Lightning is one of the most devastating natural phenomena. There are many discharges during lightning storms and some of them can even reach hundreds of kiloamperes.

These electrical discharges are a great hazard to people, animals, buildings and electronic equipment. The economic consequences of lightning are also very important; it can cause fire, stop production of a factory or interrupt critical processes. A direct lightning discharge to a person results in current flowing through the body. This current lasts a very short time but the intensity is enough to provoke electrocution resulting in heart failure and causing burns of different degrees.
