Partial discharge pattern recognition is an important way to assess insulation condition of electrical equipment.Fractal theory is effective to extract features of PD.Based on the construction of gray image of XLPE PD signals
this paper determines the scaleless range by piecewise search
selects the box-dimension and information dimension as the input variables for artificial neural network and carries out PD pattern recognition.Results indicate the extracted fractal characteristics can meet the requirements of PD pattern recognition.
