A Lichtenberg figure (German: Lichtenberg-Figur), or Lichtenberg dust figure, is a branching electric discharge that sometimes appears on the surface or in the interior of insulating materials. Lichtenberg figures are often associated with the progressive deterioration of high-voltage components and equipment.
These tree-like lesions resemble feathering or ferning, and are also called Lichtenberg figures. [8] The marks are formed when capillaries beneath the skin rupture due to the electrical discharge and they usually appear "within hours" of the strike though they tend to disappear within a few days.
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 impurities, gas voids, mechanical defects, or conducting projections cause excessive electrical field stress within small regions of the di
Fractal burning, Lichtenberg burning or wood fracking refers to a technique where a Lichtenberg figure is burnt into wood using high voltage electricity. [1] [2] [3 ...
The lightning often leaves skin marks in characteristic Lichtenberg figures, sometimes called lightning flowers; they may persist for hours or days, and are a useful indicator for medical examiners when trying to determine the cause of death. Although humans being struck by lightning is of course rare, it is nonetheless possible that over a ...
