The effect of absorbed oxygen on electrical treeing in polymers
This paper describes the effect of the oxygen absorbed in the free volume of polyethylene on electrical treeing phenomena. The ac tree initiation and growth were investigated at room temperature using virgin samples and also samples degassed by a vacuum pump. The tree starting voltage of the degassed samples is much higher than that of virgin samples. The experimental results show this improvement can be attributed to the removal of oxygen from PE. We also observed in detail the processes of tree initiation and growth in the degassed samples. The observations with other results led us to conclude that the charge carriers injected from the point electrode play a dominant role in the tree initiation.
