A Research of the Fractal Dimension Based on GIS PD Signals in Time Domain 1 1 1 2 QUAN Yu-sheng , *LI Wei , JIANG Shan ,XU Tie-ying (1.Key laboratory of high votalge EMC. BEIJING (NCEPU), Beijing, 102206, China; 2.Baoding Power Supply Filiale Company, Hebei, 071051, China) Emil: yhw-214@163.com Abstract—This paper introduced the definitions from the PD inspection test, it is intuitionistic and of box dimension and information dimension, and easy to understand, and contains all the analyzed the characteristics of these dimensions. In information of PD process which changes with this paper the fractal dimensions of GIS partial time, it’s the most accurate and detailed data. By discharge (PD) signals in time domain for the fault the calculation of fractal dimension about the PD of immobilized metal particles attached to time domain signal, fractal feature of PD time insulator surface were calculated, the variation-trend and relevant characteristics of domain signal can be described. The fractal related dimensions at different discharge stages feature has a special meaning for the analysis of were analyzed. This paper proposed that with the PD time domain signal. In this paper the box development of partial discharge, distribution of dimensions and information dimension of GIS fractal dimension have a significant partial discharge signals in the fault of transform
