The components of Lightning Protection System (LPS) are exposed to direct lightning strikes and corrosive atmosphere. To achieve efficiency, the materials should have high current withstanding capacity and the materials should be less corrosive. The current carrying capacity of a material depends on the cross sectional area and the materials should be selected based on […]
The Earth electrodes should be designed to withstand the fault current without any physical damages. The fault current carrying capacity of a material mainly depends on cross sectional area of that particular material. In this article, we shall discuss about the current carrying capacity of pipes and strips of different dimensions and different materials as […]
Introduction: Taller buildings in general attract lightning strikes, hence an efficiently designed LPS is highly critical to safeguarding these structures from the destruction caused due to lightning. Also, such structures should make sure quality earthing systems and surge protection devices are installed to protect the lives and expensive electronic equipment housed in these structures. National […]
The earth resistivity extremely varies between 1 to 10,000-ohm meters and in most situations, the soil resistivity is found to be non-uniform. Variation of the soil resistivity in depths is more predominant as compared to the variation with same in the horizontal distance and this happens due to stratification of earth layer. Measurement of earth […]
The Earthing Resistance of any electrode is made up of the following factors: • Resistance of the (metal) electrode, • Contact resistance range between the electrode and the soil • Resistance of the soil from the electrode surface outward in the geometry (which is set up for the flow of current outward from the electrode) […]
Introduction Lightning is one of the most destructive phenomena of nature. It causes maximum damage to living beings and to the equipment across the globe. Due to the storage of explosive and hazardous materials in the Oil & Gas Industry, a direct lightning strike or secondary surges could lead to major disasters leading to loss […]
When structures are containing protruding or flush-mounted structures, the Lightning protection is designed in such a way that those parts lie within the protection given by air terminal rods mounted over the structure. The above picture depicts that the protruding structure lies within the region of protection given by the lightning rods. However, additional protection […]
Lightning is one of the most destructive phenomena of nature. It can cause damage to humans, structures, electrical and electronics equipment. Currently, due to global warming, the entire world is moving towards Renewable Energy, and Solar Panels are at high risk due to the possibility of destruction by lightning strikes due to its elevation and […]
