Abstract The impulse current is a transient current waveform, which has a short duration and can not be repeated, so it is difficult to evaluate the influencing factors of measurement errors. A fast response precise impulse shunt is developed. The measuring principle and size design of the shunt are analyzed. The transient response process of the shunt is studied. The output signal is welded to the outside of the resistor to eliminate the skin effect. The steady resistance of the shunt is 0.9697mΩ_and the stray inductance is 32nH. When the rated current is measured, the temperature rise of the resistance is less than 36℃. A step current generator is developed to measure the dynamic characteristics of the shunt. The step response time of shunt is less than 4ns. The convolution integral method is used to calculate the peak value and time parameter measurement error caused by the dynamic characteristics. The linearity, stability of the shunt are tested under 8/20μs. The uncertainty is evaluated by shunt and digital recorder separately. After analyzing the uncertainty components, the measurement uncertainty of the whole system is calculated to be 0.41% (k=2). It shows that the measuring device can be used as a standard measuring device for the calibration of current sensors.
