Abstract

Transformator je ključni element elektroenergetskog sustava za prijenos i
distribuciju električne energije te ga je potrebno konstantno nadzirati i štititi od
kvarova I nenormalnih pogonskih stanja.
U diplomskom radu navedeni su kvarovi i smetnje koje mogu nastati tijekom
pogona transformatora, te nadzor potrebnih veličina pomoću kojih se otkrivaju
smetnje.
Programski paket LabVIEW, u elektroenergetici, se primjenjuje u području
mjerenja I kontrole električne energije, upravljanju obnovljivim izvorima energije,
nadzor elektrana te može pružiti rješenje nastalih problema.
LabVIEW se, u diplomskom radu, koristio kako bi se razvila aplikacija za nadzor
električnih veličina i dojavu nenormalnih pogonskih stanja transformatora. Aplikacija
obuhvaća test magnetizirajućih struja koje je potrebno nadzirati zbog provjere stanja
na jezgri transformatora.

Abstract (english)

Transformer is a key element of the power system transmission and distribution
of electricity, and it is necessary to constantly monitor and protect it against faults and
abnormal operating conditions.
The work contains failures and malfunctions that may occur during operation of
transformers and necessary monitoring of the required parameters that reveal
malfunctions.
LabVIEW is applied in the field of measurement and control of electrical energy,
renewable energy resources management, monitoring powerplants and it can give us
solutions to encountered problems.
In the work, LabVIEW has been used to develop an application that will monitor
electrical parameters and alarm about any abnormal operating condition of the
transformer. The application includes transformer magnetization current test because
it’s important for obtaining informations about transformers core.
