Abstract
An AC shunt calibration system using a current-bridge method is developed, and its measurement uncertainties are estimated. A comparison of the calibration results obtained using the current-bridge method with the results using DC resistance and AC–DC difference methods was performed to verify the system. These comparison results show that the current-bridge-based system performs well with small measurement uncertainties for both the AC resistance and phase angle of the AC shunts up to 1 kHz.
