AN EARTHING SYSTEM FOR A WIND TURBINE CONNECTED TO A UTILITY GRID AND FOR A WIND TURBINE PARK

摘要

The invention relates to an earthing system for a wind turbine connected to a utility grid. The wind turbine comprises at least one electric system such as low or high voltage power systems and cables (16), at least one control system such as a SCADA system and control cables (18), and/or at least one safety system such as a lightning protection system, wherein a connection to an electrically earth potential is established from one defined place (12) within the wind turbine for said systems.
