摘要：

The inception voltage of electrical treeing and the length of the electrical treeing path in low density polyethylene (LDPE) were examined using a needle-plane electrode system, by applying an AC voltage with a frequency of 10-120 Hz. In order to obtain the relationship between the length of the electrical treeing path and the space charge distribution in LDPE, thermally stimulated current measurement was employed using a similar needle-needle electrode system. It was revealed that the length of the path generated due to the electrical treeing was approximately the same as the depth of electrons injected from the needle electrode.
