Chaos Analysis of Discharge Current on Phenolic Resin under Reduced Pressure

The experiment of this research was carried out on a phenolic resin laminate in accordance with IEC60112 under a reduced pressure. In order to assess the performance in the tracking test, the chaos theory was adopted. According to the characteristics of statistical self-similarity and complexity of discharge current in the tracking test, the fractal dimension was calculated based on the G-P algorithm, and the strange attractor was reconstructed by using Takens theory. The C-C method was used to estimate the delay time. Obtained results show that the correlation dimension and the Lyapunov exponents show a similar tendency with the decrease of the ambient pressure
