A method for sealing fluid cooled conduits in-situ for a generator is provided. The fluid or liquid cooled conduits are located external to a stator of the generator and substantially outward of stator bars. The method includes draining coolant from the fluid cooled conduits, and drying interior surfaces of the fluid cooled conduits. In inserting step inserts a borescope and a sealant applicator through an opening in one of the fluid cooled conduits. A locating step locates a brazed joint in the fluid cooled conduit, and a positioning step positions the borescope and the sealant applicator near the brazed joint. An applying step applies a sealant to the inside of the fluid cooled conduit at the brazed joint A viewing step may be used to view the brazed joint with the borescope to confirm that the applying step has been successful.

Dynamoelectric device and stator bar therefor, where the stator bar includes a linear portion for positioning in a slot of a stator core, the slot extending in a radial direction relative to an axis of the stator, and an end arm portion having an involute-on-cone bend relative to the linear portion and an elongated cross-section that is substantially aligned with the radial direction of the slot.

A resistance temperature detector (RTD) unit includes an RTD assembly that is removably supported in a central chamber of a support assembly. In a preferred arrangement, the RTD assembly and the central chamber are arc shaped to facilitate removal from the support assembly and to maintain contact surface area. By providing a removable RTD assembly, costs are reduced over current RTD assemblies including two monitoring elements, and the RTD elements can be replaced without dismantling the top bar connections.
