Abstract :
The degraded region is formed even at low voltage almost equal to electroluminescence (EL) starting voltage, and then tree channel grows from the degraded region. This paper reports the relation between the progress of polymer degradation and EL intensity, and discusses the process at the very early stage of tree initiation including the formation of tree channel without gas discharge.
