Abstract
U ovom završnom radu opisan je princip održavanja transformatora uslijed raznih kvarova ili redovitih održavanja. Prvo je opisana dijagnostika energetskih transformatora s ciljem procjene pouzdanosti daljnjeg pogona. Zatim su opisani radovi održavanja transformatora te vremenski intervali izvršenja radova. U samu dijagnostiku spada nadzor energetskih transformatora u što se podrazumijeva učestalost ispitivanja transformatora, mjerenje otpora namota, rasipnog induktiviteta namota, otpora... More izolacije, kapaciteta i faktora dielektričnih gubitaka izolacije i provodnih izolatora, mjerenja struje magnetiziranja i omjera prijenosa niskim naponom, termovizijsko snimanje transformatora, mjerenje parcijalnih izbijanja ultrazvučnom metodom, ispitivanja ulja i ispitivanja stupnja polimerizacije papira. Nadalje u radove održavanja transformatora spadaju prvenstveno plan pregleda i provjera transformatora, te plan revizije i remonta transformatora. Kada smo definirali planove održavanja potrebno je definirane radnje provoditi. Na kraju su predstavljeni radovi održavanja za sustav disanja, provodne izolatore, primarnu zaštitu transformatora, ugrađene strujne mjerne transformatore, regulacijske sklopke i premještače, rashladni sustav, izolacijski sustav, aktivnosti koje zahtijevaju kotao i konzervator, stezni sustav namota i jezgra transformatora.

Abstract (english)
This final paper describes the principle of transformer maintenance due to various failures or regular maintenance. The diagnostics of power transformers is first described with the aim of assessing the reliability of further operation. Then, the transformer maintenance works are described, as well as the time intervals for the work performance. The diagnostics itself includes monitoring of power transformers, which includes frequency of transformer testing, measurement of winding... More resistance, winding inductance, insulation resistance, capacity and factors of dielectric losses of insulation and conductive insulators, measurement of magnetizing current and low voltage transmission ratio, thermal imaging of transformers, ultrasonic partial bursts, oil testing and paper polymerization degree testing. Furthermore, the transformer maintenance works primarily include the transformer inspection and inspection plan, and the transformer audit and overhaul plan. Once we have defined the maintenance plans, the defined actions need to be implemented. Finally, maintenance works for the breathing system, conductive insulators, primary protection of transformers, installed current measuring transformers, control switches and transducers, cooling system, insulation system, activities requiring boiler and conservator, clamping system and transformer core are presented.
