Abstract
Ovaj rad se bavi specifičnom problematikom naponskih transformatora velike snage s otvorenom jezgrom. Korištenjem suvremenih metoda i njihovom eksperimentalnom verifikacijom ideja je nadograditi postojeći dizajn naponskih transformatora velike snage, točnije ugraditi dodatni sklop za potrebe zadovoljavanja klasa točnosti prema IEC 61869 ili IEEE C57.13. standardu. Kako bi se navedeno moglo ostvariti, nužno je ustanoviti s kojim elementima se može utjecati na naponsku i kutnu pogrešku. U radu je opisana primjena sklopa za korekciju kutne pogreške, koji je izveden pomoću međutransformatora i zračne prigušnice. Uspješnost pristupa popraćena je proračunom u programskom paketu Mentor Graphics MagNet te verifikacijom tijekom laboratorijskih ispitivanja na stvarnom naponskom transformatoru velike snage. Pritom se analizira i određuje utjecaj raznih parametara koji su relevantni za navedeno korekcijsko rješenje, kako bi se dobio temeljit pregled predložene tematike.
Abstract (english)
This paper deals with the specific issue of power voltage transformers with open core. Using modern methods and their experimental verification, the idea is to upgrade the existing design of the power voltage transformer, more precisely the integration of a aditional device in order to meet the accuracy classes according to IEC 61869 or IEEE C57.13. 3 standard. In order to achieve this, it is necessary to establish which parameters influence the voltage and angular error. This thesis describes the usage of the device for the angular error correction, that is derived of an current transformer and air inductance. Efficiency of the approach is followed by the calculation in the software package Mentor Graphics MagNet and verification of the methods by laboratory tests on a real power voltage transformer. In doing so, the impact of various parameters that are relevant to the above correction solutions is analyzed and determined, in order to obtain a thorough overview of the proposed topic.
