Based upon the gray system theory, the new mode of gray forecasting model for electrical insulation fault diagnosis and its application were studied. Firstly the new mode of gray forecasting with first-order fitting parameter suited for electrical insulation fault diagnosis was established. And then the modeling process for the new mode was presented. Finally the method was presented which was processing original data by means of the effect of weakening operator and the first-order exponent flatness operation, and then re-constructing background value, and according to the field example examination, the result shows that such method is feasibility and validity.
