www.ge.comA “tight” stator winding can last two or three times as long as a winding that is not firmly held in the stator core . The test performed by the MAGIC system is similar to the test used in the factory for new units . One component of this assessment is the wedge tightness or wedge tapping test that examines the tightness of the stator slot
