20.500.12556/DKUM-18078 UPORABA SKOZNJIKOV V DISTRIBUCIJSKEM OMREŽJU USE OF BUSHINGS IN DISTRIBUTION ELECTRICAL POWER SYSTEM Namen diplomske naloge je bil raziskati problematiko pri uporabi skoznjikov v distribucijskem omrežju in narediti kosovni preskus na 24 kV ameriških skoznjikih proizvajalca Piedmont Dielectrics Corporation. Preskusi so bili izvedeni na neuporabljenih skoznjikih in na tistih, ki so obratovali deset let. Opisani so tudi postopki za preskušanje srednjenapetostnih skoznjikov in merilna proga za meritev delnih praznitev. Vse meritve so bile izvedene v Infrastrukturnem centru za izvajanje energetskih meritev – ICEM, ki se nahaja ob elektrarni Mariborski otok. The purpose of this diploma thesis was to investigate the problems with the use of bushings in distribution electrical power system and to make regular test on 24 kV bushings, designed and manufactured in United States of America by Piedmont Dielectrics Corporation. The tests were performed on the unused and the ten-year-old bushings. I have described the test procedures for medium voltage bushings and the test circuit for partial discharges. All measurements were made in Infrastructural Centre for Energy Measurements – ICEM, which is placed next to the power station Mariborski otok. skoznjik okvare delne praznitve bushing failure partial discharge true true false [T.
