Generator cooling system
Generator cooling system INTRODUCTION In a big turbo-generators where a huge mass of metal is used. As as current flows through conductors large heat is generated in the winding of stator and rotor of generator. When turbo generator is started then heat generation in metallic parts are starting if this heat is not removed from the generator then this is chance to failed the generator winding. As i n generator large amount of heat is generated and is not possible to dissipate this heat from natural system. So forced cooling system is adopted. in force cooling system air or hydrogen gases are used. In smaller turbo-generators, the cooling is by air circulation. In bigger turbo generator hydrogen cooling system came in the field. So e fficient cooling & ventilation system is required for generator to keep temperature of winding bellow certain limits. For the cooling of generator following system is adopted Air cooling system - In this air is forced into the generator
