A plurality of electrically conductive elements is arranged in spaced-apart manner on the structure, and the elements are in contact with the conductive paint layer. A protective coating is arranged on the surface coating and comprises a material that is thermally insulating and electrically conductive. The protective coating covers the electrically conductive elements in part.
