초록
In pumped storage Generator-motor stator windings gradually deteriorates due to mechanist, thermal, electrical stresses. These stresses combine to result in loose windings, delamination of the stator insulation and/or electrical tracking of the endwinding, all of which can lead to stator insulation failures. Since the degration of generator-motor is gradually occurred, regular inspection system is necessary to monitor degrading. The result of this diagnosis is a basic for the maintxnance of generator-motor.
