Abstract: A hydraulic testing and drying apparatus for a water cooled-stator in an electrical generator. The apparatus is mounted on a sled (10) and comprises an air compressor (16), regenerative air dryer (18), receiver (20), vacuum pump (22) and associated piping and control devices. After the receiver is coupled to the inlet to a stator winding, dry and clean compressed air pressurizes the receiver and stator winding. Pressure activates valves between the compressor and receiver, and at the drain of the stator winding operate so that the pressurized air purges moisture from the stator windings. Through the use of pressure activated switches, cycles of pressurization and purging are run automatically. Hygrometer sensors monitor the dewpoint of the air entering the generator and of the air exhausting from the generator. A vacuum pump (22) creates a vacuum within the stator winding to complete drying and to test the decay of a vacuum in the stator windings.

Abstract: A technique is disclosed for drying and curing a liquid film applied to a former which is reactive to radio frequency energy so as to generate heat. A liquid film, such as latex, is applied to a metallic former which is then disposed in the proximity of an applicator which propagates radio frequency energy. In response, by a process of induction the former generates heat and thereby advantageously dries said film in an inside-to-outside manner. A superior product is produced which is substantially free of defects and blemishes.
