The arrangement of an electric machine, a connecting system and a converter, includes the connecting system connected between the electric machine and the converter. The connecting system has an enclosure that houses non-shielded conductors each non-shielded conductor is connected between a phase of the electric machine and the inner side of the converter. The non-shielded conductors of the connecting system that are connected to an operating phase of the electric machine are adjacent to conductors of the connecting system that are not connected to operating phases of the electric machine.

An electric generator () includes a casing () that envelops a stator () and a rotor (). The casing () has an aperture () through which the generator casing inside () is inspectable during generator operation. A method includes inspecting during generator operation, through the aperture () of the casing (), the casing inside ().

Electric generator and method for inspecting an electric generator

A cooling system for bushings of an electric generator, which includes a casing housing a stator and a rotor connected to a rotor shaft activating at least a fan defining at least a high pressure zone and a low pressure zone. The generator has a plurality of phases electrically connected to hollow phase rings that are electrically connected to bushings supported by the casing and having cooling circuits to let a cooling medium pass through them to cool them. The outlets of the bushing cooling circuits are housed in the high pressure zone and are connected to inlets of the hollow phase rings. A method for cooling the bushings of an electric generator is also provided.
