A tutorial about tower transmission models for the analyses and prediction of backflashovers
(Ieee-inst Electrical Electronics Engineers Inc, 2017-08-01)
Lightning is one of a main causes of sudden outages in the power systems. When a lightning strikes the ground wires or directly to transmission tower, a backflashover may occur. It consists of an electric arc from the tower ...
A First approach on the new transmission system in northern Brazil
(2011-12-01)
This article shows an analysis of the electrical parameters of a three-phase transmission line section using a relatively new design for steel towers characterized by 280 meters high. These main features, the height of the ...
Overvoltage analysis of transmission towers considering the influence of tower-footing impedance
(2017-11-21)
Lightning is one of the main causes of outages due to backflashover mechanism in power systems. In this context, the tower-footing impedance presents a key role in the overvoltages caused by this phenomenon. Tower-footing ...

Lightning is one of the main causes of outages due to backflashover mechanism in power systems. In this context, the tower-footing impedance presents a key role in the overvoltages caused by this phenomenon. Tower-footing ...
Introduction of a non-conventional solution for Amazon transmission system: Analysis of the electric aspects
(2011-12-09)
This article shows an analysis of the longitudinal electric parameters of a three-phase transmission line/section using a 280-meter high steel tower. This characteristic, the height of the line conductors and distance ...
Analysis of the electrical characteristics and surge protection of EHV transmission lines supported by tall towers
(Elsevier B.V., 2014-05-01)
The electrical characteristics of a new 280-m-tall transmission line are analyzed. The geometrical distance of the phases, wires height and physical structure of the line are intrinsic associated with its electrical ...
Analysis of the Electrical Characteristics of an Alternative Solution for the Brazilian-Amazon Transmission System
(Taylor & Francis Inc, 2011-01-01)
This article analyzes the electrical parameters of a 3-phase transmission line using a 280-m-high steel tower that has been proposed for the Amazon transmission system in Brazil. The height of the line conductors and the ...
