"There are two types of power generators. One is turbo generators mainly used by steam turbines. The other is salient pole generators used by hydroelectric power generation which is the most widely used from of renewable energy. Turbo generators and Salient pole generators both use rotating pole to charge up the electromagnetic energy, but the pole each generator uses has unique physical characteristics. This book focuses on the physics and maintenance knowledge of the salient pole generators"--
