An Overview of Lightning Protection System and Its Calculation

Abstract

A rainstorm is fundamentally a tempest, described by lightning and thunder, lightning is a normally happening electrostatic release during which two electrically charged locales in the air or ground incidentally even out themselves, causing the quick arrival of as much as one

gigajoule of vitality. At the point when the temperature rises, hot sodden air rises upwards- known as updrafts. Simultaneously, the cool air sinks downwards, and this is called

downdrafts. The crash between the updrafts and downdrafts makes cumulonimbus mists and it produces lightning and thunder. Tempests happen wherever on the world's surface, one of the most hazardous convective climate occasions. An expected more than 1600–2400 tempests happen at any minute and 50,000 every day, around the globe.1-4 The geographic area of Bangladesh is a shown zone of cataclysmic events like tempest, dry season, flood etc.5 Bangladesh is confronting a long haul environmental change (Over the most recent 25 years normal temperature of Bangladesh expanded by 1.5°C). All rainstorms produce lightning. Lightning damage is a worldwide general medical issue speaking to the main source of climate related demise after tornadoes, streak floods, and typhoons. The wounds cause high mortality and noteworthy long haul grimness. Around the world, mortality from lightning is evaluated at somewhere in the range of 0.2 and 1.7 passings/1,000,000 populace, influencing mostly the youthful and individuals who work outside. Consistently, more than 20,000 individuals are influenced by lightning and a few thousand capitulate to their wounds. Another report shows somewhere in the range of 2,000 individuals are slaughtered worldwide by lightning every year. In Bangladesh, just a couple of studies have been directed on lightning. These uncover that the quantity of lightning occurrences in the nation is very high. Another examination shows that in Bangladesh, the rate of lightning fatalities is 0.9 per 1,000,000 populace for every year, which is higher than in high-pay nations. A sum of 1,476 individuals has kicked the bucket from lightning in Bangladesh during 2010-2016. Preceding 1981, the nation saw lightning strikes all things considered nine days each May. Since that time, the nation has seen strikes a normal of 12 days each May. National rundowns of lightning-related passings and wounds are hard to get in many creating nations including Bangladesh.
