At a time of disassembling and assembling stator windings of a dynamo-electric machine in which the stator windings fitted in slots formed to an inner periphery of a stator core disposed inside a stator frame are disassembled therefrom and conveyed outside the stator core successively and new stator windings are then conveyed into the stator core and assembled into the slots successively, a mounting apparatus is arranged between the slot and an inside conveyer for mounting the stator winding into the slot. The stator winding is disassembled from the slot into which the stator winding is inserted while receiving and holding the stator winding by a receiving member provided for the mounting apparatus. The stator winding is then moved to the inside conveyer from the mounting apparatus and then conveyed from the inside conveyer to an outside conveyer. The described disassembling steps in the described order are repeated until a predetermined number of stator windings have been disassembled from corresponding slots and conveyed outside the stator core. Next, the stator winding assembling steps are carried out by steps substantially reverse to those described above till a time when a predetermined number of slots are assembled with the new stator windings.

Apparatus for assembling and disassembling stator winding of

An electric rotating machine comprises a rotor body of cylindrical structure and a stator body covering an outer peripheral portion of the rotor body in a non-contact fashion. The stator body includes a stator winding formed with an insulation layer and arranged radially outward of the rotor body with a clearance from the rotor body and a stator core which supports the stator winding. The electrostatic capacity of the stator winding is measured by an electrostatic capacity measuring instrument which comprises a housing having a size allowing the housing to be accommodated in the clearance between the rotor body and the stator winding, a support body detachably secured to the rotor body and adapted to support the housing within the clearance to be movable, and a measuring element mounted to the housing on the side of the housing facing the stator winding and adapted to measure electrostatic capacity of the stator winding, wherein a degree of water penetration into the insulation of the stator winding is determined based on a measurement data from the measuring element.
