In electrical engineering, treeing is an electrical pre-breakdown phenomenon in solid insulation. It is a damaging process due to partial discharges and progresses through the stressed dielectric insulation, in a path resembling the branches of a tree. Treeing of solid high-voltage cable insulation is a common breakdown … See more Electrical treeing first occurs and propagates when a dry dielectric material is subjected to high and divergent electrical field stress over a long period of time. Electrical treeing is observed to originate at points where … See more Electrical trees can be further categorized depending on the different tree patterns. These include dendrites, branch type, bush type, spikes, strings, bow-ties and vented trees. The two most commonly found tree types are bow-tie trees and vented trees. Bow-tie trees Bow … See more • Detection and location of electrical trees by partial discharge measurement • Partial Discharge and Electrical Trees See more Electrical trees can be detected and located by means of partial discharge measurement. As the … See more • Cross-linked polyethylene • High-voltage cable • Lichtenberg figure • Partial discharge See more WebThe water treeing phenomenon is considered from the viewpoint of how far dielectrophoresis can be the decisive phenomenon. In the model concept discussed, a locally increased electric field leads to a local increase of the concentration of water molecules. The consequent precipitation of liquid water produces water trees.
