Electrical Grounding Design of a Wind Turbine

The paper presents an overview of grounding design of wind turbines based on two mainframes: the power frequency grounding resistances and the impulse grounding resistances. Considering every possible way, depending on the variables that are implied in the design process, the grounding resistances are calculated, also the touch voltage and contact voltage has been considered and compared to the standard limit. The paper shows the feasibility of impulse grounding resistances of the adapted design, having different soil resistivity and is compared to the withstand value of safety measure and confirmation of the personal safety is acquired.
