Estimation of the Lightning Performance of Overhead Lines Accounting for Different Types of Strokes and Multiple Strike Points

Dealing with lightning performance computation, researchers usually consider only negative downward first return strokes and the relevant channel-base peak current distribution. The aim of this article is to account for the lightning flash mechanism, which ...

Incidence of Upward Lightning Triggered by Nearby Lightning: A Monte Carlo Simulation

Marcos Rubinstein, Antonio Sunjerga

Upward lightning is the dominant type of lightning discharge to tall structures. It has been observed that a significant number of these upward flashes are initiated by nearby lightning activity. The aim of this study is to estimate the incidence of upward ...

The Propagation Effects of Lightning Electromagnetic Fields Over Mountainous Terrain in the Earth-Ionosphere Waveguide

Marcos Rubinstein, Mohammad Azadifar, Dongshuai Li

In this paper, a full-wave two-dimensional Finite-Difference-Time-Domain model is developed to evaluate the propagation effects of lightning electromagnetic fields over mountainous terrain in the Earth-ionosphere waveguide. In the model, we investigate the ...

On Practical Implementation of Electromagnetic Models of Lightning Return-Strokes

Hamidreza Karami

In electromagnetic models, the return-stroke channel is represented as an antenna excited at its base by either a voltage or a current source. To adjust the speed of the current pulse propagating in the channel to available optical observations, different ...

On the possible variation of the lightning striking distance as assumed in the IEC lightning protection standard as a function of structure height

Carlo Alberto Nucci

The effect of structure height on the lightning striking distance is estimated using a lightning strike model that takes into account the effect of connecting leaders. According to the results, the lightning striking distance may differ significantly from ...

Effects of nearby buildings on lightning induced voltages on overhead power distribution lines

Mario Paolone, Carlo Alberto Nucci

For the case of urban overhead lines, the presence of nearby buildings is expected to affect the overvoltages induced by nearby cloud-to-ground lightning return strokes. So far, this effect has been seldom taken into account in the literature on the subjec ...

Lightning Return Strokes to Tall Towers: Ability of Engineering and Electromagnetic Models to Reproduce Nearby Electromagnetic Fields

Marcos Rubinstein, Davide Pavanello, Abdolhamid Shoory, Seyed Abbas Mosaddeghi

We present measurements of nearby vertical and horizontal electric fields from leaders and return strokes associated with lightning strikes to the 100-m-tall Gaisberg Tower in Austria obtained in 2007 and 2008. The fields were measured at a distance of abo ...

Compensation of the Instrumental Decay in Measured Lightning Electric Field Waveforms

Marcos Rubinstein, José-Luis Bermudez

The proper characterization of lightning electric and magnetic fields is very important for a number of reasons, such as the study and design of lightning protection and the validation of return stroke models. Also, an accurate late time response of the se ...
