Abstract
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.
