They are mechanical devices that are used to distribute lubricating oil within a generator. They are typically located near the rotor shaft and consist of a ring with small holes that allow oil to splash out and lubricate the bearings and other internal components of the generator. The oil is usually stored in a reservoir within the generator and is forced out by centrifugal force as the rotor spins. Oil splash rings help to ensure that the generator is properly lubricated and that the internal components are protected from wear and tear. They also help to keep the temperature of the generator under control by dissipating heat through the oil.
