Abstract: A system for relieving pressure from within a generator casing can include a generator shaft defining a shaft channel therein and at least one rotating valve disposed within the shaft channel of the generator shaft and in fluid communication with an interior of the generator casing and the atmosphere. The rotating valve is configured to allow fluid within the generator casing to flow through the generator shaft to the atmosphere in an open state and while rotating. The rotating valve is configured to prevent fluid within the generator casing from flowing in a closed state.
