Abstract

V doktorski disertaciji sta predstavljena zasnova in razvoj naprave za sprotno ocenjevanje stanja prenapetostnih odvodnikov brez iskrišč. Naprava je namenjena vgradnji na ozemljitveni del prenapetostnega odvodnika in uporabi pod napetostjo. Zaradi nedostopnosti in večjih razdalj do vgradnega mesta prenapetostnega odvodnika je naprava opremljena s komunikacijskim sistemom, ki omogoča pošiljanje podatkov meritev prenapetostnih odvodnikov ne glede na lokacijo. S pomočjo dobljenih meritev celotnega uhajavega toka prenapetostnega odvodnika je s pomočjo predstavljenega algoritma, ki izkorišča razmerje med celotnim uhajavim tokom in uporovno komponento uhajavega toka, možno določiti stanje prenapetostnega odvodnika. Po interpretaciji je meritve možno posredovati preko prenosa podatkov na strežnik in kasneje do pristojnih vzdrževalnih služb v kontrolnem centru.

Secondary title: Real time assessment of surge arrester state in electric power grid
Secondary abstract: This doctoral dissertation presents the development of the theoretical background and the design of an electronic device for monitoring the condition of a gapless Metal Oxide Surge Arrester. The device is intended to be used online. Due to the inaccessibility and possible remote location of most surge arresters, it is equipped with a communication system, allowing the device to convey the measurement of the surge arrester characteristics under any conditions. By gathering measurements of the surge arrester’s total leakage current, it is possible, on the basis of the ration between the total leakage current and the resistive component of the leakage current, to determine the condition of the MOSA. After interpreting the results, these can be sent via a data transfer unit to a server, which, in turn, sends it onward to the authorized personnel through the surge arrester control center.
