Abstract Various neutral point overvoltage which may occur in the isolated neutral system transformer were presented in this paper, and the installation of neutral point arrester can keep the device from destroying. Whether the arrester is selected correctly or not is directly related to the normal system operation. The selection principle of the transformer neutral point arrester and the precautions of the maintenance process were proposed through the analysis of the breakdown of the transformer neutral point arrester caused by the line grounding fault and the finding of the fault location.
