Abstract In this paper, an actual 15kV XLPE cable was used to test electrical tree, and its electrical stress enhancing was simulated by a metal needle defect. The growth of electrical trees was detected by the digital partial discharge (PD) measurement, and the structures were observed by optical microscopy. The chaos analysis for the time series of maximal and total PD data indicates that the propagation of the electrical trees show the characteristics of the deterministic chaos. And its maximal Lyapunov exponent and correlation dimension of the strange attractors increase with the decrease of the fractal dimension of the trees.

Key words： XLPE cable electrical tree partial discharge chaos fractal dimension
