Effect of the grounding system on the lightning current profile along a tall structure

Lightning analysis of adjacent grounding systems using multi-conductor transmission line method

“…However, when these currents circulate through the ground, they may also flow through any other metallic installations like adjacent grounding electrodes. This phenomenon may transfer dangerous potentials from one grounding system to the other which is not directly affected by the faults or high‐frequency currents [1, 2]. Also, these currents can be transferred to devices connected to the adjacent grounding systems and cause erroneous operations, malfunctions or even the destruction of electronic devices, particularly those using modern electronic circuits which generally have weak signal levels.…”

Transient behaviour of grounding electrodes in uniform and in vertically stratified soil using state space representation

“…Electrical installations must have an adequate protection to avoid damage caused by lightning current [1,2]. The main role of lightning protection systems is to convey lightning current to earth via grounding systems [3,4].…”

Model of ferromagnetic steels for lightning transient analysis

“…Structural steels are the essential components of large grounded structures, such as buildings [1][2][3], towers [4,5] and others [6]. These components are not the part of the electrical equipment, but conduct surge currents when exposed to lightning discharges or other unpredictable transients.…”
