Abstract

A seal is provided at the intersegments of hydrogen seal rings for preventing oil leakage through this potential gap between the seal ring segments. By minimizing leakage through the gaps between the open rings, hydrogen consumption in hydrogen-cooled generators due to leakage oil is reduced. In a preferred embodiment, the seal is provided by a brush seal secured to one of the seal ring segments and received in a slot defined in the other of the seal ring segments.
