TESTING OF POWER TRANSFORMERS

U ovom završnom radu se obrađuje tematika ispitivanja energetskih transformatora te se opisuje princip rada transformatora i njegovih dijelova. Energetski transformator je ključni element elektroenergetske mreže koji omogućava tehnološki i ekonomski povoljnu proizvodnju, prijenos, distribuciju i potrošnju električne energije. Njegova uloga je ekonomičan, pouzdan, siguran prijenos i pretvorba električne energije. Naglasak u radu je stavljen na životni vijek transformatora, rutinska te specijalna ispitivanja koja se rade po narudžbi kupca, kako bi se ispitala ispravnost rada transformatora.In this final paper, the topic of testing power transformers is covered, and the principle of operation of the transformers and its parts is described. The power transformers are a key element of the power grid that enables technologically and economically favorable production, transmission, distribution, and consumption of electricity. Its role is economical, reliable, safe transmission and conversion of electricity. Emphasis in the work is placed on the lifetime of the transformer, routine and special tests that are done at the request of the customer, in order to test the correct operation of the transformers
