20.500.12556/DKUM-85178 Odkrivanje okvar in diagnostika srednje napetostnih in nizkonapetostnih kablovodov diplomsko delo Fault detection and diagnostics of medium and low voltage cables Zanesljivo in varno obratovanje elektroenergetskega sistema je glavna naloga vsakega elektro distribucijskega podjetja. Kablovodi prinašajo številne prednosti, a hkrati tudi težave, ko pride do okvar. Napak na kablovodih ne vidimo, saj je kabel pod zemljo, brez ustreznih merilnih instrumentov pa se lokacije okvare ne more določiti. S tem namenom so bile razvite razne preizkusne in kasneje tudi diagnostične metode, ki jih je možno izvajati na terenu. V teoretičnem delu naloge je predstavljen pregled standardiziranih in uveljavljenih postopkov preizkušanja in diagnostike kabelske izolacije, ki jih je mogoče izvajati s specializiranim merilnim vozilom izdelanim v podjetju Baur GmbH. V praktičnem delu naloge je bilo izvedeno odkrivanje okvar, napetostni preizkus osnovne izolacije in diagnostika kablovoda. The reliable and secure operation of the electricity system is the main task of every electricity distribution company. Cable ducts bring many benefits, but also problems when faults occur. Faults in cable ducts are not visible because the cable is underground, and the location of the fault cannot be determined without proper measuring instruments. To this end, various test and later diagnostic methods have been developed which can be carried out in the field. The theoretical part of the thesis presents an overview of the standardised and established procedures for testing and diagnosing cable insulation, which can be carried out using a specialised measuring vehicle manufactured by Baur GmbH. In the practical part of the assignment, fault detection, stress testing of the base insulation and diagnostics of the cable duct were carried out. okvara kabel izolacija preizkušanje diagnostika defect cable insulation testing diagnostics true true false [J.
