ABSTRACT:
The method includes sealing the stator bar end connections from within the stator bar end fitting. Particularly, a low viscosity epoxy is initially applied from within the chamber of the end fitting by use of a boroscope and a syringe-type applicator, the low viscosity epoxy being applied to all joints between the adjacent strands of the stator bar and between the fitting and the outermost strands of the stator bar. A high viscosity epoxy is then applied over the low viscosity epoxy using the boroscope and applicator to provide a thick barrier seal between the liquid coolant in the chamber and the brazing material. The epoxy is then cured. The process ensures that the brazing material is isolated from the liquid coolant by the barrier seal whereby potential leaks are prevented and partially developed leaks or leaks extant are arrested because sealant material is disposed at the liquid coolant/braze interface.
