Abstract：This study used correlation analysis and independent sample t-test to analyze the electrical safety data of three models of the high-frequency electrotome to verify the relationship among various detection parameters and the differences among the parameters of different brands. The results indicated that earth leakage current occurred when the earth wire broke down can run into the earth through other ways. In addition, earth leakage current, enclosure leakage current, patient leakage current and patient auxiliary leakage current affected with each other mutually.
