Abstract

U ovom radu analizirana je mogućnost smanjenja broja povratnih preskoka na nadzemnim visokonaponskim vodovima lociranim u područjima sa visokim specifičnim otporom tla.
Dosadašnje aktivnosti na ovom području bile su ograničene postojećom opremom za zaštitu od prenapona. Ovdje su analizirana i uvođenje metaloksidnih odvodnika prenapona njihova primjena u svjetu (prvenstveno u SAD i Japanu). Metaloksidni odvodnici prenapona postali su vrlo kvalitetni, uz sve nižu cijenu, a u svijetu postoje značajna iskustva u njihovoj primjeni kao linijskih odvodnika prenapona.
U radu je izvršena usporedba dosadašnjih svjetskih iskustava te prijedlog budućeg načina uporabe.

Abstract (english)

The possibility of decreasing backflashover numbers on high voltage overhead lines located in regions with high soil resistivity has been analyzed in this study.
Until now, activities in this field of protectioning of grounding systems. World experiences in using line arresters are also presented ( SAD and Japan).
This study is based on facts that metal oxide surge arresters have become very high quality product with low prices, and so many important experiences in using them like line arresters exist in word.
In the conclusion, comparison with knowledge until now has been made, as well as a suggestion for future use.
