Abstract: The measurement accuracy is the most important function for the calibration system of electronic current transformer.According to the correlative industrial standards and aiming at the accuracy grade of 0.05,this article designs the calibration system technical scheme and analyzes he error component of each section.With the measurement uncertainty theory of the metrology,the uncertainty sources are analyzed and the evaluation method for uncertainty of calibration system is given.

Key words: calibration system of electronic current transformer, error analysis, measurement uncertainty
