摘要：
According to the problem of high cost of standard apparatuses and complex operating for the traditional AC current measurement, this paper introduces a method to measure the AC current with high performance which is based on using digitizing system and the AC-DC difference calculable resistance. Compared verification tests indicate a maximum deviation of 2.3x10(-5) between the digital sampling measurement system and the traditional method in the typical frequency range of 40Hz to 10kHz, which achieves the equivalent technical specification. Meanwhile, it can provide a more reliable and simpler way for AC current calibration.
