抄録

This paper describes the change in the partial discharge (PD) characteristics due to the growth of electrical trees in insulating materials under the application of an AC voltage. An electrical tree consists of branch-like dielectric breakdown paths. Investigation of a number of characteristic PD parameters shows that the φ- q distribution profile has a good correlation with tree growth. The φ- q distribution expresses the average pulse height as a function of the AC voltage-phase angle. The distribution indicates a common profile for trees growing in both epoxy resin and polyethylene. Tree growth in these materials can thus be detected by monitoring the profile of the φ- q distribution, and the final breakdown can be predicted from the tree growth.
