Lightning-Induced Voltages on Overhead Lines-Application of the Extended Rusck Model
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
Lightning-induced overvoltages have a considerable impact on the power quality of overhead distribution and telecommunications systems, and various models have been developed for the computation of the electromagnetic ...
Design and construction of a Reduced Scale Model to Measure Lightning Induced Voltages over an Inclined Terrain
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-07-01)
In this paper is presented the design and construction of a reduce scale model indented to be used for measuring Lightning induced voltages on overhead lines placed over an inclined terrain. Here we present technical details ...
Modelagem para cálculo de tensões induzidas por descargas atmosféricas
(Universidade Federal de Minas GeraisUFMG, 2006-12-19)
Lightning Induced Voltages are known as one of the most important phenomena capable to cause severe damages to electrical systems and telecommunication networks. Despite the lower severity of their effects in relation to ...

Transient Analysis on Multiphase Transmission Line Above Lossy Ground Combining Vector Fitting Technique in ATP Tool
(Ieee-inst Electrical Electronics Engineers Inc, 2022-01-01)
Several approaches to calculate the ground-return impedance and admittance matrices are proposed in the literature. Carson's approach assumes a lossy ground modeled by frequency-independent conductivity where displacement ...
Lightning Induced Voltages on Overhead Lines above Non-Uniform and Non-Homogeneous Ground
(2014-11)
Abstract: lightning induced voltages are one of the most common sources of failures on distribution networks operating in high lightning activity regions. Traditionally, the selection of insulation levels and protecting ...
