Lightning discharges, usually as Rayo conoces, ¿that are due? ¿Sus potential? How protegernos?
... he most common system of protection is it pararrayos the captor, su discharge function is to attract and lead them to land safely and dissipate through a system of electrodes so as not to cause injury to people or buildings.
This contraption was invented in 1753 by Benjamin Franklin while performing a series of experiments on the property that have sharp points, placed in contact with the ground, discharging electrified bodies located in the vicinity.
This first lightning is known as "Lightning Franklin" in honor of its inventor.
The main objective of lightning is to avoid direct impact on the protection zone to protect people, animals and plants that are within it.
These discharges from storms, and are more common at high altitudes to sharp metal spikes. These discharges are produced by the union of positive charges and negative charges in the cloud, the cloud is positively charged at the top and the bottom negatively when the power exceeds the dielectric strength of the medium in which colliding loads is resulting in lightning.
Finally it should be remembered that metal objects by flowing electricity creates a magnetic field therefore attract the shock, hence the importance of disconnecting the electrical and electronic equipment during storms as it could discharges into the draw.
