A turbine generator with stator windings and a hydrogen pressured stator frame, includes an annular L-shaped collar affixed across a circumference of the stator frame and soldered thereto by a solder joint; a terminal plate anchored to the collar across the circumference of the stator frame and marginally separated from the collar to form a first annulus that contains a first sealant composition that interfaces with the solder bond; and a hardening sealant applied to an upper portion of the solder joint. A high voltage turbine generator is sealed by filling a first annulus formed between an annular L-shaped collar affixed across a circumference of the stator frame and soldered thereto by a solder joint and a terminal plate anchored to the collar across the circumference of the stator frame with a first sealant composition; applying a hardening sealant onto the solder joint; and coextensively covering the first sealant composition and the applied hardening sealant with a second sealant composition.
