Scientists now estimate that for every additional degree of global warming, thunderstorm activity increases by 10%. That is why we are witnessing in recent years an upsurge of events related to lightning, in several countries of North Africa.<\/span><\/p>\n

With approximately 32 million discharges per year worldwide, lightning strikes statistically 50 to 100 times per second. It is a major cause of death in the world, with a rate of 6 deaths\/million\/year or more than 40,000 deaths annually.<\/span><\/p>\n

From a financial point of view, the annual cost of damage is in the tens of billions of dollars. In the USA alone, the cost of lightning damage in 2011 was estimated at 1 billion USD. <\/span><\/p>\n

The effects of lightning can be direct, as when it strikes a building roof, a transmission tower or an electrical transmission cable, for example.<\/span><\/p>\n

But its most frequent effects are rather indirect: ground rise, because of the step voltage, coupling phenomena by inductive radiation, and disturbance transmissions by capacitive crosstalk. <\/span><\/p>\n

Protection against direct lightning strikes is achieved by lightning conductors placed above the structures to be protected, while protection against indirect effects is achieved by lightning arresters and surge protectors judiciously placed at the level of the electrical installation.<\/span><\/p>\n
