Fast-front transients play an important role in the insulation design of any power system.
When a stroke hits the shield wire or the tower of high-voltage overhead power lines …

Jordan's formula to calculate the surge impedance of vertical conductors is revised and
extended to take into account systems with multiple conductors. Experimental data and the …

Various parameters of lightning discharges will be reviewed. Both common negative and
less frequent but potentially more destructive positive and bipolar flashes will be covered …

This study aims to analyze and propose effective methodologies for lightning protection on
university campuses. Lightning strikes can be a potential hazard and can lead to serious …

When lightning strikes a transmission line tower or shield wires, electromagnetic waves
propagate through the tower back and forth, increasing the voltage across insulator strings …

In the present work we assess the lightning performance against direct strokes of overhead
distribution lines, making use of the theory of multiconductor transmission lines with …

A sensitivity study of the lightning flashover rate of transmission lines is presented in this
paper. The study is aimed at analyzing the influence of the tower model on the flashover rate …

In a wind farm, the grounding circuit is a complex electrical system made up of several
interconnected groundings. Its role is very important for the protection of the electrical …

Accurate tower models for fast transients are essential for the insulation design of overhead
lines, since lightning may produce temporary or even permanent faults. The aim of the work …

This paper presents a study regarding the lightning flashover rates of transmission lines
comparing results from calculation procedures and field experience. The proposed …
