Abstract
Problem koji se analizirao u ovom radu je utjecaj harmonijskih članova u struji uklopa kod uklapanja trofaznih transformatora. Navedeni su harmonijski članovi koji su važni za prepoznavanje nastanka pojave struje uklopa za ispravan rad zaštitnih releja. Predstavljeni su problemi koji se javljaju prilikom prepoznavanja nastanka struje uklopa kod modernih transformatora te kako se isti rješavaju. Objašnjeni su različiti tipovi zaštitnih releja trofaznog transformatora koji se koriste za zaštitu i prepoznavanje struje uklopa.

Parallel abstract (English)
Problem which is analyed in this paper is the influence of harmonic members in the inrush current of energization three-phase transformers. Here are mentioned harmonic which are important for recognizing the inrush current for the correct work of protection relay. Here are introduced problems which occurs during the recognition of forming inrush current on modern transformers how are they being solved. There are explained different types of protection relays of three-phase transformers which are used for protection and recognizing the inrush current
