Abstract: A generator grounding module selectively mountable to a support bracket and selectively engageable with a rotor includes a plate member movable along a mounting axis to selectively attach the generator grounding module to the support bracket, the plate member movable between a first position and a second position in which the plate member is substantially fixed with respect to the support bracket. A mounting block is movable along the mounting axis with respect to the plate member, a grounding strap is coupled to the mounting block and is movable between a disengaged position and an engaged position in which the grounding strap contacts the rotor, and a biasing assembly is connected to the plate member and the mounting block and operable to bias the mounting block along the mounting axis toward the plate member, wherein the plate member is fixedly attached to the support bracket when in the second position and the biasing assembly biases the grounding strap into the engaged position.

Abstract: A tool system for tightening a retrightenable wedge system in a slot of a generator stator core is presented. The tool system includes a carriage assembly and a wedge tool assembly that is pivotally coupled to the carriage assembly. The carriage assembly includes motorized drives that axially moves the tool system along the slot and holds the tool system on the slot at an axial position. The wedge tool assembly includes a torqueing socket to tighten the retightenable wedge assembly in the slot. The torqueing socket is driven by a worm gear arrangement.

Abstract: A retightenable wedge system for tightening a coil in a slot of a generator stator bar is presented. The retightenable wedge system includes a first filler layer, a spring member, a second filler layer and a retightenable wedge assembly. The retightenable wedge assembly includes a slot wedge having an aperture, a tightening member having form fit feature and a locking member having mating form fit feature. The tightening member is tightenable in the aperture such that a radial load is applied on the second filler layer for tightening the coil in the slot. The tightening member is locked in place in the aperture by an engagement between the form fit feature of the tightening member and the mating form fit feature of the locking member such that the tightening member is restrained from backing out of the slot wedge.
