Abstract：In this paper, the magnitude and the waveform of the positive and negative voltage to ground voltage in different parts of the generator excitation circuit are studied, and the method of determining the location of the grounding voltage by the rotor to ground voltage is presented. At the same time, the research method is used to analyze the rotor grounding fault of generator, and the positive and negative of the rotor of the generator is in complete agreement with the analysis in the paper. The analysis method presented in this paper has important reference value for finding fault location and fault location in the field of generator excitation circuit.
