A method and system for directly measuring the compression of a ripple spring () in a dynamoelectric machine through a corresponding wedge (). A compression-assessment tool () is provided that includes a carriage () for supporting a proximity sensor (). The carriage () enables the proximity sensor () to be passed over the length of the ripple spring (), which produces an output signal that is representative of the compression of the ripple spring ().

A remote controlled inspection vehicle provides interchangeable modules, permitting the vehicle to be easily configured to perform a wide variety of tasks. The vehicle includes at least one frame module having a pair of drive modules on either side. Each drive module includes a continuous track surrounding a permanent magnet, and is dimensioned and configured to pivot around its longitudinal axis. The frame modules are dimensioned and configured to be hingedly secured to other frame modules, end effectors including various sensors for performing inspections, and tail units to assist in placing the vehicle in the desired environment.

An improved apparatus for impact testing stator wedge tightness in an electrical generator includes a base assembly that has a vibration sensor mounted thereon and is adapted to temporarily attached to a stator core lamination in an electrical generator, an impact assembly for creating an impact against the stator core lamination; and a mounting system for mounting the base assembly to the impact assembly. The mounting system includes an isolating system for vibrationally isolating the base assembly from the impact assembly during use, so that the vibration sensor will receive vibrations from the stator core lamination, and not said impact assembly. The method of use is also disclosed.
