Abstract :
This paper proposes a new diagnosis method for aging deterioration of insulating paper. We would like to note that the thermal deterioration of insulating paper accompanies crystallization of cellulose fibers. In this paper, we investigated the relationship between deterioration and crystallization of cellulose fiber by using the dispersion staining method.
