Abstract :
In this paper, the impulse trees in the polymeric insulator polymethylmethacrylate (PMMA) have been measured three-dimensionally utilizing a CT (computed tomography) method. Successive impulses were applied at the needle electrode. The figure of the tree was restructured in each step, and the generalized dimensions and the global spectrum were calculated for positive and negative impulses
