Abstract: A system for passivating a plurality of hollow copper strands in a stator water cooling system including; a first storage tank containing a cleaning solution, a second storage tank containing rinsing water; a third storage tank containing a passivation solution; a plurality of conduits connecting the first, second, and third storage tanks in a closed loop with the plurality of hollow copper strands; and an alkaline pump for pumping the cleaning solution, the rinsing water, and the passivation solution through the closed loop.

Abstract: A generator has a bore connector having a threaded radial opening for receiving a sectional terminal stud. The terminal stud includes an adapter section having threads on a radial inner end thereof for threaded engagement with the bore copper and a recess at its opposite end. An outer section of the terminal stud is received in the recess, making electrical connection therewith through an electrical connector. The outer section is maintained in the radial bore of the rotor by a threaded nut. The rotational orientation of the adapter section is fixed by its threaded engagement with the bore copper, while the outer section can be inserted without regard to rotational orientation, thereby facilitating refurbishment of the generator without remachining the bore copper.
