摘要：

This paper describes a calibration system for AC shunts using digital sampling. It provides both ratio errors and phase displacements of a shunt under test with respect to a reference shunt. In its basic configuration, the calibration system operates at currents of up to 10 A and frequencies of up to 10 kHz. The expanded uncertainties (k = 2) of the described calibration system are estimated to be better than 30 mu A/A for magnitude and 30 mu rad for phase at 10 kHz, and lower than these at lower frequencies.
