The four sets of stator bars including those retired from three large generators and the standby bar subjected to Dynamic Mechanical Analysis, Scanning Electron Microscopic and optical microscope observation. It was revealed from DMA that the peak value tan d m of mechanical loss thermogram tan d ~ T shift toward a higher temperature and a lower amplitude, indicating that the amount of movement monomers diminished greatly in the insulation aging process, the tan d 195, increased very slightly with the service time of insulation, showing the degrading of bonding properties at interface, and the presence of more defects in insulation. The observation of SEM and optical microscope showed that more and more voids appears in insulation, and delamination was formed due to development of voids in aging process.

对不同运行年数的线棒进行了 DMA 、 SEM 、光学显微镜等微观分析试验，动态力学分析发现(参见 Hao et al， CEIDP， 2002：404)，力学损耗温度谱 tan d ~ T 的峰值 tan d m 随老化时间向高温、低值方向移动，表明促成环氧发生玻璃化转变的活性侧基或发生局部运动的活性链段减少，分子链的刚性增强；195℃的力学损耗 tan d 195随老化时间有缓慢增大的趋势，表明有更多的能量耗散在界面处，界面的粘合性变差，甚至由于界面粘结不良出现微观缺陷； SEM 和光学显微分析发现(参见 Hao et al-2， IEEE DEI， 2003)，老化后的绝缘气隙增多，随着老化时间气隙不断扩展或相互连通，绝缘逐渐分层。
