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 ().
