Abstract
System, methods, and devices for inspecting generator rotor slot wedges in-situ are provided. The system includes a controller operably connected to a remote-control carriage for transmitting control signals and receiving data. The carriage includes a drive module for moving the carriage into an inspection area, e.g., through an air gap between the rotor and stator, and an inspection module operable to inspect a rotor wedge surface. The inspection module includes a jack assembly and a transducer assembly. The jack assembly is operably connected to the transducer assembly, and configured to elevate the transducer assembly to the rotor wedge surface for inspection.
