Model trees have been analyzed with multifractal of general fractal and global spectrum trees in polymer. However these results do not have information of the place. It is difficult to consider the mechanism of the development of the tree. The new method of local fractal dimension map is proposed to analyze the electrical tree. At first model trees of both polarities have been analyzed with the conventional and the new method. Actual impulse trees for both polarities have been also analyzed. The branching in the progress can be estimated quantitatively.
