Autor: Sandro de Castro Assis, Wesley Edney Sousa, Wallace do Couto Boaventura

Publikováno v: IEEE Latin America Transactions. 16:96-104

The need to supply the demand for electricity of large urban centers and large industrial customers has challenged the planning and design of 69kV and 138kV transmission lines. Typically, such voltage levels require conventional infrastructure, with

Effects of Considering A Stroke Angle Distribution on Estimating the Shielding Performance of Overhead Transmission Lines

Autor: Sandro de Castro Assis, Marco Aurélio O. Schroeder, André T. Lobato, Rodolfo A. R. Moura, Luiz Carlos do Nascimento, Warlley S. Sales

Publikováno v: Journal of Control, Automation and Electrical Systems. 26:567-578

The shielding analysis method recommended by the IEEE Working Group on Estimating the Lightning Performance of Transmission Lines is based on the Electrogeometric Model and the concept of striking distance. The simplistic assumption of a vertically d

Assessment of a frequency dependent soil model impact on lightning overvoltages

Autor: Maria Teresa Correia de Barros, Rodolfo A. R. Moura, Marco Aurélio O. Schroeder, Sandro de Castro Assis, Antonio C. S. Lima, Marcio Matias Afonso

Publikováno v: 2016 33rd International Conference on Lightning Protection (ICLP).

A key aspect in the evaluation of the lightning performance of an overhead line is the tower grounding modeling approach. It affects the insulator string overvoltages and the ground potential rise (GPR). This work aims to assess the impact of the soi

Analysis of the cumulative probability distribution of the stroke angle in lightning incidence to three-phase overhead transmission lines

Autor: Rodolfo A. R. Moura, Maicon R. Reis, Warlley S. Sales, Marco Aurélio O. Schroeder, Douglas E. Cruz, Luiz Carlos do Nascimento, André T. Lobato, Sandro de Castro Assis

Publikováno v: 2013 International Symposium on Lightning Protection (XII SIPDA).

Lightning leaders follow a random behavior when approaching ground surface, so the usual assumption of a vertical stroke is not realistic. This paper is aimed at analysing the sensitivity of the shielding failure flashover rate (SFFOR) of three-phase
