An inspection system () is for inspecting power generation equipment () and includes a remote receiving device () which receives images captured and transmitted by an inspection apparatus (). A recording device () records the images thereby providing a permanent record of the inspection. The inspection apparatus () comprises: a flashlight assembly () including a power supply (), an elongated housing () having first and second ends (), a lens body () coupled to the first end (), and a lens cover () covering the lens body (). The inspection apparatus () further includes an imaging system () having a camera (), such as a wireless video camera, which is disposed within the lens body opening (), an illumination assembly () which generally surrounds the camera (), and a protective cover () for the illumination assembly (). An associated method is also disclosed.

Method and apparatus for performing remote impact testing for generator stator wedges and ripple springs. An improved low profile carriage is utilized for correlating wedge displacement data with the force required to displace the wedge. A calibrated test stand, in which exemplary wedges are placed under a known loading via a hydraulic load cell, provides means for generating calibration curve sets. From the graphed forcedisplacement curves generated from wedges placed under a known loading, force and displacement data generated during actual stator testing can be analyzed to measure the tightness or looseness of stator wedges, coils and ripple springs. In the preferred embodiment of the low profile carriage of the present invention, a capacitive sensor is used to directly measure the displacement or vibration of stator wedges as a result of being struck by an impact hammer with a known force.
