Lightning Protection of Overhead Power Distribution Lines
Distribution lines are often located in areas with high ground flash densities, being therefore subject to lightning-caused power interruptions. This paper presents an overview of the various types of lightning overvoltages that can arise on overhead power distribution networks, as well as typical voltage waveforms. The effectivenesses of the most important methods for mitigating such overvolta...
متن کاملTransient Analysis of the Single-Conductor Overhead Lines Connected to Grid-Grounded Arrester under Direct Lightning by Means of GA
In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...
متن کاملEvaluation of Arrester’s Protection Levels during Lightning Strikes to Overhead Medium Voltage Lines
This paper present an evaluation of overvoltages in low-voltage LV installation in buildings in cases of direct lightning strikes to overhead medium voltage lines. The study considered typical power systems with lowand medium voltage surge arresters. The calculation have been performed using the EMPTATP
متن کاملPerformance of Medium Voltage Overhead Distribution Lines Against Lightning Discharges
The lightning discharges are one of the main causes of interruptions of medium voltage overhead distribution lines, being the reason of great concern for the utility companies. Its destructive effects frequently extends to equipments and connected installations, with the possibility to cause personal injuries and material damages, beyond economic losses, due to out of income and the possibility...
متن کاملapplication of intelligent water drops (iwd) in transient analysis of overhead lines terminated to grid-grounded arrester under direct lightning
in this paper, intelligent water drop algorithm (iwd) is used to analyze single overhead line connected to grid-grounded arrester. in this approach, at first norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (mom) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. finally applying inte...
