Zusammenfassung:	A sealed electric generator includes a casing (2) housing a stator (3) and a rotor (4) connected to a shaft (5), wherein the shaft (5) is provided with a duct housing and a lead (10) carrying electric power from an exciter (8) to rotor field windings (9). The duct has a sealing unit for preventing gas contained inside of the casing (2) from reaching the exciter (8). The sealing unit has first and second seals (20, 21) defining between them a chamber (22), such that gas that leaks past a seal (20, 21) enters the chamber (22).
