Abstract (english)

This master thesis addresses empirical approach to maintenance of power transformers involving diagnostic methods and maintenance procedures to assess their condition. Power transformers life is impaired during their operations the consequence of which is lower operational reliability of both transformers and the system as a whole. The diagnostic tests performed on a power transformer could predict the time required to take necessary steps and execute certain maintenance works (e.g. overhaul) that would prevent unexpected and unscheduled failure or outage. This would extend the operational life of the transformer and increase its reliability.
