Wind Turbines Online for Sale in South Africa | DIY Geek

A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind’s kinetic energy into electrical energy. Larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid.

Wind turbines have an average life of over 25 years, although the most widespread accounting criterion is set for periods of 20 years. Rapid evolution of wind technology has lead to an increase in the durability of wind turbines.

The wind turbine is automatically oriented to take maximum advantage of the kinetic energy of the wind, from the data registered by the vane and anemometer that are installed at the top. The nacelle turns around a crown located at the end of the tower.

The wind makes the blades turn, which start to move with wind speeds of around 3.5 m/s and provide maximum power with a wind speed 11 m/s. With very strong winds (25 m/s), the blades are feathered and the wind turbine slows down in order to prevent excessive voltages.

The rotor (unit of three blades set in the hub) turns a slow axis that is connected to a gear box that lifts the turning velocity from 13 to 1,500 revolutions per minute.

The gearbox transfers its energy through a fast axis that is connected to the generator, which produces the electricity.

All of the critical functions of the wind turbine are monitored and supervised from the substation and the control center in order to detect and resolve any incidents.
