An apparatus having a slidable seal and related methods to prevent leakage of hydrogen gas or other fluids in a power generator is provided. The seal can connect to a high-current conductor when slidably contacting the surface of a fluid channel formed around the conductor. The seal slidably moves relative to and maintains contact with the surface of the fluid channel. The seal preferably includes a seal body having an abrasion abatement layer of soft metal to prevent abrasions of the seal surface as it slidably moves relative to the fluid channel. The seal can include at least one sealing gasket positioned to fit within a sealing gland formed in the fluid channel. Alternatively, the seal can have at least one sealing gasket positioned in a sealing gasket formed in the seal body and an insulating gasket positioned to restrict the flow of seal-degrading electrical currents in the seal.

Protected seal and related methods for sealing fluid in power generation system

A compliant clamp (20) for a power generator and associated methods are provided (see FIG. 5). The clamp (20) preferably includes an end plate (18) mounted to an end of a generator stator core (10) and a core attaching member (15) connected to the generator stator core (10) and positioned to connect the generator stator core (10) to a frame (12). The core attaching member (15) preferably has at least an end portion (22) extending outwardly from the end plate (18). At least one spring member (25) is preferably mounted to the end portion (22) of the core attaching member (15) for springingly biasing the end plate (18) inwardly toward the generator core (10). The clamp (20) further includes at least one retaining member (23) mounted to the end portion (22) of the core attaching member (15) for retaining the spring member (25) on the end portion (22) of the core attaching member (15), a current shunt member (30) mounted to the end portion (22) of the core attaching member (15), having at least one portion abuttingly contacting the end plate (18), and having another portion abuttingly contacting the retaining member (23) to thereby provide a current shunt path from the retaining member (23) to the end plate (18), and at least one insulating member (26) mounted to the end portion (22) of the core attaching member (15) and positioned between the current shunt member (30) and the at least one spring member (25).
