Abstract According to the working principle of residual current transformer, phase displacement and ratio error are the main factors causing error. The influence of error on the transmission characteristics of sensitivity and balance is obtained through formula analysis. Considering the influence of device parameter values in product design, the physical characteristics of residual current transformer is further optimized through experiments to verify the conclusion of principle analysis and determine the transmission characteristics of sensitivity and balance of residual current transformer under different conditions. The experimental results show that the optimization is reasonable, and a residual current transformer with high precision up to 0.5 level is designed.
