The purpose of this study is to determine the ageing mechanism of Mica/Epoxy composite material for large generator stator windings in order to estimate remaining life of generator.
X-ray analysis is performed to investigate the position and structure of mica crystal in insulation materials. The phase change of aged and sound specimen under each atmosphere isn't observed.
Surface analysis of insulation materials by optical microscope also show that the sound and aged specimen, sliding phenomenon by shear and thermal stress is observed both interface between mica and epoxy.
