A First approach on the new transmission system in northern Brazil
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 ...
Comparison of algorithms for loss allocation in transmission networks considering power redispatch
An analysis of the performances of three important methods for generators and loads loss allocation is presented. The discussed methods are: based on pro-rata technique; based on the incremental technique; and based on ...
Dynamic behavior of a linear induction motor
Although conventional rotating machines have been largely used to drive underground transportation systems, linear induction motors are also being considered for future applications owing to their indisputable advantages. ...

Modelling of the influence of the layer pollution thickness in high voltage polluted insulators
An experimental model and a mathematical model with the introduction of a ramp in the channel of Obenaus model are presented. The aim is to present a better reproduction of the real layer pollution deposited on the HV ...
Electric field and electric potential due to a finite cylindrical surface charge distribution considering a linearly variable surface charge density
(IOS Press, 2016-08)
This paper proposes a fast and accurate method for determining the electric potential and the radial and axial components of electric field intensity produced by a finite cylindrical surface charge distribution. The surface ...
A new South American network to study the atmospheric electric field and its variations related to geophysical phenomena
In this paper we present the capability of a new network of field mill sensors to monitor the atmospheric electric field at various locations in South America; we also show some early results. The main objective of the new ...
