Abstract
A method for sealing fluid cooled conduits in-situ for a generator is provided. The fluid or liquid cooled conduits are located external to a stator of the generator and substantially outward of stator bars. The method includes draining coolant from the fluid cooled conduits, and drying interior surfaces of the fluid cooled conduits. In inserting step inserts a borescope and a sealant applicator through an opening in one of the fluid cooled conduits. A locating step locates a brazed joint in the fluid cooled conduit, and a positioning step positions the borescope and the sealant applicator near the brazed joint. An applying step applies a sealant to the inside of the fluid cooled conduit at the brazed joint A viewing step may be used to view the brazed joint with the borescope to confirm that the applying step has been successful.
