MECHANICAL INTEGRITY CHECKING OF GENERATOR STATOR

The stator winding conductors are insulated by ‘F’ class epoxy based mica insulation. Overhang conductors of stator winding are supported on stator casing by fiber glass ring and fiber glass blocks. Conductors at overhang are tied with the fiber glass ring by polyester cord. Near the exit point of the conductor from core, one epoxy putty ring was made to reduce overhang conductor vibration. Top and side ripple spring has been provided in the slot to further reduce conductor vibration.
