摘要：

Experimental evidence is provided to show that irreversible aging which leads to electrical treeing in polymeric insulation, such as low-density and crosslinked polyethylene used in HV transmission cables, does not start at local fields between 5 and 20 kV/mm. It is shown that a much higher stress is required for electrical tree inception and that the electroluminescence inception voltage is the threshold voltage at which the polymer starts to degrade.
