Earth-termination system

The earth-termination system of a wind turbine has the following functions:
• Protective earthing
• Functional earthing
• Lightning protection earthing

 

An efficient earth-termination system is vital to disperse lightning currents and prevent the wind turbine from being destroyed. From a lightning protection point of view, it is advisable to implement a single, common earth-termination system for all purposes.

To this end, foundations made of reinforced concrete should be preferably used Erdungsanlageas earth electrode because they have a low earth resistance and provide an excellent basis for equipotential bonding. Foundation earth electrodes make both technical and economical sense and must be designed and installed as per DIN 18014.
