A generator rotor lead path configuration includes a plurality of electrically conductive components attached to each other. These components may include an axial lead, a flexible connector, an intermediary, a radial lead, and/or a J-strap. The improved lead path inhibits, if not prevents, lead path failure. A method of assembling or fitting the lead path into a generator is also provided, as well as a method of replacing or retrofitting a lead path that is susceptible to failure with the improved lead path configuration. Assistance in determining causes of lead path failure and ways to overcome lead path failure are also provided.

A rotor pole crossover connection joint for use in a rotating electrical machine is disclosed. The connection joint integrally couples a bottom rotor coil strap to a rotor pole crossover connector with a single piece connector that reduces, distributes or otherwise tolerates stress concentrations in the connector. A corresponding method of forming a rotor pole crossover connection and a rotor assembly including a rotor pole crossover connection joint are also disclosed.

A steam flow control valve for controlling large fluid flow rates, the valve having a reduced response to vibrational excitations experienced during throttling. A valve stem extending outward from the valve body and connected in the valve to a valve plug is guided by a substantially rigid cylindrical bushing extending substantially through the valve body. The bushing has an inner surface for guiding movement of the valve stem and an outer surface for guiding movement of the valve plug. The plug includes an inner annular guide ring about an upper edge for sliding along the outer surface of the bushing and limiting transverse motion.

A valve plug having a valve plug housing shaped to fit in a bonnet cylinder of steam control valves has a pressure seal ring groove for holding a pressure seal ring therein. The pressure seal ring groove has a pair of walls and a bottom surface end and antiwedging relief groove formed in one wall of the pressure seal ring groove adjacent the bottom surface thereof to prevent the wedging of a pressure seal ring between a valve plug and a bonnet cylinder bore wall. The pressure seal ring wears a step in the contact surface to allow the wedging which can otherwise prevent the valve from closing as required for turbine overspeed protection. The valve plug housing pressure seal ring groove can be annular groove having an annular pressure seal ring therein and the relief groove can be annular groove formed in one wall of the pressure seal ring groove adjacent the pressure seal ring along the seal ring contact surface of the pressure seal ring. The relief groove has a pair of sidewalls and a bottom surface with one wall forming an extension to the pressure seal ring groove bottom surface so that wear on the pressure seal ring groove wall enlarges the width of the pressure seal groove to prevent a step forming therein and wedging of the pressure seal ring between the valve plug and the bonnet cylinder bore.
