Abstract

U radu je napravljen pregled sustava motrenja energetskih transformatora. Objašnjen je princip rada sustava motrenja te je obrazložena svrha ugradnje uz procjenu isplativosti. Navedeni su glavni mehanizmi nastanka kvarova za ključne dijelove transformatora. Opisana je primjena sustava motrenja te je napravljen pregled veličina i dijelova transformatora koje je moguće motriti uz obrazloženje zašto je korisno motriti pojedinu veličinu i opis metode motrenja. Opisana je sklopovska i programska struktura sustava motrenja. Dan je kratki pregled sustava motrenja dvaju svjetskih proizvođača (Alstom i ABB) te je detaljno opisana struktura i funkcije sustava motrenja domaćeg proizvođača (Končar TMS).

Abstract (english)

This thesis gives a survey of power transformer monitoring. Working principle of the monitoring system and the purpose of installation with the evaluation of cost effectiveness are explained. The main fault mechanisms for transformer key parts are given. The application of monitoring system and an overview of monitored transformer parameters and parts are given along with the benefits that are provided by monitoring techniques. The hardware and software structure of the monitoring system is described. A brief overview of the monitoring system of the world's two manufacturers (Alstom and ABB) is given, whiles the monitoring system of the domestic producer (Končar TMS) is described in detail.
