Abstract

In this work is presented in a simulated environment, the analysis of the required length of conterpoise cable connected to the ground rod in a transmission line located in Maceio, Brazil, capable of avoiding the phenomenon known as back flashover, in other words, the disruptive discharges of return in the chain of insulators when subjected to standardized atmospheric discharges considering some values of soil resistivity and some types of arrangement of geometric arrangements of grounding systems.

Abstract

Polymeric insulators used in 13.8 kV distribution network are presenting premature damage due to cavity inner dielectric. With the objective to develop a diagnostic process, it was constructed an experimental distribution line in Universidade Federal de Pernambuco (UFPE) campus. In this article it will be described this experimental line characteristics and performed studies to plan its construction.
