1. A barjacking test unit for measuring radial movement of generator stator bars in-situ, the barjacking test unit comprising:

  • a linear voltage displacement transducer (LVDT) secured to a frame, the LVDT including a spring biased displacement measuring arm;

    a bar sensor engageable at an exterior end with a stator bar; and

    a pivot bracket pivotally secured to the frame and disposed between an interior end of the bar sensor and the spring biased displacement measuring arm of the LVDT, wherein the spring biased displacement measuring arm urges the bar sensor toward engagement with the stator bar via the pivot bracket.
