Lightning protection system in wind turbines

Electric lightning strikes and how to protect them Lightning strikes result from the formation of electrostatic charges and their polarization in thunderstorms. Thunder clouds form either as a result of an increase in the temperature of the air in contact with the earth’s surface and its upward movement, then cool, moist air is displaced from…

Classification of Wind Turbines

Variable and Constant Speed Wind TurbinesAlthough known and exploited for a long time, wind energy was completely neglected during the industrial era, for the almost exclusive benefit, except hydroelectricity, of fossil fuels. The kinetic energy of the wind can be directly converted into mechanical energy and be usable for example in old windmills or to…
