Abstract

Prilikom rada energetskog transformatora mogući su brojni kvarovi i smetnje koji mogu oštetiti transformator i onemogućiti normalan rad elektroenergetskog sustava. Različite vrste zaštita projektirane su s ciljem pravovremenog detektiranja takvih pojava i štićenja transformatora od istih. Suvremeni sustavi zaštite oslanjaju se na tehnologiju numeričkih releja, koji objedinjuju brojne zaštitne i mjerne funkcije u jedan centralizirani uređaj, uz mogućnost podešavanja parametara zaštite od strane korisnika.

Abstract (english)

While operating, a power transformer can suffer a wide range of electrical faults and disturbances, potentially damaging the transformer, and disrupting the power supply system. Various protection types have been designed in order to detect such occurrences in a timely manner, and protect the power transformer. Modern day protection systems rely on the numerical relay technology, which enables the integration of multiple protection and measuring functions in a single centralized apparatus, which also enables the users to set all of the desired protection parameters.
