Beschreibung
Zusammenfassung:	A wind turbine (101) is provided. The wind turbine (101) includes a transformer (150) having a low-voltage side (151) and a high-voltage side (152). The transformer (150) is configured to step up a voltage of the low-voltage side (151) of the transformer (150) to a voltage of an external grid (200, 300). The wind turbine (101) further includes an electrical power generating unit (118) which is connected to the low-voltage side (151) of the transformer (150) and configured to feed an ac-power to the low-voltage side (151) of the transformer (150). A charging device (130, 131, 132) of the wind turbine (101) is connected to the low-voltage side (151) of the transformer (150) and configured to charge the low-voltage side (151) of the transformer (150) when the electrical power generating unit (118) does not feed ac-power to the low-voltage side (151) of the transformer (150).
