This paper describesthe mechanism of tree initiation in low density polyethylene for AC voltages.
Experimental results of remperature dependence of rate of tree initiation, relation between applied voltage and time to tree initiation at 50%, and relation betwin Δx and applied time of voltage indicate that
1. equation t=AV^-n is formed from relatio between applied voltage and time to tree initiation at 50%, and the value of n is larger velow -10˚C than 20 ~ 80˚C.
2. tree length is grown to rising appled voltage, but not grown to applied time for the same applied voltage.
3. temperature rising reduce the initial electrical tree voltage.
