Partial Discharge (PD) on-line monitoring can detect the insulated defect of electric equipment effectively, which will prevent suddenly accident. On the basis of PD mechanism research, the relation between PD detecting signal non-linear dynamics eigenvcctor and insulation defect pattern is investigated by experiment. Using the characteristic parameters, such as Lyapunov exponent, Kolmogorov, fractal dimension extracted from the PD detecting signal time sequence data to be the eigen vector of PD pattern identification. A series of typical insulation PD experiments is carried out in the lab. Th...
