The invention relates to a tower (11), in particular a tubular tower (11), of a wind energy installation (10) with a current conduction means system (25, 35) for transmitting electrical power from a generator, preferably arranged on the tower (11), to a power module, preferably formed at the base of the tower. The tower (11) is developed in that the current conduction means system (25, 35) has three electrical conductors (27.1, 27.2, 27.3; 37.1, 37.2, 37.3; 45.1, 45.2, 45.3) arranged next to one another, and the three electrical conductors (27.1, 27.2, 27.3; 37.1, 37.2, 37.3; 45.1, 45.2, 45.3) are arranged in a housing (26, 36, 46), wherein, using the housing (26, 36, 46), a or the PE conductor is designed for the electrical conductors (27.1, 27.2, 27.3; 37.1, 37.2, 37.3; 45.1, 45.2, 45.3) arranged in the housing (26, 36, 46), wherein the housing (26, 36, 46) is connected to the, preferably inner, tower wall at predetermined distances using connecting devices, wherein the connecting devices have electrical cross sections conducting with the tower wall, wherein the distances between the connecting devices in the longitudinal extent of the tower (11) and the cross sections of the connecting devices between the housing (26, 36, 46) and the tower wall are dimensioned such that, in the event of a fault, the voltage drop between the tower wall and the housing (26, 36, 46) does not exceed a predetermined touch voltage. In addition, the invention relates to a wind energy installation (10) with a tower (11), in particular a tubular tower (11), and to a method for operating a wind energy installation (10) with a tower (11). |
