Abstract
The cooling system cools the stator and/or the rotor of a generator. Oxidation-resistant cooling channels are provided in the stator and/or in the rotor. Low conductivity for the coolant flowing through the cooling circuit is ensured by feeding fresh coolant into the cooling circuit, whereby the fresh coolant has a lower electric conductivity than the coolant in the cooling circuit.
