Abstract :
New AC current shunts are developed, which are designed for measuring AC current up to 50 A, 50 kHz. Due to the effect of parasitic parameter, the calibration accuracy of large AC current at high frequency is not as high as the AC current of normal range. About the large AC current at high frequency, the accuracy mostly depends on inductive impedance influence.
